M25 5 Pin Self Locking Waterproof Power Connector 30A 300V IP67 Quick Lock Circular Plug
The Fast-Lock M25 Weatherproof Connector is a rugged circular power and signal interface featuring a 25 mm threaded coupling body with push-twist self-latching mechanism. Engineered for quick installation without tools, heat-shrink tubing, or junction enclosures, it occupies the medium-to-large tier in the fast-lock outdoor connector range.
The fast-lock bayonet coupling requires simple alignment, pressing inward, and a 30-60° rotation to securely lock in place. Available in field-terminable screw-clamp and solder-pot versions or pre-molded cable assemblies for immediate use.
- Rapid coupling in seconds with one-handed operation
- High power density: 50A/500V capacity in compact M25 form factor
- Genuine IP67/IP68 protection when coupled
- On-site cut-to-length capability with screw-terminal inserts
- Keyed polarization prevents misconnection
- Industrial-grade contacts with low resistance and high cycle life
- V0 flame rating and wide temperature range (-40°C to +105°C)
