Courtesy: SICKThe STR1 transponder safety switch is designed to use 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 Flexi Loop safety sensor cascade. The transponder is also designed with three different actuators, each of which can be actuated from four different mounting directions. With its compact VISTAL housing, The STR1 high EMC immunity and an IP67 enclosure to ensure excellent reliability in harsh environments. The safety switch continually self-monitors its semiconductor output safety switching devices (OSSDs) to detect failures and has LED status indicators for fast diagnostics.
