Aitech E193 - Rugged 3U cPCI/CompactPCI Enclosure/Chassis

Rugged/Mil Four-Slot, 3U CompactPCI Chassis for Mobile Military Applications

Introduction

Aitech’s E193 natural air, convection-cooled powered enclosure is built to be rugged and reliable as well as lightweight and compact. EMI/RFI protected and environmentally sealed, the E193 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 E193 is constructed of durable CNC machined 6061-T6 aluminum. Fasteners are stainless steel and removable cover screw 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 E193 is also equipped with two front mounting J hooks and two rear dagger pin hold-down receptacles to facilitate installation in ARINC 404 1/2-ATR mounting trays. 

Board Capacity

The E193 accommodates 4 conduction-cooled 3U CompactPCI board per VITA 30.1-2002 with 0.8 inch pitch, and a 3U conduction-cooled power supply. 

Compact PCI 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.

All I/O signals from the CompactPCI slots are routed via the backplane to wire-wrap posts that can be easily customized for specific applications.

CoolingThe conduction-cooled, VITA30.1-2002 compliant boards are environmentally sealed within the Chassis. The CompactPCI boards and power supply are positively clamped to the side walls of the chassis providing a direct thermal path to the mounting brackets.
IP/NMEAThe E193 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 aluminum filled fluorosilicon gaskets. Connectors and other accessories are protected also in the same manner.
