Frequently Asked Questions – WLD4FP-213121A0ZZZ
Q1. What is the SICK WLD4FP-213121A0ZZZ?
It is a W4-series miniature photoelectric retro-reflective sensor used for non-contact object detection in industrial automation.
Q2. What is the maximum sensing range?
The maximum sensing range is 4.5 metres. The recommended range for optimal performance with the P250 reflector is 0.035 to 3.9 metres.
Q3. What is the operating voltage?
The specified supply voltage is 10–30 V DC.
Q4. Which type of light does the sensor use?
It uses a PinPoint LED that emits visible red light.
Q5. What is a retro-reflective sensor?
It emits light toward a reflector and receives the reflected light. When an object interrupts the light path, the sensor detects the change and switches its output.
Q6. Where can this sensor be used?
It can be used in conveyors, packaging machinery, assembly lines, and other industrial systems requiring object presence detection.
Q7. Where can I purchase this sensor in India?
Contact SICK India or an authorized industrial automation supplier to confirm availability, price, and delivery.
Q8. What should I check before purchasing?
Verify the complete model number, part number 1121472, operating range, P250 reflector compatibility, supply voltage, output type, and connector requirements.
