The MEC-2061 PC/104 1/4-Turn, Rail-Mount Enclosure offers a rugged packaging solution for PC/104 systems used in aviation, military and other demanding applications. Delivering NEMA rated environmental protection, ZS enclosures enable dependable rail/rack mounting within a standard 5.0" wide rack. They incorporate endcaps designed with Dzus® Fastener Quarter-Turn studs, which are commonly used in aircraft access panels. These kind of slide/push action "Zeus" fasteners provide exceptional vibration endurance, high strength fastening, and resistance to accidental opening. Mounting plate dimensions and fastener locations are in full accordance with Military Specification MS25212. This PC/104 enclosure enables a PC/104 Railed Card Cage fitted with Silastic ® Shock Rocks (shown below) to be placed inside for shock and vibration mitigation. Included in each enclosure kit, Railed Card Cages come in 4.0", 6.0" and 8.0" lengths to accommodate a 6.0", 8.0", and 10.0" chassis and hold up to 5, 8, and 11 PC/104 modules, respectively. See Railed Card Cage and Shock Rocks datasheets for more information. This enclosure series is the only enclosure specifically designed for PC/104 boards that uses the Quarter-Turn Dzus fastener rail system. Avionics electronics packages can now take advantage of the small, rugged, PC/104 footprint and gain full PC/AT functionality. Parvus also offers 3/4 ATR Enclosures designed for mounting in ARINC 404A avionics racks. Semi-custom enclosure designs tailored to specific customer requirements (i.e. connector cutouts) can also be accommodated in systems integration projects.
