Serial Cable Harting 21 03 371 1405

The Harting 21 03 371 1405 serial cable is a compact 0.5 m communication cable designed for industrial and automation environments. It combines black, blue, grey and white sheath colors and features an M12 connector for secure serial data connections. The cable is RoHS compliant and has a low weight of 32.33 g, making it easy to route and install in confined spaces where stable serial communication is required.

Advantages

This serial cable offers a short, robust connection with an M12 connector that ensures reliable mating in vibration-prone settings. The compact 0.5 m length reduces signal attenuation and clutter in control cabinets and machine tool enclosures. RoHS conformity limits hazardous substances, supporting regulatory compliance. The lightweight construction simplifies handling during installation and maintenance.

Suitable for

• Point-to-point serial connections between controllers and field devices
• Sensor and actuator wiring in compact industrial panels
• Temporary test setups and bench connections in automation labs
• Space-constrained installations where a short reliable cable is required

Key specifications

• Cable length: 0.5 m
• Connector type: M12
• Colors: black, blue, grey, white
• Compliance: RoHS
• Weight: 32.33 g

How to use

Connect the M12 connector to the corresponding M12 serial port on the device, ensuring correct alignment and secure engagement. Route the cable to avoid sharp edges and excessive bending radii; maintain gentle curves and secure the cable with appropriate clamps or ties if required. For signal integrity, avoid running the cable in parallel with high-voltage power lines where possible. Inspect connectors for contamination before mating and replace the cable if mechanical damage is visible.

Recommendations

Use the cable for short-distance serial links within control cabinets, machinery enclosures or test benches. Store the cable coiled without sharp bends and protect connectors from moisture and dust when not in use. For long-term installations in harsh environments, verify connector sealing and consider compatible mating connectors or protective boots.
