The Trident Series is a versatile range of environmentally resistant electrical connectors with fully interchangeable contacts. TNM (Trident Neptune Metal) is specifically designed to meet the needs of systems that require shielding, sealing, and the extra durability of a metal shell. The combination of Trident signal and power contacts, membrane seals, and the Universal Shielded end bell make TNM both cost effective and easy to assemble. TNM features nickel plated zinc alloy shells and UL 94 V-0 rated thermoplastic insulators. These connectors are UL approved.
