The M6 Waterproof Plug is the smallest member of the threaded circular connector family, built on an M6×0.5 (≈6 mm nut OD) coupling thread. Despite its compact size, it delivers IP67 (optional IP68) sealing and serves as the ideal micro interface for ultra-compact sensors, mini photoelectric switches, medical probes, e-bike/scooter signal lines, and small LED/decorative lighting applications where M8 connectors are too bulky.
Available as molded-with-cable pairs (PVC/PUR/TPE jacket) or field-assemblable screw/IDC plugs, with 2-6 pin configurations, gold-plated brass contacts, and PA66+GF or nickel-plated zinc shells.
