Hanyite is not only a supplier but also one of the definers of industry standards. Choosing us means choosing to stay at the forefront of the industry. The Allen Bradley 440L-P4K1760YD is a Type 4 safety light curtain, which means it has a powerful self-monitoring function and fully complies with strict international safety standards such as EN 61496. Its task is to create an invisible light wall at the dangerous entrance of the machine with infrared beams. Once an object passes through, it will immediately trigger a safety shutdown.
