4V210-08 DIN Connector Wiring: A Visual Guide

Wiring the Plug: 4V210-08 DIN Connector Explained

Most Airtac 4V210-08 valves use the standard DIN 43650C connector. Wiring this correctly ensures your PLC signals reach the coil without interference.

1. Terminal Identification

Inside the transparent plug, you will find three terminals. For DC24V models (4V210-08-B), Terminals 1 and 2 are used for the positive and negative leads. Terminal 3 (often marked with a ground symbol) must be connected to the machine's earth ground.

2. LED Polarity

If your 4V210-08 features an LED indicator, polarity matters for the light to function, even if the coil itself is non-polar. Always follow the '+' and '-' markings inside the connector housing to ensure the diagnostic LED works correctly during machine startup.
