The E120 (see figure) can withstand extreme altitude, temperature, moisture, shock, vibration, EMI/RFI, and chemical exposure. This rugged, eight-slot, 3/4 ATR-Short chassis accommodates up to eight standard conduction-cooled 6U by 160-mm ANSI/IEEE 1101.2-1992 VMEbus or ANSI/VITA 30.1 CompactPCI modules, which are environmentally sealed within the chassis. It's well suited for aerospace and military environments, including ground vehicles and advanced tactical and strategic platforms.
The front panel features a flexible configuration of user-defined 38999-style connectors that conform to military standards—one for input power and the rest for I/O. Optional features include an elapsed-time meter, an LED indicator to track system operation, and an on/off switch or circuit breaker.
Two sealed, side-mounted heat exchangers supply external forced-air cooling, while the vehicle's environmental control system or an optional 28-V dc or 115-V ac fan supplies the cooling air. Design elements such as metal-to-metal clamping with conductive surfaces and fasteners with high-conductivity O-ring seals, filtered and screened power lines, and a shielded power-supply module all minimize EMI/RFI.

Enclosures The Senso-Case is designed for one-handed measuring, controlling, or signaling operations in a wide variety of applications. Users can grip the handle in their palm while operating pushbuttons with their thumb. The recessed control panel can hold membrane and silicone keyboards, pushbuttons, or display modules. Fastening pillars can be adjusted for the direct installation of printed-circuit boards and pushbuttons or displays. For standalone use, designers can fit the handle section with a battery holder for two AA batteries or a single 9-V battery. Or, they can opt for a strain relief for cable operation. For more information, go to www.okw.co.uk. The ElBox from Eldon Group features several improvements over the TEN and TED series that it replaces. The 400- and 500mm deep versions will ship as unassembled flat-packs, which will be easier to transport and store until needed. The 600-mm deep version will be pre-mounted at the factory. Both sides of the ElBox are removable, making component installation much easier. When the steel or glass door is closed, the side panels automatically lock in position, preventing unauthorized access to the contents. To learn more, check out www.eldon-enclosures.com. |
