Product details
TE Connectivity AMP Connectors's 640862-3 delivers military-grade reliability in Card Edge Connectors - Edgeboard Connectors for unmanned systems. Developed for harsh environment operation, this connector survives extreme shock, vibration, and environmental exposure.The Non Specified - Single Edge compatible design features hermetic sealing. When subjected to MIL-STD-810H Method 512.6 procedures, it prevents moisture ingress at 20psi differential pressure.Female configuration includes positive locking. The bayonet coupling requires 15N m torque for disengagement, preventing accidental separation in flight.With 3 contacts per row, the connector achieves 40% weight reduction versus circular designs. The optimized layout maintains signal integrity up to 10Gbps.The 3 contact arrangement supports triple-redundant systems. Each critical signal path has three parallel contacts for fault tolerance.Compatible with 0.062" (1.57mm) rigid-flex boards, the connector features floating contacts. This design accommodates 0.8mm board warpage without compromising connection quality.The 1 row architecture includes EMP shielding. The continuous Faraday cage provides 80dB attenuation from 10kHz to 18GHz.0.156" (3.96mm) micro-pitch withstands 100G shock pulses. Finite element analysis confirms zero contact separation during MIL-STD-883 Method 2002 testing.Single capability supports battlefield diagnostics. The color-coded test points enable quick verification without specialized tools.The Free Hanging (In-Line) version includes vibration-resistant features. The tuned mass dampers reduce resonant amplification by 12dB at critical frequencies.IDC process creates cold-welded joints. The diffusion-bonded connections exhibit no intermetallic growth after 1000 thermal cycles.The Copper Alloy contacts survive sand/dust exposure. Testing per MIL-STD-810G Method 510.6 shows <1m resistance change after 50 hours abrasion.Tin-Lead plating provides lubricity in vacuum. The dry-film coating maintains <0.2 friction coefficient from sea level to 10-6 torr.With 80.0µin (2.03µm) plating, the contacts resist atomic oxygen erosion. Testing on MISSE-7 confirms <5nm material loss after 18 months LEO exposure.The White housing meets NATO camouflage requirements. The IR-reflective pigments maintain low observability in 3-5 m and 8-12 m bands.Rated for -55°C ~ 105°C, the connector survives rapid thermal cycling. Testing confirms 500 cycles between -65 C and 150 C with no performance degradation.
