Phoenix Contact 1662528 M12 4-Pin Straight Cable Connector

The Phoenix Contact 1662528 is a professional-grade M12 straight cable connector engineered for robust industrial automation and signal transmission. This 4-pin connector is designed for field assembly, offering a reliable and secure interface for data and power connectivity in complex technical environments. Built with high-quality materials, it ensures long-term stability and protection against mechanical stress.

Advantages

This connector features a durable zinc die-cast housing with a nickel-plated finish, providing excellent resistance to corrosion and environmental factors. The screw connection technology allows for quick and efficient installation without the need for specialized crimping tools, making it ideal for on-site maintenance and system integration. Its A-coded design ensures compatibility with standard industrial sensors and actuators, while the integrated cable gland provides a tight seal for cables ranging from 4 mm to 6 mm in diameter.

Suitable for

• Industrial automation systems
• Sensor and actuator connectivity
• Field-assembled signal transmission
• Machine building and robotics

When it may not be suitable

This connector is not intended for high-speed data transmission applications requiring shielded cables or specific Ethernet protocols. It is also not suitable for environments where cable diameters fall outside the specified 4 mm to 6 mm range or for applications requiring specialized quick-lock mechanisms.

Key specifications

• Connector type: M12 plug, straight
• Number of positions: 4
• Coding: A-coded
• Connection method: Screw connection
• Knurl material: Zinc die-cast, nickel-plated
• Cable gland: Pg7
• External cable diameter: 4 mm to 6 mm

How to use

To assemble the connector, strip the cable insulation to the appropriate length and insert the individual wires into the screw terminals according to the pin assignment. Ensure the wires are securely fastened. Slide the cable through the Pg7 gland and housing components. Tighten the cable gland to secure the cable and provide strain relief, then screw the connector housing together to complete the assembly.

What to consider before purchase

• Verify the pin count matches your existing system requirements.
• Ensure the cable diameter is within the 4 mm to 6 mm range.
• Confirm that the A-coding is compatible with your specific sensor or actuator interface.

Usage recommendations

Always ensure that the cable gland is tightened sufficiently to maintain the integrity of the connection and prevent moisture or dust ingress. Regularly inspect the screw terminals during maintenance cycles to ensure they remain tight and free from vibration-induced loosening.
