50A Waterproof IP67 Connectors M25 4 Pin Wire To Wire Power Connector
The M25 4Pin 50A industrial waterproof power connector adopts an integrated molded cable structure, which effectively enhances overall tightness and structural stability compared with traditional assembled connectors. Designed with a 4-pin integrated conductive layout, it supports continuous and stable 50A high-current transmission for industrial high-power outdoor power supply scenarios.
Quick Details of IP67 Waterproof Connector
50A High Current Capacity for Stable Industrial Power Supply: Equipped with thickened high-purity copper conductive pins and a standardized 4-pin layout, the connector features low conductive loss and low heat generation. It supports long-term stable 50A high-current output without voltage drop or overheating, fully meeting the continuous power supply requirements of various industrial high-power equipment.
Integrated Molded Construction for Superior Tensile & Bending Resistance: The cable and connector are integrally molded in one piece with seamless connection, completely avoiding cracking, wire loosening and water leakage common in spliced connectors. The flexible molded cable resists frequent bending and pulling, maintaining structural integrity and extending service life in complex working conditions.
IP67 Full Sealing Protection for All-Weather Industrial Use: Adopting multi-layer composite sealing and integral molding technology, the connector achieves full-range tight protection. It effectively blocks rainwater, dust, moisture and oil contamination from entering internal circuits, preventing electrical failures in open-air operation, humid workshops and harsh outdoor equipment cabins.
Industrial-Grade Weather & Aging Resistance: The tough flame-retardant engineering housing delivers excellent impact resistance, compression resistance and wide-temperature tolerance from -40℃ to +105℃. It features outstanding UV resistance, anti-aging and anti-corrosion performance, adapting to long-term outdoor exposure, rain, snow and salt spray environments.
