Network Cable METZ CONNECT 142MKA20100 M12 (R) No Connector 10m 5.7mm Unshielded A-coded Gray

The METZ CONNECT 142MKA20100 is a 10 m unshielded network cable with a 5.7 mm outer diameter, designed for industrial data transmission where a female M12 (A-coded) interface is required on one end and the other end is left without a connector for custom termination. The cable uses twisted pairs to support stable signal integrity over short to medium distances and is finished in a neutral gray jacket suitable for integration into control cabinets, machine installations, and structured cabling runs.

Advantages

This unshielded A-coded M12 cable offers straightforward installation when a factory-fitted connector is not needed on both ends, reducing connector cost and allowing field-specific termination. The 5.7 mm diameter balances flexibility and mechanical robustness, while the twisted pair construction helps mitigate crosstalk and maintain reliable data transfer in typical industrial environments. The gray jacket provides a discreet appearance and compatibility with standard industrial color schemes.

Suitable for

• Connecting sensors, actuators or devices with an A-coded female M12 interface to a custom-terminated cable harness
• Industrial automation and control systems requiring short to medium cable runs
• Applications where a pre-terminated connector on one end and field termination on the other is preferred
• Structured cabling inside control cabinets and machine enclosures

When it may not be suitable

This cable is unshielded, so it is not recommended for installations where strong electromagnetic interference (EMI) is present or where shielded cabling is required by system specifications. It is also supplied without a connector on one end, so it may not be suitable when both ends must be factory-terminated or when a specific connector type is required immediately out of the package.

Key specifications

• Length: 10 meters
• Outer diameter: 5.7 mm
• Coding: A-coded M12 interface on one end
• Shielding: Unshielded (no overall braid or foil)
• Conductor arrangement: Twisted pairs
• Color: Gray jacket

How to use

Install the cable by connecting the factory-fitted A-coded M12 connector to the mating female M12 port on the device. Terminate the open end according to your system requirements: strip the jacket to expose the twisted pairs, separate and prepare conductors, and apply the appropriate connector, terminal block or soldered connection following manufacturer wiring diagrams and safety practices. Secure the cable route to avoid mechanical strain and protect it from sharp edges, excessive bending, and heat sources.

What to consider before purchase

• Whether an unshielded cable meets the electromagnetic environment requirements of your installation
• That one end is supplied without a connector and will require field termination or an additional connector purchase
• Required conductor count and compatibility with your device pinout for A-coded M12
• Length and routing constraints in your installation space

Usage recommendations

For installations with potential EMI, consider using a shielded alternative. When performing field termination, follow precise stripping lengths and connector assembly instructions to ensure reliable contact and maintain data integrity. Use cable clamps or strain reliefs at termination points and avoid tight bends below the specified minimum bend radius to prolong cable life.
