Aitech E192 - Rugged/Military 3U cPCI/CompactPCI Enclosure/Chassis

Rugged/Mil Two-Slot, 3U CompactPCI Chassis for Harsh Environments


Aitech’s E192 cold plate cooled enclosure is built to  be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E192 is capable of withstanding extreme environmental conditions of altitude, temperature, moisture, shock, vibration, EMI and chemical exposure, making it ideal for use in military and aerospace environments.

Mechanical Design

The E192 chassis utilizes a bonded and fastened construction technique and is made of durable CNC machined 6061-T6 aluminum. Stepped corner joints enhance the structural and EMI integrity. All fasteners are stainless steel and removable panel threaded holes have self-locking stainless steel helicoils to withstand severe vibration and shock.

Board Capacity

The E192 accommodates 2 conduction-cooled 3U CompactPCI board per VITA 30.1-2002 with 0.8 inch pitch, and a 3U conduction-cooled power supply.

CompactPCI Backplane

The backplane is 3U CompactPCI compliant with J1 and J2 connectors in all slots. DC input power is routed to the power supply via a separate screened harness so as to prevent radiated or conducted EMI.

CoolingThe conduction-cooled, VITA30.1-2002 compliant boards are environmentally sealed within the chassis. The CompactPCI boards are positively clamped to the side walls of the chassis providing a direct thermal path to the base plate. The power supply’s DC to DC converters come in direct contact with the base plate.
IP/NMEAThe E192 is sealed against intrusion of external environment contaminants found in military applications, including: humidity, sand and dust, and contaminant splash. Enclosure mating surfaces are sealed with silicon rubber O-ring seals. Connectors and other accessories are protected also in the same manner.
