The SICK´s STR 1 transponder 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 STR 1 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; this is the only actuator that the STR 1 then accepts. The sensor has three active sensor surfaces. The actuator comes in three different sizes. This allows the STR 1 to offer maximum mounting flexibility.

Features

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

Advantages

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.
