Product Description
The M25 2-Pin Male-to-Female Waterproof DC Power Connector is engineered for high-current DC power transmission applications. Designed specifically for DC power supply systems, it serves as a reliable core component for outdoor and harsh-environment equipment requiring uninterrupted power, featuring excellent waterproof performance and consistent electrical conductivity.
Featuring a standardized M25 self-locking structure, this 2-pin connector ensures precise compatibility with corresponding circuit interfaces. The male-female plug-and-play design allows for quick assembly while maintaining secure connections with low contact resistance. With a maximum rated current of 50A, it meets the power demands of mid-to-high-power devices including new energy vehicle charging piles, outdoor communication base stations, industrial automation machinery, marine vessels, and solar photovoltaic systems.
Constructed from high-quality PVC material, the connector housing offers outstanding aging and corrosion resistance for long-term durability. Internal pin cores are made of high-purity brass with gold plating, reducing contact resistance, minimizing heat generation during power transmission, enhancing anti-oxidation performance, and extending product service life.
Combined with an IP67 waterproof rating and self-locking mechanism, the connector effectively prevents intrusion of rainwater, dust, and oil stains, ensuring stable operation in humid, dusty, or temporarily submerged environments while providing comprehensive safety protection for connected equipment.
