Use this non-contact safety switch from Schmersal to automate the locking of your guard doors. It's used to prevent access to hazardous equipment during operation, preventing injury to personnel and damage to machinery. The switch is tamperproof as it's coded using RFID (radio frequency identification) technology, meaning you can only use it with an actuator that has the same frequency. You can install this switch in areas where space is limited thanks to its compact dimensions of 91 (length) x 52 (width) x 30mm (depth).

This safety switch is made of a durable glass fibre-reinforced thermoplastic material that's resistant to impact and heat. This makes it a good choice for use in harsh industrial environments.
