Operation as a diffuse mode sensor
In diffuse mode the LEDs have the following indication functions:
LED indication
Meaning
yellow
Switching output 1 on
green
NO contact: Object within the sensing range, switching output 1 off
NC contact: Object within the teach-in range, switching output 1 off
off (only NO contact)
No object within the sensing range, switching output 1 off
Operation as a retro-reflective sensor
In retro-reflective mode the LEDs have the following indication functions:
LED indication
Meaning
yellow
Reflector present, switching output 1 on
green
Object between sensor and reflector, switching output 1 off
off
No object within the sensing range, switching output 1 off
Switching output 2 inverts the signal of switching output 1.
IO-Link operation
In IO-Link mode the LEDs have the following indication function:
