Electrical values
Input, teach-in (tch)
PNP: Teach = HIGH; Run = LOW
NPN: Teach = LOW; Run = HIGH
Input, all-teach-in (Atch), only for bus variants
PNP: Teach = HIGH; Run = LOW
NPN: Teach = LOW; Run = HIGH
Input, blanking input (bIn)
PNP: Blanked = HIGH; Free = LOW
NPN: Blanked = LOW; Free = HIGH
Input, light/dark (L--d)
PNP: Light switching = LOW; Dark switching = HIGH
NPN: Light switching = HIGH; Dark switching = LOW

Wiring the digital outputs
The number of digital outputs (open collector) available at the connections will vary,
depending on the device,
see "Pin assignment of the connections", page 16
. If the allo‐
cated event occurs in the read process, then the corresponding digital output is live.
In each case, the digital outputs are short-circuit protected and overcurrent protected.
Switching behavior: PNP
or
NPN
Electrical values
The sum current (100 mA) per sensor for all digital outputs is identical.
PNP/NPN residual voltage ≤ 1.8 V
Dielectric strength max 30 V
NOTE
When using sensors in bus operation, the sum current reduces as follows:
•
Up to 3 sensors = max. 100 mA
•
4-8 sensors = max. 50 mA
•
9-16 sensor = max. 20 mA

Connecting the supply voltage
NOTICE
Risk of damage to the device!
The device can become damaged if it is connected to a voltage supply that is already
switched on.
•
Only connect the device when the supply cable is de-energized.
The device must be connected to a power supply unit with the following properties:
•
Supply voltage DC 10.8 V – 26.4 V (SELV/PELV as per currently valid standards)
•
Electricity source with at least 3 W power
