Safety Sensor

guard door closure. These sensors use noncontact operating principles that limits wear on components, and tolerates misalignment. A microprocessor provides continuous internal function tests and monitors the safety outputs, meeting PLe to ISO13849-1 and SIL 3 to IEC61508, even when wired in series. Three color LEDs on the sensor indicate status, various errors, and misalignment. For more advanced indication these models are also available with serial diagnostics to connect to commercial field bus systems.

Electronic safety sensors are used to detect guard door closure. These sensors use noncontact operating principles (pulse echo) that limits wear on components, and tolerates misalignment. A microprocessor provides continuous internal function tests and monitors the safety outputs, meeting PLe to ISO13849-1 and SIL 3 to IEC61508, even when wired in series. Three color LEDs on the sensor indicate status, various errors, and misalignment. For more advanced indication these models are also available with serial diagnostics to connect to commercial field bus systems.

 Magnetic safety sensors are of particular advantage in cases where extremely dirty conditions can occur or high hygienic standards need to be maintained. This is provided by the simplicity of cleaning the units.

These switches are available in a variety of profiles and housing materials, including IP69K rated models.
