3 Product description
3.1 Intended use
The WTT12L-Axxxx is an opto-electronic photoelectric proximity sensor withanalog dis‐
tance value output (referred to as “sensor” in the following) forthe optical, non-contact
detection of objects. If the product is used for anyother purpose or modified in any way,
any warranty claim against SICK AGshall become void.

4.1 Check the application conditions:
Analog output:
Refer to Table Technical data and Diagram H3, H4 for the accuracy specifications of the
analog output.
Switching output:
Adjust the sensing range and distance to the object or background and the remission
capability of the object according to the corresponding diagram [H1, H2] (x = sensing
range, y = minimum distance between the object and background in mm (object
remission / background remission)). Remission: 6% = black, 90% = white (referring to
standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be read from diagram
[H1
1
] as follows:
Example: x = 1,000 mm, y = 25 mm. That is, the background is suppressed at a
distance of > 25 mm from the sensor.
