The PB3-4L15 is a compliant monitored device that replaces a photo eye for most commercial and industrial door applications. There's no need for an external control box. This system uses a series of thru-beam photo eyes attached near the door track or door guides.
The light curtain provides a dense barrier of light that, when interrupted by the presence of an obstacle, signals the door's motor to stop and reverse operations. This Edge light curtain with waterproof housing can span up to 20m wide range and 30cm high.
Infrared fence integrated high-efficiency alarm system can be triggered at the same time independent alarm, no need to go through alarm host.
High quality imported industrial-grade infrared emitter. The infrared beam is not scattered, providing better stability and longer service life.
Fully sealed waterproof and dustproof design ensures reliable operation regardless of wind and rain conditions.
Features a 2-second delay for single beam blocking to avoid triggers from small animals or leaves. Dual or adjacent beam blocking triggers immediately.
Equipped with 180 Omni-directional rotation focus, making installation and alignment easy and flexible in any direction.
If the infrared grating is illegally disassembled or the cable is cut, an alarm will be triggered immediately for enhanced security.
