2.1 Installing and Mounting the Sensor for Low Contrast Applications
Reliable transparent object detection depends on the sensor always detecting the object as "dark state" and the reflector
as the "light state". Using a recommended reflector, and proper orientation of the sensor to the reflector, is key to good
clear object detection. Optimize the reliable detection of transparent and clear objects by applying the following steps
when mounting the sensor and selecting a retroreflective target.
1. If a bracket is needed, mount the sensor onto the bracket.
2. Mount the sensor (or the sensor and the bracket) to the equipment at the desired location. Do not tighten at this
time.
3. Align the sensor's light spot to the middle of the retroreflector.
4. Mount the retroreflector perpendicular to the sensor optical axis (± 5°).
5. Tighten the screws to secure the sensor (or the sensor and the bracket) to the aligned position.
2.1 Mounting Considerations for Opaque Objects with Mirror Like Surfaces
To minimize the potential for reflections from mirror like objects affecting the sensor, it is best to side mount the sensor.

NOTE: NPN/PNP and Remote Input configurations are programmable using IO-Link.
NOTE: The remote input wire function needs to be enabled using IO-Link. The default for the remote input wire
function is Detection Output.
