Sensing range
WT34 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 (y) between the set sensing range (x) and the background should be
maintained.
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 6
1] as follows:
Example: x = 600 mm, y = 4.5 => 4.5% of 600 mm = 27 mm. That is, the background
is suppressed at a distance of > 627 mm from the sensor.
