1. Proper Use
This wenglor product has to be used according to the following functional principle:
Fiber Optic Cable Sensors
Both plastic fiber optic cables and glass fiber optic cables can be connected to fiber optic cable sensors. Uni-
versal reflex sensors can be used both with and without fiber optic cables. Fiber optic cable sensors analyze
the light reflected by the object. The output switches when an object reaches the selected range (detection) or
when the active light beam is interrupted (operating limits). Bright objects reflect more light than dark objects,
and can thus be recognized from greater distances. In barrier operation, the color of the object has no effect
on the range.
2. Safety Precautions
• This operating instruction is part of the product and must be kept during its entire service life.
• Read this operating instruction carefully before using the product.
• Installation, start-up and maintenance of this product has only to be carried out by trained personnel.
• Tampering with or modifying the product is not permissible.
• Protect the product against contamination during start-up.
• Not a safety component in accordance with the EU Machinery Directive.

3.5. Contamination Warning
The contamination warning (included with all ODX202 types) is indicated by means of a blinking red LED (02)
(with rotary switch in the Run position).
3.6. Contamination Output
The contamination output (included with ODX202P0107) functions as a normally closed contact and is
switched off if the Sensor is operated within an unreliable range.
Unreliable range: ontamination, misalignment

èSwitching Distance is increased
• Activate the minus button (25)
èSwitching Distance is reduced
The LEDs at the plus and minus buttons function like a light scale. The more brightly the respective button is
illuminated, the greater the sensing distance and vice versa.
The corresponding button blinks if maximum or minimum sensing distance has been selected.
• Set rotary selector switch (07) to Run
4.5. Setting Switching Distance with the Teach-In function
The ideal Switching Distance for the object to be recognized is selected automatically with the Teach-In function:
