Product Description

Automatic Car Door Opening System

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.
