High Quality IP65 Waterproof 4P 6-core M6/M7/M8 Cable Connector Plug for Male and Female Electric Bike Connectors
Product Overview
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.
Key Benefits
- Ultra-Compact Design: 6 mm max OD with coupling nut ≈6 mm, body length 25-30 mm, weight ~2 g (plastic) / ~5 g (metal)
- Superior Protection: IP67 standard / IP68 optional (mated) with silicone O-ring face, threaded M6×0.5 lock, and rear grommet
- Optimized Performance: 1-5 A / 250 V class rating, perfectly matched to 5/12/24 VDC sensor, LED strip, and e-bike signal loads
- Easy Installation: No soldering required with screw-terminal or IDC connections accepting 0.2-0.3 mm² (24-22 AWG) wire
- Premium Contacts: Gold-plated brass with ≤5 mΩ contact resistance, insulation ≥100 MΩ@500 V DC
- Secure Connection: Keyed/polarized inserts prevent reverse connection on DC LED and sensor lines
- Cost Effective: 30% smaller, lighter, and more affordable than M8 solderless connectors
