Frequently Asked Questions

What are the proper mounting locations for this photoelectric switch?

Avoid dusty or corrosive gas environments, vibrating/shock areas, and proximity to strong-current circuits or induction sources.

How do I troubleshoot if the device is malfunctioning?

Check basic points like wiring connections, loose terminal set-screws, alignment/sensitivity adjustments, and ensure lenses are free of dirt. Also check for exposure to strong external light.

What are the power specifications?

The sensor requires a supply voltage between 12V to 24VAC, with a tolerance of plus or minus 10%.
