The WTT12L is an opto-electronic photoelectric proximity sensor (referred to as "sensor"
in the following) for the optical, non-contact detection of objects. If the product is used
for any other purpose or modified in any way, any warranty claim against SICK AG shall
become void.
Test input: The WTT12L sensor features a test input ("TI" or "Test" on the connection
diagram [B]), which can be used to switch the sender off and therefore check that the
sensor is functioning correctly: If female cable connectors with LED indicators are used,
you must ensure that the TI is assigned accordingly.
There must be an object in the path of the beam (light reception); activate the test input
(see the connection diagram [B], TI 24 V). The send LED is shut down or no object being
detected is simulated. Refer to Graphics C to check the function. If the switching output
fails to behave in accordance with Graphic C, check application conditions. See section
Fault diagnosis.
The sensor can be used in standard I/O mode (SIO) or IO-Link mode (IOL). All auto‐
mation functions and other parameter settings are effective in IO-Link mode and in
standard I/O mode (exception: time stamp). Output of binary switching signals during
standard I/O operation via pin 4/black wire or via pin 5/gray wire.
Information on the IO-Link functions can be found in the enclosed IO-Link photoelectric
sensors operating instructions or downloaded from www.sick.com under the device
order number.
Check the application conditions: Adjust the sensing range and distance to the object
or background and the remission capability of the object according to the correspond‐
ing diagram [H] (x = sensing range, y = minimum distance between the object and
background in mm (object remission/background remission) (remission: 6% = black,
90% = white (based on standard white DIN 5033))).
The minimum distance (= y) for background suppression can be read from diagram [H
15] as follows:
Example: x = 1,000 mm, y = 20 mm. That is, the background is suppressed at a
distance of > 20 mm behind the object.
