    Tips: What does a safety light curtain do?

    1. The safety grating is also a photoelectric safety protection device. The photoelectric safety device generates a protective light curtain by emitting infrared rays. When the light curtain is blocked, the device sends out a light-shielding signal to control the potentially dangerous mechanical equipment to stop working and avoid safety accidents.
    2. The installation of photoelectric safety protection devices can effectively avoid the occurrence of safety accidents, avoid the danger of operators and third parties, reduce the comprehensive cost of accidents, and benefit the company itself, operators, and society.
    3. Generally, the safety light grid is connected to the safety relay, and if an object is detected, it will automatically remove the power source that will cause harm. Cooperating with the safety relay can also temporarily suspend the function of the safety light barrier, allowing objects to pass through the safety light barrier without generating a protection signal, which is suitable for some semi-automatic procedures.

    Non-Contact Detection Advantage
    Infrared light curtain sensors operate without physical contact, which means they can detect objects or obstructions without any wear and tear. This non-contact detection is ideal for applications where maintaining the integrity of the object being sensed is critical.
