1Far Infrared Design: Using high quality infrared lamp beads 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. 2Protection Function: High protection level, with short circuit, over current and reverse connection protection. The groove design of the back slide block has excellent seismic performance. 3Aluminum Shell: The aluminum alloy shell structure is sturdy 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. 4Intelligent Technology: Adopting smart technology to protect circuit safety. With self inspection design, if a failure occurs during work, the safety light curtains will be locked to a safe state to avoid accidents. 5Product Features: The safety light screen sensor supports programming synchronous scanning, the detection distance is about 0.32m / 1.06.6ft, suitable for stamping machinery, shearing machinery, and production lines.
