PROTEC - Square control centre

OKW’s new PROTEC enclosures have a modern and highly attractive square design with soft contours. As a result, these wall-mount and table-top housings are ideal for modern electronics applications, both indoors and outdoors.  The enclosures have an inclination angle of 20° which considered ergonomically ideal for operating terminals and for reading off data.

PROTEC can be ordered from stock in 3 sizes with 140 x 140 x 76 mm, 180 x 180 x 92 mm, 220 x 220 x 108 mm (W x D x H) and is also available in 3 different versions:

  • Version I - With a deep recessed interface area at the rear of the enclosure for the installation and protection of connectors, interfaces, switches and cables.
  • Version II - As version I, but also with a snap-on cover for flush covering of the recessed interface area.
  • Version III - As version I, but with a deep cover for the recessed interface area which is fitted by screws. The deep cover provides additional internal space for the electronics, cabling and connections.
A recessed operating area for integrating membrane keyboards, operating elements and touch systems has been provided in the square top cover. The top cover is screwed to the bottom part at the back with stainless steel Torx screws, and the entire screwed connection is thus hidden from view. The range of accessories for the enclosure series includes matching sheet aluminium holders, which allows hidden, secure wall mounting. As can be expected from OKW, the PROTEC enclosures can also be modified according to the individual requirements of the customer, for example with printing, mechanical machining for interfaces/displays, painting, EMC coating on the inner side of the enclosure and much more.

The PROTEC-series is made of high-quality V0 material in off-white (RAL 9002). The electronics compartment can be sealed up to protection class IP 65 by means of an accessory sealing kit – this is particularly useful for tough applications, for example in the smart factory / IIoT, central control units, surveillance systems and access and security controls in industrial environments or outdoors. However, the PROTEC can also be used in many other sectors: for data acquisition systems, data systems engineering, measuring and control engineering as well as medical technology and in health care.

EVOTEC enclosure family extended by another standard size as well as a wall suspension element

With the new enclosure size 100, the range of Evotec enclosures by OKW Gehäusesysteme has grown further. The small EVOTEC 100 is ideal for applications that require a reduced installation volume. The enclosures are particularly robust and are suitable for harsh working environments. The enormous variety of applications is rounded off by a wall suspension element for the sizes 200/250. Examples of possible applications would be measurement and control engineering, control technology, GSM modules, networks, medical and laboratory technology or information technology.

The new EVOTEC 100 enclosures are available with 2 flat top parts that differ only in height. The EVOTEC 150/200 or 250 from the standard range are suitable for even more installation volume, and desktop versions with/without recessed surfaces are available in the sizes 200 and 250. The dimensions of the EVOTEC 100 enclosure are 100 x 62 x 26/31 mm (L x W x H). The other versions are available with the following dimensions: 150 with 150 x 93 x 35/45 mm, the 200 version with 200 x 124 x 45 mm and the EVOTEC 250 with 250 x 155 x 54 mm. Pleasant contours guarantee an elegant appearance. All versions are made from high-quality ASA+PC-FR with high UV protection. Thanks to the optional seal, the enclosures achieve protection class IP65. Rubber feet included in the supply ensure reliable desktop positioning.

With the new suspension element, suitable for the versions 200/250, the enclosures can now be mounted quickly and easily on the wall. One part of the suspension element is mounted on the rear side of the EVOTEC. Its "counterpart" is screwed to the wall. You can now easily click the enclosure onto the wall element or also remove it again. A screw connection of the two wall suspension components from below provides for more safety and protects the enclosure from unauthorised removal. Applications with the suspension element are conceivable in the field of wearables or also wireless communication. Additional modifications, such as mechanical processing for interfaces, lettering, painting/special colours and printing or EMC coating allow the enclosure to be customised according to the user's individual ideas.

