1971857-2

The 1971857-2 by TE Connectivity AMP Connectors revolutionizes Photovoltaic (Solar Panel) Connectors - Contacts technology for aerospace-grade power distribution systems. Designed to withstand extreme environmental conditions, this connector delivers unmatched signal integrity and EMI shielding performance for avionics applications. Its robust construction meets MIL-STD-810 standards while maintaining lightweight properties essential for airborne systems.Featuring Pin configuration with gold-plated contacts, this design ensures reliable connectivity in high-vibration environments. Compared to commercial-grade alternatives, the military-spec contacts maintain <2m resistance after 500+ mating cycles.Optimized for 10-12 AWG wiring, the crimp system provides strain relief capable of withstanding 50G shock loads. The patented contact geometry prevents fretting corrosion while maintaining impedance control across the entire flight envelope.The Crimp process utilizes cold-welding technology for gas-tight connections. This aerospace-proven method eliminates oxidation risks in low-pressure environments at high altitudes.With Tin plating, the contacts achieve superior performance in wide temperature ranges (-65 C to +200 C). The diffusion-barrier layer prevents intermetallic growth that could degrade signal transmission quality.
