Sensor Configuration for Individual Applications
WLL190T-2
Max. Teach-in
Teach-in to maximum sensitivity. Stable
object detection without background
effect.
1-point Teach-in
Teach-in  quick and easy for standard
applications.
2-point Teach-in
Exact switching threshold adjustment
at the object and of the environment.
Ideal for applications with small system
reserves.
Auto Teach-in
Fully automatic switching threshold ad-
justment of moving objects. Even falling
or tiny objects are reliably detected.
Zone Teach-in
This so-called window technology learns
the object within a definable bandwidth
of the switching threshold. Ideal for the
detection of marks, or simultaneous fore-
ground and background suppression.
Teach-in of transparent objects
Teach-in with minimum sensitivity, reliably
detecting glass, films or small objects
Fast and reliable programming menu driven and at the push
of a button: sensor properties and parameters are individually
determined directly on the sensor.
Universal or individual
application solutions.

Summary

Universal or individual application solutions

Max. Teach-in

Teach-in to maximum sensitivity. Stable object detection without background effect.

1-point Teach-in

Teach-in quick and easy for standard applications.

2-point Teach-in

Exact switching threshold adjustment at the object and of the environment.

Auto Teach-in

Fully automatic switching threshold adjustment of moving objects.

From monitoring to power control.

ASC - AUTOMATIC SENSITIVITY CONTROL

Adapting the switching threshold to compensate for contamination when detecting transparent objects.

APC - AUTOMATIC POWER CONTROL

Compensates the natural attenuation of the sender LED for constant sender power.

ADJUSTING THE LIGHT INTENSITY OF THE SENDER LED

Adjusts the sender LED power in three stages to prevent saturation.

Custom configuration: Utilising the entire functionality.

Switching mode

Configures the sensor's switching behavior (e.g., light/dark switching).

Response time

Sets the time duration for the sensor's response to detected objects.

Time delay setting

Configures various time delay functions like OFF delay or ON delay.

Automatic sensitivity correction

Adapts the measuring range for optimum resolution based on signal.
