The M12A-04BFFB-SL7001 is a 4-pin M12 A-coded circular connector designed for sealed, waterproof connections in industrial environments. It features a screw-lock (SL) termination mechanism with a metal hex nut (16.0 mm hex) and thermoplastic housing in black, providing robust mechanical coupling. The connector employs copper alloy pins with gold plating for reliable electrical contact, an O-ring seal in gray rubber, and achieves IP67 waterproof rating when mated. The design includes a clamp ring and sealing nut, both thermoplastic black components, with overall dimensions of 47.0 mm reference length and 18.6 mm diameter. This connector is RoHS compliant and is commonly used in sensor networks, industrial automation, and field instrumentation where environmental sealing and reliable mating are critical.
