The 97-3102A-18(621)(0850) is a box receptacle from the Amphenol 97 Series, designed with a solid shell for open wiring applications and direct mounting on chassis, equipment, or panels. It features a size 18 shell made from high-grade aluminum alloy with a non-RoHS black zinc alloy finish, threaded coupling (1-1/8-18 thread), and a single key/keyway for polarization. The connector utilizes hard diallyl-phthalate dielectric inserts for solder-type contacts and is rated for an operating temperature range of –55°C to +125°C. As a cost-effective and field-proven solution, it is intermateable with other 97 Series and SAE AS50151 connectors, making it suitable for general-duty industrial applications like robotics and machine tools.
