Non-contact safety switches
STR1

Compact, safe, and flexible

Your Benefits

  • 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

Overview

Compact, safe, and flexible

The STR1 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 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; this is the only actuator that the STR1 then accepts.

The sensor has three active sensor surfaces. The actuator comes in four different sizes. This allows the STR1 to offer maximum mounting flexibility.

At a glance
  • 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

Advantages

The STR1 non-contact safety switch switches with extreme reliability

To keep system productivity as high as possible, safety switches should do one thing above all else: Switch reliably. No matter what is happening around them. That is why safety switches must be rugged so they can work reliably even in very challenging environments. It is also important that the sensor status can always be clearly identified.

Thanks to the IPX9K enclosure rating, a very high electromagnetic compatibility and the VISTAL® housing made of glass fiber-reinforced plastic, dirt, shocks, heat and cold are no problem for the STR1.

The status of the STR1 safety switch can be read off at any time thanks to the highly-visible LEDs — even in bright ambient light.

The STR1 safety switch supports the productivity of your machines with its reliability.

The compact STR1 transponder safety switch can be mounted and used flexibly.

With its high flexibility, the STR1 non-contact safety switch not only offers many mounting options, but also features maximum manipulation protection thanks to its RFID technology. Simply select a combination of the best actuator and the coding required for your application.

There are four different actuator designs: mini, compact, flat, standard

The STR1 safety switch features active sensor surfaces at the front and on both sides

There are three coding options available for individualized manipulation protection: Universal, unique and permanently coded

The STR1 transponder safety switch offers a wide range of application options. You can use it as required by the risk assessment and machine design.
