The 348 Series connector provides reliability and high contact density. Qualified to MIL-C-81511, these connectors can accommodate a minimum of three circuits to a maximum of one hundred and fifty five circuits. 348 Series connectors are available in two basic constructions: Long (Series I) and Standard (Series II). The Series I features 100% scoop-proof construction (potential contact damage minimized by recessed pins). Series II, Standard connectors are scoop-proof when the pin contacts are specified in the receptacle shell only. Each construction, Series I and Series II, features a single one-piece molded dielectric retention system that locks the contacts in place. The contacts are crimp type, either power or shielded, and available in sizes 12, 16, 20 and 23-28 or 23-22 with wire size accommodations from 12 through 32 AWG. The 348 Series is a lightweight, compact connector offered in 4 shell styles: straight plug, square flange receptacle, single hole mounting receptacle and cable receptacle. It is environmentally resistant and will operate at sea level to a voltage of 600 VAC (RMS). It will perform under high temperature vibration, testing through 150°C.
