HS3A non-contact, RFID-coded, safety interlock switches are ideal for applications where safety and reliability are of the utmost concern. By using unique RFID-coding for each actuator, these switches provide tamperproof security. Designed to be used in applications where no contact is desired between the switch and its actuating key, these Category 4 and PLe compliant, safety switches ensure detection of slow-moving, open, sliding and rattling doors by using RFID (radio frequency identification) signals to actuate the switch when in close proximity.
Multicode and unicode sensor heads are available, preventing tampering with the use of an unassigned spare actuator, and allowing installation in five directions. HS3A is designed for any application located in an area where a high level of tamper resistance and safety is required.
