Photoelectric Sensors
Laser distance sensor with IO-Link and additional functions
BOD 21M-LBI05-S4
Installation (continued)
Fig. 3: Connector swivel range
The sensor can be attached in three different ways:
– Using two M4 screws and washers with the housing
through-holes
– Using a mounting bracket (available separately)
– Using special clamps (available separately) on the
dovetail of the housing
The switching distance is measured beginning at the
optical window.
The M12 connector can be rotated 270°.
Connections

Pin Signal
1 Supply voltage (+)
2 Analog output (Iout), switching output (Q2),
Reset input (In)
3 GND (–)
4 Switching output (Q1), IO-Link communication (C)
Tab. 1: Pin assignment
As shipped or after resetting the sensor to factory defaults
Pin 2 is configured as an analog output and Pin 4 as a
PNP switching output (Q1). The switching logic of Q1 is
normally open. The sensor uses background suppression
(see Section Factory setting on page 6).
Measuring accuracy
The sensor reaches its full accuracy after a minimum
switch-on time of 30 minutes under constant ambient
conditions.
The duration of warm-up depends on the ambient
conditions.

Indicators and operating elements
Fig. 5: Indicators and operating elements
Yellow LED function indicator for switching
output SSC1/Q1
LED on: Object is within set distance range
LED off: Object is outside set distance range
Switching output SSC2/Q2 is not displayed.
Green LED power and short-circuit indication
LED on: Power present, SIO mode
LED flashing (t :t = 10:1): IO-Link mode
on off
LED flashing (t :t = 1:1): Short-circuit on Pin 2/Pin 4
on off
LED off: Sensor not ready
Red LED error indication
LED on: Teach-In procedure not possible
Button
The button can be used to set switching point Q1 (SSC1)
as well as the start and end point of the analog output
(Iout).
Analog signal
The value of the analog signal depends on the distance
and the configuration of the analog output.
