Wearable enclosures

OKW wearable enclosures are ideal for electronic components and sensors that are worn on or close to the body – the new generation of ‘wearable technologies’. Our ergonomic and aesthetic enclosures enable wearable computers and other on-the-body electronic devices to function simply and elegantly, without restricting the user. Their simple operation by means of keys, touch screens or push buttons offers users complete control in all situations – reinforcing their feelings of security and well-being and reducing stress. Larger versions have a convex design to match the curves of the body and offer a generous surface area for interfaces. Our smaller enclosures are highly practical and unobtrusive. Accessories include comfortable wrist straps or hand straps, belt/pocket clips and fastening eyelets for attaching lanyards and belt straps etc.

Enclosures for suspension arm systems

OKW operating and display enclosures are ideal for mounting on tripods and suspension arm systems. Several models have integrated handles, which are particularly suitable if the display and control panels have to be realigned frequently. Effortless swivelling, tilting, inclining, turning, pulling etc. – all this is no problem. Alternatively, there are also flat housings for operating panels. The narrow design of these, as well as the finger recesses on the back, ensure that the unit is securely held during positioning.
These enclosures also offer generously dimensioned operating panels for displays and touch screens from 16 cm (6.4 inches) to 34 cm (13.4 inches). The rear interface mounting allows tidy cable routing via the enclosure connection, the system is partly compatible with the VESA standard (100 x 100 mm).

CARRYTEC M - Enclosure with flat bottom part

The CARRYTEC M, the enclosure with the handle, is now also available as a flat version as an alternative to the existing version with the high bottom part. The new version has a reduced installation depth and is ideally suited to devices in which a flat volume has to be packaged. However, it still offers enough room for interfaces while retaining its slim appearance.

The CARRYTEC M is available in two different materials - ABS (UL 94 HB) in off-white (RAL 9002) and in a reinforced, impact-resistant plastic material, ASA+PC (UL 94 V-0), in lava. The dimensions of the flat version are 270 x 247 x 42 mm (W x H x D) and are thus ideal for holding a tablet computer, for example. Thanks to the optionally available sealing, the enclosure offers protection class IP 54, and is thus ideal for many different requirements and tasks, both indoors and outdoors. The CARRYTEC offers a perfect non-slip grip thanks to a soft TPE insert in the handle. The special feature of this group of products is a large surface which can be used for user interfaces. The recessed operating area offers optimum protection for membrane keyboards. Besides the mobile version, the CARRYTEC can also be used on a bracket or tripod by means of a 180° rotation. The existing holding clamp for hanging the enclosure on round tubes and equipment rails (DIN EN ISO 19054) can be used on the high as well as on the flat bottom part.

Numerous processing and finishing options, for example mechanical processing, lacquering or printing, allow the enclosure to be individualised according to customer's wishes. The applications of the CARRYTEC include medical and laboratory technology, data acquisition and safety technology, measurement and control technology, and much more.

CONNECT - The optimum connection

With the new CONNECT, OKW Gehäusesysteme presents a versatile and compact plastic enclosure for wired applications. It consists of two enclosure shells which are easily and reliably joined together by means of a concealed locking edge. The two end sides are designed in such a way that either they are closed or they can be fitted with cable glands. The possible applications include security and building services systems, computer peripherals and network technology, data transfer, measuring and control engineering as well as medical technology.

On account of their functions, the CONNECT enclosure shells have different shapes: the one is convex, the other somewhat flattened with a recessed panel for accommodating operating units. They have identical recesses at both ends for end elements. To connect the two shells, they are simply snapped into each other, which means time savings during assembly. The absence of screws enhances its appearance, on the one hand, and on the other hand the front face of the enclosure can be freely selected. Cable glands and/or end parts are optionally available to complete the enclosure shells. It is for example possible to suspend the enclosure by using an end part on the one side and a cable gland on the other. Two cable bushings are also possible if the enclosure is to be used as an interface between several devices. The cable gland kit contains an integrated strain relief device, that is, the cables are clamped within the gland. A holding clamp which has a concealed attachment to the enclosure is available for hanging the enclosure on pipes and on common round profiles. The flattened enclosure shell has four attachment domes for mounting PCBs and built-in components.

Robust, UV stabilised plastic material ASA+PC-FR (UL 94 V-0) in the colour off-white (RAL 9002) is used to manufacture the enclosure. They offer protection class IP 40 and are available in 3 sizes (L x W x H): 76 x 54 x 22 mm, 116 x 54 x 22 mm and 156 x 54 x 22 mm.

For optimum modification of the CONNECT for different applications, processing and finishing techniques are available such as mechanical processing (e.g. for additional cutouts on the long sides), printing, lacquering or EMC coating by the in-house service centre.

BODY-CASE – Small enclosure with flair

The new BODY-CASE is the first wearable enclosure by OKW Gehäusesysteme and is ideal for applications on or near the body. Thanks to its small, compact format, it is perfect for wearing on the body: on your arm, around your neck, in shirt and trouser pockets or carried loose in an article of clothing. The enclosure fulfils its function in the simplest way, without restricting the user in his or her activities and without being conspicuous.

The body case has a three-part design consisting of a top and a bottom part and a matt TPE sealing ring. The enclosures are made of ASA material in the colour traffic white (RAL 9016) and have a modern appearance thanks to highly polished surfaces. The top parts are available from stock, either with or without a recessed surface for decor foils or membrane keyboards. The sealing ring is available in the colours vermilion (RAL 2002) as well as lava (similar to anthracite) and allows protection classes IP65 and IP67. The dimensions of the enclosure are 54 x 45 x 17.5 mm (L x W x D). Internal power can be supplied with round or button cells which are mounted directly on the PCB. Alternatively, It is possible to charge the device inductively after the installation of a rechargeable battery with copper loop.

The BODY-CASE can be worn comfortably on the arm with the help of optional accessories, for example a black silicone wrist strap or a hand strap. A fastening kit, consisting of belt / pocket clip, fastening eyelet, e.g. for a lanyard, and two covers for closing the rear wrist strap attachment, is also available. The enclosure can also be worn loose in an article of clothing. Possible applications include mobile data recording and data transmission, measuring and control engineering, digital communications technology, emergency call and notification systems as well as bio-feedback sensors in the fields of health care, medical technology, leisure and sports etc.

The enclosure can also be modified further for different applications. Processing and finishing techniques by the in-house service centre are also available, such as mechanical processing, printing, EMC coating and much more.
