Aitech E119

Introduction

Aitech's E119 convection-cooled Dual Slot VME computer enclosure is built to be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E119 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.

Sturdy Mechanical Design

The E119 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 one side of the enclosure for easy access. Sides and top walls are externally finned for radiation and convection cooling.The bottom plate is smooth and flat for optional conduction cooling to cold plate.

The E119 is available in a shock-mounted configuration with two vibration helical wire rope type isolators to enhance vibration and shock survivability of the enclosure and its payload. There are two options to assemble the shock
mounts:

• Bottom assembly - suitable for applications with width limitations
• Side assembly - suitable for applications with height limitations

Also available are mounting brackets for hard mounted configuration suitable for cold plate applications.

The E119 accommodates two standard IEEE 1101.2 conduction-cooled VME cards.
