MultiPulse WTB4-3P (PNP: Load -> M)
Output oscillates at 2 Hz if an object is located within the fixed sensing range 30 mm ...
150 mm. Output switches off if an object is located within the range 0 mm ... 28 mm
and < 165 mm.
Align the sensor with the object. Select the position so that the red emitted light beam
hits the center of the object. You must ensure that the optical opening (front screen) of
the sensor is completely clear [see
We recommend making the adjustments using an object with a low remission.

WTB4-3P2100S79 are photoelectric proximity sensors with background suppression.
Depending on the remission of the object to be detected, and perhaps the background
behind it, a minimum distance between the set sensing range and the background is to
be maintained.
Check the application conditions:
Adjust the sensing range and distance to the object and background and the remission
capability of the object according to the corresponding diagram (x = sensing range, y =
monitored area between the set sensing range and background blanking as a % of the
sensing range (object remission/background remission)).
Remission: 6% = black 1, 18% = gray 2, 90% = white 3 (referring to standard white
as per DIN 5033).
We recommend that the adjustment be performed with an object of low remission.
The minimum distance (= y) for the background suppression can be determined from
the diagram [figure 8 1] as follows:
Example:
x = 100 mm
y = 7 => 7% of 100 mm
