Product description
point. If the object passes the 2nd switch point, switching output 1 is switched off. If an object is moved towards
the sensor, switching output 2 is switched off for as long as an object is located between the end of the sensing
range and the 1st switch point. If the object passes the 1st switch point, switching output 2 is switched on (see
Fig. 5 for hysteresis function).
When used as a retro-reflective sensor switching output 2 is switched on. A narrow switch window near the reflec-
tor is taught. The behavior of the switching output 1 is inverted in relation to switching output 2 (see Fig. 5 for
retro-reflective sensors).
