Aitech E107 - 1/2-ATR Short VME Enclosure

5 Slot VME64 Compliant Rugged Computer Enclosure, Specially Designed for Space Applications

Introduction

The Aitech E107 is a cold plate cooled 5-slot VME64 compliant rugged computer enclosure, specially designed for space applications. Up to three drop-in power supplies can be installed to provide redundancy in highly critical operations. The power supplies operate in a load-sharing configuration to minimize stress and increase longevity. In case of power supply failure, the remaining power supplies take up the load to ensure uninterrupted operation. 

The E107 features extended height to accommodate fiber optic cables.

Sturdy Mechanical Design

The design of the E107 has been optimized to provide maximum strength with minimum weight. Constructed of durable CNC machined 6061-T6 aluminum, the chassis is assembled using stainless steel fasteners to prevent corrosion. 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. All external surfaces, with the exception of the cold plate interface, are hard anodized coated for excellent corrosion resistance. The cold platemating surface is precision machined to ensure excellent heat transfer to the cold plate, and it is configurable to meet any customer-mounting requirements.

Board Capacity

The E107 accommodates 5 standard VME/VME64 boards with 0.8 inch pitch, including:

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