Amphenol Aerospace Tri-Power Connectors

Amphenol Aerospace Tri-Power Connectors combine the reliability of MIL-DTL-38999 III Tri-Start Connectors with high-current RADSOK and Temper-Grip contacts. Amphenol Aerospace Tri-Power Connectors enable users to choose contacts ranging from 70A to 250A per contact (240A to 1000A per connector). The series enables more current-carrying capability than comparably-sized MIL-DTL-5015 and MIL-DTL-22992 connectors. Tri-Power Connectors with RADSOK offer low contact engagement / separation force, low contact resistance, and silver-plated contacts. Tri-Power Connectors with Temper-Grip handle up to +200°C with no decrease in performance and provide gold-plated contacts.
