As more and more measurement gratings are used on automated equipment, interference problems are emerging. Measurement of light curtain interference is mainly divided into external interference sources or light curtain mutual interference. External interference sources are mainly environmental factors such as solar light, fluorescent lights, etc., or interference with equipment inverters, electromagnetics, etc. Mutual interference of light curtains refers to mutual interference caused by multiple sets of measurement light curtains when used simultaneously.

Qily photoelectric measurement light curtain products from the hardware and software to solve the problem of light curtain interference, light curtain transmission and reception are using well-known brand components. Infrared modulation source, divergence angle small incident angle ≥ 5 °. The software uses synchronous modulation and the like. It has ensured that the interference problems of our products in use have caused problems for customers.
