The WT100-2 is an opto-electronic photoelectric proximity sensor for non-contact detection of objects, animals, and persons. Any other use voids the warranty.
Refer to the fault diagnosis table for troubleshooting. Common issues include:
Dispose of the sensor according to country-specific regulations, focusing on recycling materials.
SICK sensors are maintenance-free but recommend regular cleaning of lens surfaces and checking connections. No modifications should be made.
The sensor operates with a direct reflection detection system with background suppression. Reflectivity values are 6% for black, 18% for gray, and 90% for white, based on DIN 5033 standards.
After setup, the sensor is ready for use. Use diagrams to verify functionality. Refer to diagnostics if issues arise.
Troubleshooting measures for LED indicator patterns include:
Dispose of the sensor according to national regulations, focusing on recycling valuable materials.
Key parameters include a sensing range of 10 to 100 mm, with a maximum range of 4 to 140 mm. The supply voltage is DC 10 to 30 V, and the output current is 100 mA. The maximum switching frequency is 1,000 Hz, and the maximum response time is ≤ 0.5 ms. The enclosure rating is IP 67, and the protection class is III.
For optimal performance, increase the sensing range and maintain appropriate distance. Regular maintenance includes cleaning optical surfaces and checking connections.
Compliance with national disposal regulations is emphasized, advocating for recycling materials. Periodic checks are advised despite no regular maintenance requirement.
Environmental operating temperatures range from -25 to +55°C. Conditions for operation include a light/dark ratio of 1:1 and signal transit time with resistive load.

Open the catalog to page 3Sensor with potentiometer: The sensing range is adjusted with the potentiometer (type: 270°). Clockwise rotation: sen‐ sing range increased; counterclockwise rotation: sensing range reduced. We recommend placing the switching state in the object, e.g., see Graphic F. Once the sensing range has been adjusted, the object is removed from the path of the beam, which causes the back‐ ground to be suppressed and the switching output to change (see Graphic C). The sensor is adjusted and ready for operation. Refer to Graphics C and G to check the func‐ tion. If the switching output fails to behave in...
