Popular Beam Sensor Photocell Sensors : 12-24v BS-IR33 BS-IR33 Power supply:12V~24V; Range:≤10m; Infrared Frequency:1.92KHz; Input:RX15mA, TX30mA;      Features: Popular Beam Sensor Photocell Sensors : 12-24v BS-IR33   1.Single beam sensor/single beam detector is used for automatic slide door, coil door , garage door windows etc. 2.Consists of a transmitter and a receiver, and the integrated amplifier can produce infrared beam. Narrow infrared beam (I or II) can avoid interruption by external light. 3.Even installed at low height(20-40cm from the floor), the detecting distance can also be guaranteed(5-15meters). 4.The beam produced by MICROCELL provides a self-detecting function for the sliding doors. Once the self-detecting beam is interrupted, the door will stop closing and reverse rapidly to the utmost width. The door will open until the detecting beam is resumed. When the door completely closes, the detecting beam becomes invalid.   We are Available at:  Popular Beam Sensor Photocell Sensors : 12-24v BS-IR33 Vickey  Chan Mobile: +86  13870868175 Skype: vickeychan   whatsApp:     +86 13870868175