BODY-CASE – New enclosure size and station to match

The wearable enclosure BODY-CASE range by OKW Gehäusesysteme has been extended by a smaller size. In addition, a cradle is also available now to let you put down the enclosure safely or, if necessary, to be able to charge it. Possible applications of the BODY-CASE 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 range is ideal for portable technologies, so-called "wearable technologies": it can be carried around your neck, on your arm or wrist, on articles of clothing or loose in a sewn pocket. The "wearable enclosure" is particularly unobtrusive and does not restrict you in any way, and is like an accessory. The enclosure shells of the BODY-CASE are highly polished and are made of high-quality ASA (UL 94 HB) in the colour traffic white (RAL 9016). The top parts are available from stock, either with or without a recessed surface for decor foils or membrane keyboards. The matt TPV sealing ring is available as standard in the colours vermilion (RAL 2002) as well as lava (similar to anthracite) and allows protection class IP65. The BODY-CASE range is available in two different sizes with the dimensions (L x W x H) 55 x 46 x 17 mm (L), and the recently released version M with 50 x 41 x 16 mm. Depending on the operating elements and electronics you require, you can choose the right size for your application. On the arm, the smaller version is also conceivable as an attractive alternative for people with a more slender wrist. In this way, the terminal makes neither a bulky nor a distracting impression. There are also various matching accessories such as a wrist strap, a belt / pocket clip or a lanyard. In addition, a station is now also available for both enclosures. This means that the BODY-CASE can be kept safely after use, and an integrated charging option is also conceivable.

For different applications, the enclosure can also be modified according to customer requirements. Processing and finishing techniques by the in-house Service Center are also available, such as mechanical processing for interfaces and printing.

SMART-TERMINAL – Aluminium profile enclosure for robust display applications

With the new SMART-TERMINAL enclosure range, OKW Gehäusesysteme offers an elegant, flexible and robust aluminium profile enclosure in its standard product programme. A uniform profile cross-section with variable length design as well as matching accessories allow a flexible variety of applications as a table-top or wall-mounted version.

The new SMART-TERMINAL range of enclosures consists of a C-shaped top profile made of anodised, glass bead-blasted aluminium. It includes a recessed area for membrane keypads/decor foils and flat interface surfaces on the sides. There is sufficient space here for operating elements, switches or displays. The flat base profile is also made of aluminium and closes the enclosure from below with 6 screws. On the open profile sides, the SMART-TERMINALs are closed with covers made of high-quality ASA+PC-FR material in the colour lava. For the plastic parts there are separate moulded seals in the colours volcano or green (RAL 6016). Interfaces such as plugs and connections are also possible through the covers. The complete enclosures are available with profiles in the dimensions 170 x 50 mm (width x height) and in the profile lengths of 160 mm, 200 mm and 240 mm. With the covers, the overall length of each size increases by 42 mm. The versions were designed to fit standard display and touch solutions from 4.3" up to a maximum of 8". The length 200 mm is ideal for a 7" touch solution, as there is a border here of approx. 15 mm around the recess for gluing. The inside of the enclosure has several mounting options on 2 assembly levels. The displays and PCBs can thus be optionally mounted face up or face down. To ensure optimum operation, an enclosure canting kit for a 12 degree angle of inclination is available in the range of accessories. It contains two plastic brackets and is simply pushed into the existing groove in the base profile. Non-slip enclosure feet ensure reliable desk-top use. Alternatively, it can also be mounted flat on a wall using a wall suspension element. In addition to the covers made of plastic, aluminium panels are available to close the sides of the enclosures. The panel is mounted on the body of the enclosure using 4 screws. In this version, the three profile lengths are each increased by 4 mm.

The SMART-TERMINAL enclosures can be further modified by our own Service Center. The options include, among others, mechanical machining for interfaces, a customer-specific profile length, individual lettering and printing, or the manufacture and installation of digital printing foils. The areas of application include machine and plant engineering, safety engineering, building services engineering, measurement and control technology, environmental technology, agricultural vehicle technology, construction machines and embedded systems.
