M40 Power Connector, Male & Female Heavy-Duty Power Plug, 40 mm Metric Thread, IP67/IP68 Waterproof for High-Power Servo Motors & Industrial Drives
What is M40 Connector
M40 connector is a metric circular connector with a 40mm external thread diameter. They are heavy-duty power products in the M-series connectors, designed specifically for heavy-duty applications.
Our M40 connectors are manufactured strictly according to the international standard DIN EN 61984, ensuring seamless compatibility with large industrial automation systems.
These connectors are designed to provide robust power to large servo motors, frequency converters, and heavy machinery, supporting high voltage and high current requirements while maintaining excellent signal integrity in the feedback system.
Advantages of M40 Connectors
- Massive Power Transmission
M40 connectors are capable of handling currents up to 55A and voltages up to 630V/800V, ideal for heavy-duty motor applications.
- Extreme Mechanical Durability
The oversized, robust metal structure is designed to resist extreme vibration, mechanical impact, and heavy cable strain.
- Optimized for Large Cables:
Specifically designed to accommodate large wire gauges required for high-current loads.
- Quick & Secure Locking
Features a high-precision threaded locking mechanism or Speedtec quick-lock compatibility to ensure a fail-safe connection in high-vibration environments.
