The 97-4102A-20-27P is an Amphenol 97 Series box receptacle connector featuring crimp-type rear release contacts for robust industrial applications. This connector utilizes stamped and formed crimp contacts with closed entry socket design and plastic retention, offering positive self-centering of contacts with pins bent up to 20° for reliable pickup. The connector operates at recommended DC voltages up to 700V and AC voltages up to 500V (Service Rating A), with wire size 20 AWG rated at 7.5 amperes. The solid shell construction is designed for open wiring and mounts directly on chassis, equipment, or panels with an integral polarized key in the front shell and threaded back shell for standard MS/AN fittings. This design provides reduced user cost through high-speed termination, greater contact-to-contact insulation, lighter weight, and higher reliability compared to solder-type alternatives, making it ideal for applications requiring fast, reliable connections without costly redesign or rework.
