Mobile devices require functional and visually appealing packaging. Handy, flat dimensions, yet at the same time with a lot of volume, are ideal for universal installations and modern radio standards. The new SLIM-CASE series of handheld enclosures by OKW Gehäusesysteme, with their slim design and their choice of different operating fronts, is ideally suited for these mobile electronic applications.

Thanks to its design, the flat SLIM-CASE is ideal for modern handheld control units. It lies comfortably in the hand and looks particularly attractive. The enclosure range includes one top and one bottom part each, made of flame-resistant ASA+PC-FR (UL 94 V-0) in off-white (RAL 9002). Assembly is effected from behind, using four TORX stainless steel screws. This gives an attractive appearance, since no screw heads are visible. The SLIM-CASE is available in six versions in the dimensions (length x width x height) 148 x 74 x 19/22 mm. You can choose between three different operating panels:

  • Recessed 1.6 mm: for the use of a contoured transparent front screen or for membrane keyboards.
  • Recessed 1 mm: for applications with decor foils.
  •  Flat operating panel: for individual design and arrangement of operating and display elements of all kinds.
These three versions are each available with two different bottom parts: with or without raised pillar for the optional TPE intermediate ring in volcano. This increases the installation volume by 3 mm and also serves as shock protection. As a further accessory, there is a transparent front screen (rear side printable on request) to protect the displays underneath. The whole thing is fixed with an adhesive foil. With the intermediate ring the enclosures achieve protection class IP54 or IP65 with an optional seal, allowing the SLIM-CASE to be used both indoors and outdoors.

The slim design makes the enclosures ideal for the installation of flat electronic components as well as large-area displays and touch applications. The possible fields of application range from measuring and control technology, IoT/ Medical IoT, through health care, laboratory and medical technology and environmental technology to wireless communication. The SLIM-CASE can be modified as required, for example with mechanical processing for interfaces, the printing of company logos, painting in different gloss levels or in metallic paint, EMC aluminium coating, membrane keyboards and much more.

Sudden fall. Getting up under your own power is no longer possible and you may even have suffered a serious injury. This is where emergency call systems can be of decisive help! They support senior citizens and people in need of help in their daily lives, warn them of dangers and, in an emergency, notify their relatives or the rescue service. Enclosures from OKW make a decisive contribution to this - whether as a portable version on the body, fixed to the wall or as a base station on the table.

The fear scenario for many single seniors is simply: What happens if I fall down and nobody notices? It can happen at any time! With increasing age, the ability to see and hear declines. Muscle strength, coordination and reaction speed decline, and chronic illnesses often make life more difficult for many older people. Emergency call and assistance systems, however, give seniors the necessary security to master everyday life and relatives a good feeling, even if they are not in the immediate vicinity. With both home emergency calls and mobile emergency calls, seniors carry a mobile transmitter with them. If something happens to them, they press the button on this transmitter. This causes the device to trigger an alarm at an emergency call centre, which immediately attempts to contact the person concerned. If this is not possible or if there is an emergency, the emergency call service staff will inform relatives, the family doctor or the ambulance service as required.

OKW's wearable cases are perfectly suited for these mobile emergency call applications. The BODY-CASE, for example, can be worn on the wrist like a watch. With the wide range of accessories, however, there are many more possibilities: wearing around the neck with a neck strap, wearing on the body or pockets with a clip-on or simply loosely inserted. The case series can be delivered in 2 different sizes, with and without recessed control panel. The intermediate ring made of soft TPE material enables optical differentiation (e.g. for special injection moulding from 200 pieces in individual company colour) and the high protection class IP65. Thus the electronic components are protected against water jets when washing hands or cleaning.

In the classic version, emergency call systems for senior citizens transmit the emergency call via radio from the hand-held transmitter to the base station. The base station immediately alerts the stored telephone number. Base stations can be used as tabletop versions or space-saving wall-mounted versions. The OKW housing portfolio includes a wide range of options for this - depending on the required volume of the built-in electronics, the number of keypads/operating elements and the customer's personal design preferences. That is why we are "picking out" a series of enclosures called SYNERGY at this point. The desktop and wall-mounted enclosures are characterised by their high-quality appearance, consisting of an aluminium profile with a top and bottom part each made of black plastic. There are 36 enclosure sizes available in 4 basic shapes: round, oval, rectangular and square. The SYNERGY, like pretty much all OKW enclosures, can be modified according to individual customer requirements, with e.g. printing, mechanical processing for interfaces/displays, a paint finish and much more.

Intelligent assistance systems (AAL Ambient Assisted Living) go one step further, in addition to the pure emergency call function. The basis is a self-learning system in which sensors are networked with each other to collect and evaluate data. In this way, routine tasks and habits of the senior citizens are recorded. AAL systems can, for example, automatically take over the control of lighting and room temperature. Another possibility could be fall sensors in the floor, which detect if a person is lying on the floor for a long time. Sensors in ceilings/walls or in the shower check the resident's movement profile and also trigger an emergency message in the event of deviations or need. You can find an application example under the attached link. The AAL assistance system collects information as well as sensor readings and thus enables early hazard detection and reminder function. For example, if someone leaves their home while the cooker is still on, the system can issue a warning or switch the appliance off automatically.

Medical technology is a highly regulated but also continuously growing industry. The focus is on people – products, equipment and processes are constantly being developed and manufactured for the prevention, diagnostics and therapy of diseases. High-quality empty enclosures and tuning knobs by OKW make a significant contribution here.

