Tamper-proof transponder
Published:  08 December, 2016

Sick.jpgSICK has announced it has launched the STR1, a Transponder Safety Switch that uses non-contact RFID technology to provide highly-reliable and tamper-proof personnel protection on removable guards to PLe/SIL3, with easy installation and safety system integration.

“Two big challenges with non-contact safety switches on removable guards are the mounting requirements and their susceptibility to tampering,” explains SICK’s UK safety specialist and FS engineer Dr Martin Kidman, “The SICK STR1 is highly resistant to tampering whether through accidental damage or deliberate attempts to manipulate or ‘defeat’ a switch for operational convenience , by offering a choice of universal, unique or permanent coding options and unidirectional mounting screws”.
