RFID Non-Contact Safety Interlock Switch
RFID-coded non-contact safety interlock switches - the modern replacement for mechanical safety switches. Highest manipulation protection, wear-free operation. Schmersal CSS, Omron D40Z, Allen-Bradley SensaGuard, Pilz PSENcs supplied in India.
RFID CodedManipulation ProofWear-FreePL e / SIL 3
RFID coded safety switches use a unique code exchange between actuator and sensor - impossible to defeat with a spare key or magnet. Highly recommended for new machinery designs.
Why RFID?
- Highest manipulation protection (fully coded).
- No mechanical contact - zero wear.
- Tolerant of door misalignment.
- Compact, sealed body suits washdown.
- Simple wiring to safety relay / safety PLC.

FAQ
Can I daisy-chain RFID switches?
Yes, most modern RFID switches allow series connection while maintaining PL e / SIL 3.
Do RFID switches also lock the door?
No, RFID sensors detect only. For locking, combine with a mechanical solenoid interlock or use models like PSENslock.
