Overview
\nAitech\u2019s E121 3\/4-ATR Short air-cooled enclosure is built to be rugged and reliable as well as lightweight
\nand compact. EMI\/RFI protected and environmentally sealed, the E121 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.<\/p>\n

Sturdy Mechanical Design
\nThe E121 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 air-cooled. Designed with a built-in handle, the E121 is also equipped with two front mounting hooks and two rear holddown pin receptacles to facilitate installation in standard ARINC 404 3\/4-ATR mounting trays.<\/p>\n","protected":false},"excerpt":{"rendered":"
