WS Series Aviation Connectors
M13 Circular Connector - 6 Pin Industrial Waterproof Plug and Socket
The M13 Series Circular Connector is a compact interconnect solution designed for demanding industrial environments. Featuring a robust threaded locking mechanism, this 6-pin connector ensures a secure, vibration-proof connection for sensors, actuators, and data transmission systems. Often selected for its precise 13mm mounting size, the M13 bridges the gap between M12 and larger aviation plugs, offering a balance of space-saving design and electrical reliability.
Key Features and Selection Considerations
When evaluating the M13 connector for your application, consider the following decision points:
-
Secure Threaded Locking: Precision-engineered M13*1.0 threads prevent accidental disconnection in high-vibration machinery.
-
IP67 Waterproof Rating: Equipped with high-quality O-rings to protect against dust and temporary immersion in water, making it suitable for harsh outdoor or factory floor conditions.
-
Compact 6-Pin Configuration: Optimized for multi-signal transmission or low-voltage power supply in tight spaces.
-
Durable Cycle Life: Rated for over 500 mating cycles without mechanical or electrical degradation.
Material Construction and Application Fit
The M13 connector is built with premium materials to ensure long-term performance. The housing is available in high-grade nickel-plated brass or rugged polymer for corrosion resistance, while the contacts use gold-plated copper alloy for superior conductivity and minimal signal loss. This construction makes the connector well-suited for sensor systems, actuators, and industrial data transmission where space is limited but reliability is critical.

Application Boundaries
The M13 connector is ideal for applications requiring a compact, waterproof interconnect with moderate pin counts. However, it is not intended for high-current power distribution or applications requiring more than 8 pins. For higher pin counts or different mounting requirements, consider the Aviation Plug Connectors series, which offers a broader range of configurations.
Inquiry Checklist
To ensure the correct M13 connector configuration for your project, please provide the following details when inquiring:
- Required pin count (2-8 pins) and gender (male/female)
- Mating-side requirement and pinout or drawing
- Cable outside diameter and conductor size
- Electrical load (current and voltage)
- Environmental conditions (temperature, exposure to chemicals or water)
- Order quantity and preferred termination method
