643110-1 M12 Screw-Type Panel Connector (Series WR-CIRC)

The 643110-1 corresponds to the WR-CIRC M12 screw-mount circular connector family (panel solder bucket style) used for industrial sensor and I/O connections. These M12 connectors follow standardized coding (A, B, etc.) and provide secure, threaded mating for harsh environments. Panel-mount solder-bucket variants simplify cable assembly to PCB or panel, provide shielding and environmental protection, and typically operate in industrial temperature ranges. Verify exact coding (A/B), number of contacts, and pinout from the specific datasheet before design. Request the datasheet for mating dimensions and environmental sealing ratings.
