Feature: 1. Far Infrared Design: Using high quality infrared lamp chips and light panel, far infrared design has strong anti light ability, and it can quickly and accurately respond to signals, greatly reducing the occurrence of accidents. 2. Multiple Protection: High protection level, the safety light curtains has short circuit, over current and reverse connection protection. The groove design of the back slide block has excellent seismic performance. 3. Aluminum Shell: The aluminum alloy shell structure is strong and has good sealing performance, dustproof, waterproof and oil proof, preventing foreign matter from intruding into the grating, and it is still sensitive in a relatively harsh working environment. 4. Intelligent Technology: Using intelligent technology and protection circuit safety self inspection design, if a failure occurs during work, the safety grating will be locked to a safe state to avoid accidents. 5. Other Functions: Multi function support, the light screen sensor supports power on delay, blind zone filtering, anti electromagnetic interference, etc., the protection height is up to 30‑2520mm / 1.1‑99.2in, and the detection distance is up to 3 m / 118ft.
