Takex's PB Series Sensors feature double modulation frequency and phased-locked loop system which result in high-power beams that have 10x the maximum arrival distance and 100x maximum sensetivity. Simultaneous breaking of 4 beams is required to initiate an alarm, thus eliminating the most common causes of false alarms - small animals, falling leaves.Features
