Overview
Aitech’s E120 ¾ ATR-Short forced air-cooled enclosure is built to be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E120 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.

Sturdy Mechanical Design
The E120 is constructed of durable CNC machined 6061-T6 aluminum. Fasteners are stainless steel and removable cover threads have self-locking stainless steel helicoils to withstand severe vibration and shock. All I/O connectors are located on the front panel of the enclosure for easy access.
The chassis is forced air-cooled through a finned back wall and bulkhead.
Designed with a built-in handle, the E120 is also equipped with two front mounting hooks and two
rear hold-down pin receptacles to facilitate installation in standard ARINC 404 3/4-ATR mounting trays.
