Overview
What it is
LBGate TB18 is a through-beam light barrier, often called a photocell pair: a red-light transmitter and a separate receiver face each other across the opening. When something interrupts the beam, the receiver relay switches.
What it is used for
Preventing sliding gates, vertical doors and sliding doors from closing on people or vehicles, protecting revolving door panels and triggering escalators when people approach.
Key features
- Operating range up to 30 m with double signal reserve.
- Wide-range supply: 12 to 240 V DC or 24 to 240 V AC.
- Changeover relay contact, up to 250 V AC and below 3 A.
- Response time 25 ms.
- Compact 62 x 35 x 18 mm polycarbonate housings with sealed-in 2 m cables, IP67.
- Visible LED on the receiver makes alignment quick.
Buying considerations
A through-beam pair needs power at both sides of the opening. If only one side can be wired, the reflection models LBGate R18 or R25 need only one powered device and a reflector.
Installation considerations
Fixing brackets are included. The function can be tested without a switching unit by switching off the transmitter supply. Operating temperature is -25 to +55 °C.
Compatibility
The relay contact connects to the photocell or safety input of gate and door controllers. Bircher suggests ProLoop2 for gate activation and ClickLine edges for closing-edge protection alongside it.
