FAQ
Q: What advantages does polarizing retro-reflective type bring?
A: It adopts polarizing filter design, which can suppress false detection caused by highlyreflective target surfaces and works well for shiny workpiece measurement.
Q: What benefits can multiple output types bring for system integration?
A: NPN transistor output fits high-speed PLC signal acquisition; relay contact output supports direct drive of heavyload equipment, bringing great convenience for different control system matching.
Q: Why is high anti-ambient-light performance important for real projects?
A: It can resist up to 30000lx incandescent light interference, avoiding abnormal signal fluctuation from factory workshop lighting and improving overall equipment operation reliability.
