Aitech E106

Designed for Harsh Mechanical, Climatic, Chemical and Electrical Stresses

Manufacturer: Aitech
Aitech E106

Aitech's E106 Fan-cooled VME computer enclosure is built to be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E106 is capable of withstanding extreme environmental conditions of altitude, temperature, humidity, shock, vibration, EMI and chemical exposure. This makes it ideal for use in all military environments.


The E106 is constructed of durable CNC machined 6061-T6 aluminium. Fasteners are stainless steel and often-used threads have self-locking stainless steel helicoils to withstand severe vibration and
shock. All connectors are located on the front panel of the enclosure for easy access. Side and back walls are internally finned (to create air tunnels), for cooling by the forced air from the integral fan.

Designed with a built-in handle, the E106 is also equipped with hooks and mounting holes to facilitate installation in standard 1/2-ATR short mounting trays.

The enclosure is also available with optional mounting brackets for base plate hard mounting.


The E103 accommodates 3 standard VME boards with 0.8-inch pitch, including:

• IEEE 1101.2 conduction-cooled VME cards
• Commercial VME boards without front panels 


The 3-slot backplane is VME64x compliant with 160-pin, 5-row J1/J2 connectors and 95-pin PO connectors in all slots and automatic Daisy Chain.

Any of the pins in rows A and C, and user-defined pins in rows Z and D of the J2 connectors, as well as the 95 I/O pins from each of the P0 connectors (up to a maximum of 512), can be routed to front panel I/O connectors.

The backplane also contains two I2C devices with integrated temperature sensors and voltage monitors. An additional I2C device is an Elapsed Time Recorder (ETR) that stores the cumulative operating
time of the enclosure. System temperature, backplane voltages, and total elapsed operating time of the enclosure can be read by the system SBC via its I2C bus, if available.

CoolingThe E106 does not require external forced-air or base plate cooling. Thermal design of the enclosure is based on internal heat conduction and external forced convection. The boards and power supply in the enclosure are cooled by conducting their heat to the enclosure interior sidewalls. External cooling is accomplished by means of the system fan blowing cooling air through shrouded heat exchangers on the exterior sidewalls of the enclosure. Heat conducted from the boards and power supply inside the chassis is conducted through the aluminium sidewalls from which it is carried away by the cooling air.

The fan is temperature-controlled and operates when the enclosure temperature exceeds the point of self- sustained heat dissipation.
IP/NMEAThe E106 is sealed against humidity and splash. Enclosure mating surfaces are sealed with hollow fluorosilicone rubber seals. Connectors and other accessories are protected in the same manner.
