IDEM's RFID Coded Non-Contact Switches (Uniquely Coded)
IDEM's RFID Non-Contact Coded Switches have been developed to provide and maintain a high level of functional safety whilst providing a very high anti-tamper coded activation. Coding is achieved by using magnetic and radio frequency techniques, both principles need to be satisfied for the switch to operate safely. They will connect to most popular standard Safety Relays to achieve up to PLe/Category 4 to ISO 13849-1.
They are offered in high specification plastic housings and can be used in almost any environments including high pressure cleaning following contamination from foreign particles. They have IP69K ingress protection and are suitable for CIP and SIP cleaning processes. The typical sensing distance "on" is 14mm with wide tolerance to guard misalignment after setting. The RFID sensing provides a tamper resistant operation when the actuator is in the sensing range of the switch.
