Aitech's E111 forced air-cooled VME computer enclosure is built to be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E111 is capable of withstanding extreme environmental conditions of altitude, temperature, moisture, shock, vibration, EMI and chemical exposure. This makes it ideal for use in all military environments.
Sturdy Mechanical Design
The E111 is constructed of durable CNC machined 6061-T6 aluminum. Fasteners are stainless steel and often-used threads have selflocking stainless steel helicoils to withstand severe vibration and shock. All connectors are
located on the front panel of the enclosure for easy access. Sidewalls are internally finned for forced air-cooling without sacrificing ruggedness. Designed with a built-in handle, the E111 is also equipped with hooks and mounting holes to facilitate installation in standard ATR mounting trays.
The E111 accommodates 15 standard VME boards with 0.8 inch pitch, including:
- IEEE 1101.2 conduction-cooled VME cards
- Commercial VME boards without front panels VME Backplane
The backplane assembly is a multilayer printedcircuit board, supporting A32/D32 connectivity in accordance with ANSI/IEEE 1014-1987. DC input power is routed to the power supply via a separate screened harness so as to prevent EMI.
96-pin J1 and J2 board connectors meet VMEbus standards. Rows A and C of the J2 connectors are routed to front panel connectors to support I/O functions. Backplane options include protection transzorbs on each I/O line.
