Sensor Confi guration for Individual Applications

MANUAL

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 ad­justment of moving objects. Even falling
or tiny objects are reliably detected.

Zone Teach-in

This so-called window technology learns
the object within a defi nable bandwidth
of the switching threshold. Ideal for the
detection of marks, or simultaneous
foreground and background suppression.

Teach-in of transparent objects

Teach-in with minimum sensitivity, reli­ably detecting glass, fi lms or small
objects.

Universal or individual –
application solutions.

Fast and reliable programming, menu driven and at the push
of a button: sensor properties and parameters are individually
programmed directly on the sensor.
Teach-in or manual adjustment? You decide!

Photoelectric sensor for fi ber-optic cables
WLL180T – Easy handling, structured functions
and optimum functionality.

The photoelectric sensor for fi ber-optic cables WLL180T with the SICK fi ber-optic
cables of the LL3 series is especially suited to detecting very small objects,
objects in front of refl ective backgrounds, and transparent and moving objects.
Fiber-optic cables are ideal for use in installations where space is restricted.

2X4-DIGIT NUMERIC DISPLAY

Dual 7-segment display for simultaneously showing nomi­nal/actual values and for interactive operator guidance.

ASC –
AUTOMATIC SENSITIVITY CONTROL

For instance, automatically adapting the switching
threshold to compensate for contamination when
detecting transparent objects.

SHORTEST RESPONSE TIME

Detection of fast processes is an easy task for the
worlds fastest photoelectric fiber-optic sensor. With a
response time of only 16 μs objects can be detected
precisely. A small jitter contributes to the accuracy of
the detection.

Smallest changes in the level of the received light are
already sufficient for a reliable detection.

HIGH RESOLUTION SIGNAL PROCESSING

The power of the sender LED can be adjusted in three
stages: saturation, e. g. in case of highly reflective
objects, is prevented.

ADJUSTING THE LIGHT INTENSITY
OF THE SENDER LED

From monitoring to power control.

Monitoring simplifies many things, and technical highlights
provide many options, always enabling easy commissioning
and permanently reliable operation.
