Elma Electronic offers the Type 15i instrument case

nstrument enclosures are used in a myriad of industries and applica- tions. Designed to protect the important components housed within from external conditions, such enclosures will be built in a range of materials and sizes, and will offer features that will provide the best possible protection from whatever the final product will face. For example, an enclosure for a handheld measurement device may offer features that are different to a wall-mounted product or a device that is going to be permanently situated out- doors. Consideration therefore needs to be given to such factors as: Does the enclosure need to be lightweight? Is there the possibility that it might be dropped? Does it need to be impact resistant? Is it likely to be used in an environment where it will face chemical washdown or may it be situated, for instance, beside a railway track where it will need to withstand diverse weather condi- tions or perhaps even vandalism? Does it need to withstand extremes of temperature or might it be used in a position where it has to contend with vibration? The list is almost endless, and as a result companies


not only manufacture a wide range of standard prod- ucts, but many will also have the capability to customise solutions to meet specific application demands. As an example, Elma Electronic offers the Type 15i instrument case

that, it claims, is scalable in all three dimensions. This means it can be sized to house instruments or small portable devices such as: specialty test and measurement instruments; lab and field service instruments; medical devices like blood analysers; and specialty computers. The bottom, front and rear panel of these enclosures is manufactured from a single aluminium piece and they feature sturdy die-cast zinc corners that round off the edges. This sleek design is said to hide all the assembly hardware. According to the company, with its customisable dimensions, the

Type 15i uses proven tooled components to tailor the case to specific project requirements. Furthermore, the case offers design flexibility, including easy conversion from a desktop to a 19in rack-mount enclosure. As an option, the case can be EMC shielded.

Features to suit today’s applications Another solution is the NET-BOX range from OKW, which is available in three standard sizes from 140 x 140 x 45mm to 220 x 220 x 50mm. Described by the company as modern, sleek and attractive, these wall-mount enclosures are suitable for control and data applications such as data acquisition systems, central control units, measuring and

control equipment, data systems engineering and medical technology. This range has an inset cable connection panel which hides connectors under the removable front lid. Furthermore, they have a flat design which is said to give designers plenty of scope for installing electronics, assemblies, displays and large-volume connectors. Additional features include a curved top section which can be fitted with LEDs, displays and switches. An optional infill cover makes it possible to create an additional compartment for either greater installation volume, to protect the connection or to visually close the bottom part of the enclosure.

Robust and durable, the enclosures use UL 94 V-0 rated ASA+PC material, enabling use outdoors, and IP65 protection is available by specifying a sealing kit. Although designed as wall-mount cases, non-slip feet are available, enabling them to be used as desktop units. CamdenBoss, meanwhile, has launched a new range of desktop instrument and metal cases. Manufactured from moulded high impact ABS with epoxy coated steel for the lid and base, the desktop instrument cases are designed for test, measurement, display and control applications.

The enclosures feature functional push-fit construction for fast assem- bly, horizontal PCB guides in the side profiles, ventilation slots in the lid and base, front handles, and a choice of four non-slip feet or two non-slip and two tilting feet.

The company is also now offering 19in rack mount cases for electronic and telecommunications equipment being installed into 19in cabinets. These measure 260 x 360mm and are 1U, 2U and 3U high. Sturdy metal console cases are also available. According to the company, its latest desktop instrument cases and metal enclosures can be customised

to suit specific requirements, with options including milling, drilling, cutting and countersinking, custom colours and materials, surface coating and RFI shielding, plus much more.
