Heavy Duty Male Coding Pin for Modular Inserts, Stainless Steel, Thread Size M3

The male coding pin is a mechanical coding element used in heavy duty connectors to prevent mismating between inserts. It is typically installed in the M3 threaded position on the female insert and works with a matching coding hole or recess. The male coding pin creates a unique mechanical coding pattern that ensures the connector mates only with the correct insert set during installation. This helps avoid incorrect connections in the field.

The coding pin is made of stainless steel. It provides stable structure and corrosion resistance for industrial environments. It does not carry electrical signals. Instead, it offers physical guidance and positioning for modular inserts and multi-position installations. When used with female inserts, coding blocks, or coding holes, it helps distinguish insert sets of the same size and improves system safety and maintenance efficiency.
