The WTB9(M4)-3 is an opto-electronic photoelectric proximity sensor (referred to as
"sensor" in the following) for the optical, non-contact detection of objects, animals, and
persons. If the product is used for any other purpose or modified in any way, any war‐
ranty claim against SICK AG shall become void.
Photoelectric proximity sensor with background suppression.
1 Check the application conditions: Adjust the sensing range and distance to the ob‐
ject or background and the remission capability of the object according to the cor‐
responding diagram [H] (x = sensing range, y = transition range between the set
sensing range and suppression of the background as a % of the sensing range (ob‐
ject remission / background remission). Remission: 6% = black , 18% = grey ,
90% = white  (referring to standard white as per DIN 5033).
The minimum distance (= y) for background suppression can be determined from
diagram [H] as follows:
