WSO26I: Align the sender with the receiver. Select the position so that the infrared light
(not visible) hits the receiver. The correct alignment can only be detected via the LEDs.
See table and table 5. The sender must have a clear view of the receiver, with no object
in the path of the beam. You must ensure that the optical openings (front screen) of the
sensors are completely clear.

WSE26 are through-beam photoelectric sensors that can be used at shorter distances,
in particular due to the large sensing range or the very high operating reserve.
Note application conditions: Adjust distance between sender and receiver with the
associated diagram [see table
If several through-beam photoelectric sensors which are installed next to one another
are to be used, we recommend swapping the sender/receiver arrangement at every
second through-beam photoelectric sensor and ensuring that there is sufficient dis‐
tance between the through-beam photoelectric sensors. By doing this, mutual interfer‐
ence can be prevented [see figure
NOTE TIP:
For some applications (e.g., when switching errors arise due to reflections), we recom‐
mend slightly misaligning the sender and receiver or significantly reducing the oper‐
ating reserve. The WSE26 can suppress switching errors under these conditions by
means of a teach-in (via IO-Link or using the Teach-in button on the housing). This
reduces the operating reserve at the same time.
