(emission wavelength) Infrared light-emitting diode (855 nm) Red LED (660 nm) Infrared light-emitting diode (855 nm)Consume current Emitter 15 mA or less,

Receiver below 20 mA Below 30 mApower supply voltage 12 – 24 V dc Class 2 ± 10% ripple (pp) below 10%Control output NPN or PNP open collector outputLoad current – below 100 mA (26.4 V dc reference)Residual voltage – NPN: below 1.5 V, PNP: below 1.5 VAction mode ON when light enters / ON when light is blocked – switch toggleindicator lights ▪ Red LED: Action indicator light

▪ Green LED: Stabilization indicator

▪ Green LED: Floodlight power indicator ▪ Red LED: Action indicator light

▪ Green LED: Stabilization indicatorSelf-tuning haveSelf-tuning (AGC) The button is locked, and after more than 20 seconds of unstable light input, it switches to stable light input mode.Sensitivity adjustment Button B1 increases fine sensitivity, button B2 decreases fine sensitivity.Protection
