Adapter Harting 21033812401 4-polet lige stik

Harting adapter 21033812401 is a 4-pole straight connector intended for reliable electrical connections in industrial and automation environments. The compact straight configuration contains four contact positions suitable for signal or low-power circuits. Designed for use where a durable, space-efficient 4-contact interface is required, the adapter supports straightforward mating with compatible counterparts and can be integrated into panel or cable-mounted assemblies.

Advantages

The adapter provides a compact footprint and a robust mechanical design that helps maintain stable electrical contact in demanding conditions. Its four-contact arrangement simplifies wiring of small control and signal circuits while minimizing cable bulk. The straight configuration makes alignment and installation straightforward in confined spaces, and the construction is engineered for repeated mating cycles and long service life.

Key specifications

• Configuration: 4 contact positions in a straight connector layout
• Application: signal and low-power circuits, industrial automation
• Mounting: suitable for panel or cable mounting arrangements
• Contact style: durable mating contacts designed for multiple mating cycles
• Size: compact straight-body design for space-constrained installations

How to use

Install the adapter by aligning the straight connector with the mating counterpart and engaging until contacts are fully seated. For panel mounting, secure the body according to the panel cutout and fixation method used in the assembly. Ensure conductors are terminated to the appropriate contact positions using compatible crimp or screw terminations as specified by the connector family, and verify polarity and wiring continuity before applying power. Follow standard safety procedures and de-energize circuits during installation.

Recommendations

Use the adapter for signal-level and low-power connections where a compact, reliable 4-contact interface is required. Avoid exceeding the intended current and voltage ratings for signal circuits; consult system documentation for environmental protection requirements. Inspect mating contacts periodically for wear or corrosion and replace the connector if contact resistance increases or mechanical retention degrades.
