Product features



Intelligence automatic heating-defrost system

Electrical heating glass window embedded inside the light screen, when the light screen has low penetrability because of the rain or snow, the electrical heating system operates automatically. so as to defrost the window.

Receiving beam strength detection

4 levels of beam strength are set up, it is convenient for field installation and maintenance.

Diagnosis function

Diagnostic LEDs provide a simple means of monitoring sensor performance.


Two discrete outputs (Detection output and alarm output, NPN/PNP optional) .

Shielding function

Can automatically detect the failures of the emitter or the receiver and pollution state of the lens, it can still work in the state of failures, at the mean time send out warning instructions and alarm outputs.
