Sick STR1 Safety Switch, Vistal

The STR1 RFID safety switch has monitored semiconductor outputs (OSSDs) and can be safely connected either individually or in series. It can be used for applications where a high level of manipulation protection is required. The STR1 is available with three codes. Universally coded sensors accept all actuators.

An actuator must be taught into both the uniquely coded and permanently coded variants

Response range of up to 14 mm
Small housing with flexible mounting options
Sensor activation possible from three sides
Four different actuators available
Universally coded, uniquely coded, and permanently coded sensors
PL e (EN ISO 13849), SIL3 (IEC 61508)
Safe series connection of up to 30 sensors possible

High level of flexibility when mounting the sensor and actuator
Reduced need for storage, as one sensor is suitable for a wide range of different applications
High level of manipulation protection due to individually coded actuator
High level of machine availability due to large door offset tolerance and high level of shock and vibration resistance
Economical solution due to series connection of up to 30 sensors
Fast diagnosis via LED status indicator
Long product service life due to low-wastage and low-maintenance configuration

Factory automation:
Monitoring of safety doors
Economic protection of assembly cells
Hazardous point protection on hydraulic presses
