Introducing the D41 Series High-Coded Safety Door Switch

05 July 2021

Reducing the risk of interlock devices being deactivated, for a safe and worry-free production site.

Prevent industrial accidents caused by human errors

Safety components perform their safety functions only when properly used.

Some industrial accidents were caused by tampering with interlocking devices used for safety guards, although they could have been prevented. As these accidents often become problems in many countries, there is an effort to standardize prevention of tampering. Many countries adopt EN ISO 14119:2013 that defines the measures required to minimize defeat of interlocking devices and is becoming the global standard.

Reducing the risk of defeating by using high-coded systems

Thanks to its built-in function to prevent deactivation in the switch itself, you can reduce the risk of defeating your protection guards. In the "high-coded" safety door switch, the combination of sensor and actuator is fixed by pairing with more than 1,000 variations available.
