The AP Labs FS-5971 is a 5-slot, conduction cooled chassis for Airborne and Vetronics applications.  It is capable of maintaining a sealed, dry air environment, while subject to humidity, immersion and exposure to fluids environments.  This allows you to use it in environments with extreme temperatures, shock, and EMI requirements where reliability is important.

Mounting & Cooling
The base structure of the chassis matches the physical outline limits defined in the ARINC 404A^TM specification for a  ¹/₂ ATR, short box.  Cooling is achieved utilizing internal conduction to the chassis side plates, whereby the heat is rejected via natural convection.  The FS-5971 provides a secure enclosure for conduction cooled cards over a wide ambient temperature range.  The environmental specification defined in the adjacent table indicate the upper temperature limits for a given
thermal load.
