Frequently Asked Questions
Get quick answers to common technical queries regarding our laser sensing solutions.
How do I align the laser emitter and receiver over long distances?
Our sensors use a Class 1 visible red laser beam. To align, power both units and adjust the angles until the red spot hits the center of the receiver lens. The built-in signal indicator will turn green once the optical axis is perfectly aligned.
What is the smallest object size it can detect?
Due to the high-collimation of the laser, our standard series can detect objects as small as ø 1.0mm. For micro-parts, our precision series can detect targets down to ø 0.5mm, such as thin wires or micro-electronics.
Will dust or oil mist affect the sensing performance?
While dust can attenuate signals, our high-power laser diodes have excellent penetration. For harsh environments, we recommend IP67/IP68 rated models and periodically cleaning the lens to ensure consistent uptime.
Should I choose NPN or PNP output for my PLC?
This depends on your PLC's input logic. NPN (Sinking) is common in Asia, while PNP (Sourcing) is the standard in Europe and the US. Most XSZ sensors are available in both versions or universal NO/NC selection.
What is the expected service life of these sensors?
Under standard industrial conditions, our laser diodes have a service life of over 50,000 hours. Combined with rugged metal housing, they are designed for long-term reliability in 24/7 automation lines.
