M19 Series 20A 10.4N Ultra Low Insertion Force Waterproof Power Connector Free Test Supported
M19 Series 20A 10.4N Ultra Low Insertion Force Waterproof Power Connector Free Test Supported
Product Definition
The M19 Series Power Connector is a robust, circular waterproof power connector designed for reliable power transmission in demanding environments. Available in male (plug) and female (socket) versions, it features a 3-pin + PE (protective earth) configuration, supporting up to 300V DC / 20A. With an IP-rated sealed design, threaded coupling, and high-grade materials, the M19 series delivers excellent waterproof, dustproof, and corrosion-resistant performance for industrial and outdoor applications.
Key Features
- High Power Capacity: Rated 300V DC / 20A – ideal for medium-power equipment
- Excellent Environmental Resistance: Operates in -25°C to +70°C with 90% humidity tolerance and passes 72-hour salt spray test
- Superior Safety & Reliability: AC2000V dielectric withstand voltage, ≥100MΩ insulation resistance, and low contact resistance (≤10mΩ)
- Secure Locking: Threaded coupling + spring-loaded design ensures vibration-proof and reliable connection
- Ultra Low Insertion Force: Only 10.40N — significantly easier to connect/disconnect than competitors
- Free Testing Service: We provide free sample testing, technical verification, and customized reports to support your project
