M6 M7 M8 Julet 2pin 3pin 4pin 5pin 6pin Male Female Quick Push Locking Mini Size E-motorcycle Battery IP65 Waterproof Connector
Product Overview
The M8 Waterproof Male-Female Connector is a compact industrial circular interconnect system featuring M8×1.0 threaded coupling and IEC 61076-2-104 compliance. This male-female pair creates sealed, keyed, vibration-resistant connections for 24 VDC sensors, IO-Link devices, photoelectric switches, valve coils, and D-coded 100 Mbps industrial Ethernet applications.
Key Benefits
- Ultra-Compact Design: 8mm maximum outer diameter fits where M12 connectors cannot, ideal for miniature applications and tightly packed sensor arrays
- Superior Protection: IP67 when mated (IP68 optional) with silicone O-ring, threaded lock, and rear grommet for dust, oil mist, and high-pressure washing resistance
- Versatile Compatibility: Handles 24 VDC 3-wire sensors, IO-Link (4-pin A), PROFIBUS (5-pin B), and compact PROFINET/EtherNet/IP nodes
- Secure Connection: Keyed A/B/D coding prevents incorrect mating and ensures proper electrical connections
- Durable Construction: Gold-plated brass/phosphor-bronze contacts, ≤5 mΩ resistance, ≥500 mating cycles, -25…80°C operating range
- Flexible Installation: Available as field-wireable or overmolded versions for easy customization and repair
- Cost-Effective: 33% smaller than M12 with 30-40% lower cost per mated pair