Medical technology is an vital market for us ! In day-to-day use by doctors, nurses or patients themselves, products are required for a variety of applications: whether as emergency systems, observation and alarm equipment, analysis/diagnostics/therapy devices, tracking and monitoring, the medical IoT, AAL systems and ergonomic remote controls (wireless or wired). OKW has suitable solutions in its product portfolio for all these medical "cases". Here are some examples:

The integrated handle and the particularly large surface that is ideal for user interfaces are the key features of the CARRYTEC enclosure range. But there is much more technical know-how behind it, and this allows a wide range of possible applications in medical and laboratory technology. Mobile use, e.g. as a patient simulation system, can be effected easily and ergonomically thanks to the functional carrying handle. The CARRYTEC is available from stock in 3 sizes, each in the colours lava or off-white (RAL 9002): size S has the dimensions 222 x 205 x 80 mm, M has 270 x 247 x 91 / 42 mm and the L version 348 x 303 x 117 mm (W x H x D). Separate protection bags for storing instruments, sensors and accessories can be attached to the sides of the enclosures in the S and M versions. Thanks to its generous installation depth, CARRYTEC offers plenty of space for interfaces, yet has a slim appearance. The CARRYTEC can be attached to rectangular DIN standard rails or round tubes with a separately available holding clamp. Rear installation on tripod or support arm systems - then rotated by 180° - allows fast positioning/alignment of the viewing and operating panels.

In medical technology, not only large-volume devices are required, ergonomic handheld enclosures and portable technologies (Wearable Technologies) are also becoming increasingly popular. They collect and supply important data, e.g. on patients’ health status, they report and monitor the location of persons in care facilities who are in need of help, allow an alarm or emergency call to be made, and so on. The BODY-CASE was developed precisely for such purposes. The enclosure shells are highly polished and are made of ASA (UL 94 HB) in traffic white (RAL 9016). The matt TPV 50A sealing ring is available in the colours vermilion (RAL 2002) as well as lava (similar to anthracite) and guarantees the high protection class IP65. The dimensions of the BODY-CASE L are 55 x 46 x 17 mm (L x W x D), while the M version has the dimensions 48 x 40 x 14.5 mm. With the help of the wide range of accessories such as wrist straps, belt / pocket clips, carrying straps or lanyards, the units can be carried comfortably on the wrist, on clothing or around the neck. After use, a station ensures safe storage of the wearable device.

OKW Gehäusesysteme has a wide range of modern tuning knobs for operating medical devices, such as intensive care ventilators etc.
The TOP-KNOB range of tuning knobs is particularly suitable for rotary potentiometers with round shaft ends in accordance with DIN 41 591 as well as flat shaft ends with diameters of 6/4.6 mm. Mounting is effected from the side by means of a threaded pin, or simply by pushing them onto shafts with flattened ends. The lateral screw fixture is innovatively concealed by functional marking elements in different colours and shapes. TOP-KNOBS are available in 5 diameters (16/20/24/31 mm and 40 mm) as well as in the two standard colours nero and volcano.

The main characteristic of COM-KNOBS is their modern appearance. Assembly is effected by means of a tried and tested collet fixture for electromechanical rotary potentiometers with round shaft ends in accordance with DIN 41 591. The design of this series of tuning knobs is based on that of the TOP-KNOBS with an identical choice of colours and materials as well as the same 5 sizes (with an additional sixth version with a diameter of 50 mm). This allows a homogeneous appearance if both knob types are used.

As standard, the series of tuning knobs consists of three components: the basic body, the cover and the marking element. Closed versions without corresponding marking elements are also available for universal use or if additional parts such as dials are required. To ensure rational handling while operating or adjusting the end devices, covers with finger recesses are available for the two largest variants, 40 and 50 mm.

With the new CONTROL-KNOBS, OKW Gehäusesysteme offers an advanced series of rotary knobs as a central element of menu-controlled interfaces. The grip surface made of soft-touch material enables easy gripping, a pleasant feel and ergonomic operation. The high-quality appearance can also be illuminated if required.

The modern CONTROL-KNOBS are designed for user-friendly use and consist of hard and soft plastic components: Button base body made of high-quality PC (UL 94 HB), encased in a soft TPE material with a functional grooved look. Due to the soft-touch material, the new knobs have a high grip with anti-slip effect. The CONTROL-KNOBS are mounted using collets which guarantee a secure fit on the shaft - ideally suited for rotary potentiometers/pulse generators with round shaft ends according to DIN 41 591. For final assembly, a cover made of PA 6 (UL94) is attached to the base body. The CONTROL-KNOBS are available in the standard colours nero and vulcan in the following sizes:
  • ø 36 mm, with axle hole 6 mm and 1/4" (6.35 mm)
  • ø 46 mm, with axle hole 6 mm and 1/4" (6.35 mm)
Both sizes are available with/without lateral pointer line for fine scaling. As an optical highlight for the ø 36 mm version, an optional illumination sets an impressive accent. The smaller CONTROL-KNOBS can be equipped with energy-saving SMD LED technology for individual lighting results. In this variant, the basic knob body is not traffic white, but made of translucent material. This results in the following lighting options:
  • Ring optics on the cover surface
  • Ring optics on the top surface with lateral pointer line
For the illumination of the ring, the base available in the accessories range, together with the LED illumination (RGB backlight), is necessary. Application areas include measurement and control technology, medical and laboratory technology, smart factory, communication and much more. In order to adapt the buttons to special customer requirements, they can be modified by means of printing or laser inscription on the cover surface/lid.
