Product information

The measuring photoelectric sensor
combines the benefits of the triangulation
principle with the measuring functionality of a
distance sensor. The integrated measuring
principle enables a variety of switching
functions in one device, a large sensing
range up to 800 mm and a small BW/WB
difference up to the final detection range.
The sensor is equipped with an IO-Link
interface, through which the measuring
principle is optimized to the requirements of
the relevant application.

RL31-8-H-800-RT-IO/59/73c/136

Distance X [mm]

The detection range can be adjusted between 100 mm and 800 mm via the rotary switch or IO-Link. For finer adjustment, the
adjustable detection range is divided into several subranges which can be selected using Page Up/Down.

The value set with IO-Link is always assigned the current rotary switch configuration.

Setting using the rotary switch:

Increasing the detection range:
Turn the potentiometer to the right. If the desired detection range is not reached, turn the potentiometer to the right until it stops
(Page Up). The green LED will flash briefly. Now set the desired detection range again.

Reducing the detection range:
Turn the potentiometer to the left. If the desired detection range is not reached, turn the potentiometer to the left until it stops (Page
Down). The green LED will flash briefly. Now set the desired detection range again.

Example application: manually reduce detection range from 750 mm to 120 mm:

The potentiometer has a position as shown here, but works with a 750 mm detection range.

Now turn the potentiometer completely to the left until it stops (Page Down). The green LED will flash
briefly.

Now set the detection range to 120 mm. If the desired detection range cannot be set, turn the potentio­meter again to the left until it stops (Page Down) and repeat the procedure.

Setting via IO-Link interface

Setting different operating modes via IO-Link interface

The devices have an IO-Link interface as standard for diagnostic and parameterization tasks enabling optimum adaptation of the
sensors to the application. In addition, four different operating modes can be set:

Background suppression operating mode (1 or 2 switching points):

• Detection of objects irrespective of type and color in a defined sensing range. Objects in the background are reliably suppressed

• Background suppression with 2 switching points

active detection range

Background
suppression

Background evaluation operating mode:

• Detection of objects irrespective of type and color against a defined background. Reliable detection of objects at close range (detection
range >= 0 mm). The background serves as reference
