Quick Lock M25 Waterproof Plug Connector New Energy Li Ion Battery Energy Storage Connector

The Quick-Lock M25 Waterproof Plug is a heavy-duty circular power/signal connector featuring a 25 mm (M25×1.5 / PG25-class) threaded coupling body with a push-turn or spring self-locking mechanism that seats and seals in seconds—requiring no wrench, heat shrink, or junction box.

As the mid-large size in the quick-lock outdoor connector family, it sits above M12/M16/M20 and below M32, purpose-designed for branch-grade power feeds, battery/inverter interfaces, LED trunk lines, and machine power entries where 30-50 A carry capacity, IP67/IP68 sealing, and tool-light field assembly are required.

The "Quick-Lock" bayonet/push-lock coupling nut enables fast operation: align the keyway, push in, twist 30-60°, and it clicks locked with anti-vibration retention. To release, simply pull back the sleeve or twist reverse. Available in field-wireable screw-terminal and solder-cup versions for raw cable through the rear gland, or pre-assembled molded-with-cable versions for plug-and-play convenience.
