Easy integration with tamper-proof safety transponder
Sick 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. The STR1 can be installed individually or in series with up to 30 units, using T-junctions or the Sick Flexi Loop safety sensor cascade whilst still achieving PLe (EN ISO 13849) and SIL3 (IEC62061).
“Two big challenges with non-contact safety switches on removable guards are the mounting requirements and their susceptibility to tampering,” explains Sick UK safety specialist Dr Martin Kidman. To allow for exceptional flexibility during mounting, the STR1 has three different actuators, each of which can be actuated from four different mounting directions. With its compact Vistal housing, The STR1 offers outstanding mechanical stability, high EMC immunity and an IP67 enclosure, to ensure excellent reliability in harsh environments.
The versatility of the SICK STR1 Transponder Safety Switch makes it exceptionally easy to integrate. As it can be applied almost universally, it can reduce stocks of safety switches to a minimum.
