The 97-3100A-14S(621)(0850) is a standard cylindrical wall mount receptacle from the Amphenol 97 Series, designed for durable, general-duty solder-type interconnections. It features a size 14S solid aluminum alloy shell with a non-RoHS black zinc alloy finish, a solid backshell, and a 7/8-20 coupling thread. This connector provides single key/keyway polarization, threaded coupling for secure mating, and non-rotating silver-plated contacts within a hard diallyl-phthalate dielectric insert. Designed for reliability, it operates over a temperature range of –55°C to +125°C and is intermateable with other 97 Series and SAE AS50151 connectors. Its cost-effective and field-proven design makes it suitable for a wide range of commercial applications, including robotics, machine tools, and industrial equipment.
