POLYRACK TECH GROUP develops rugged ATR chassis

Polyrack ATR

Cumberland, RI – POLYRACK TECHGROUP has developed an ATR system (Air Transportation Rack) for use in harsh mechanical, climatic, chemical and electrical environments. The rugged MIL ½ short ATR chassis is designed according to ARINC 404A and has five 3U slots with Open VPX profile. The chassis conforms to VITA 65 and operates at a data transfer rate of up to 10Gbit/s. Dip brazed, the casing offers a completely sealed environment and assists passive “conductive cooling” by conducting the heat effectively away from the board and power supply unit. Wedge locks secure the board into the rack and support thermal management. As a result, this method combines excellent performance with the highest level of protection against shock and vibration, strongly fluctuating operating temperatures, dust and liquids in accordance with IP67 and other rough conditions.

The rugged MIL ½ short ATR chassis series is fitted with conduction cooled power supply compliant with VITA 62; various AC and DC inputs are available. Due to its aluminium structure the casing is very light. Moreover, by selecting norm-compliant materials it is suitable for use at higher altitudes.

The standard model is available in 13 sizes and versions which all comply with the norm. They can be adjusted in size, function, features and performance depending on the criteria required. Furthermore, the system can be configured using CPCI, VME, VMEX and VPX backplanes as well as power supply units and I/O connection cards. The heavy-duty rugged MIL ½ short ATR chassis is constructed according to specifications on safety and defense technology and satisfies all applicable norms and standards, e.g. MIL-STD-810G, MIL-STD-461C and MIL-STD-704(B-F). Fields of applications include aerospace (e.g. airborne fighters, helicopters), the navy (e.g. shipboards), the transportation sector (e.g. land vehicles) and demanding applications in industry and telecommunications technology.
