Overview
What it is
LBGate R18 is a reflection (retro-reflective) light barrier: transmitter and receiver are in one housing and the red light beam returns from a polarised reflector on the opposite side.
What it is used for
Closing protection on sliding gates, vertical doors and sliding doors, and presence detection at escalators and revolving doors, where cabling the far side is difficult.
Key features
- Range 9 m with double signal reserve.
- Polarisation filter, so shiny and reflective objects are still detected.
- Supplied with LBGate REF84 reflector (84 mm) and fixing bracket.
- Wide-range supply 12 to 240 V DC or 24 to 240 V AC, below 2 VA.
- Changeover relay up to 240 V AC, below 3 A; response time 25 ms.
- IP67, 62 x 35 x 18 mm polycarbonate housing, sealed-in 2 m cable.
Buying considerations
For spans over 9 m choose the through-beam TB18 (30 m). For a terminal compartment instead of a fixed cable, see LBGate R25.
Installation considerations
Only one device needs electrical connection. Operating temperature is -25 to +55 °C. A smaller REF46 reflector is available.
Compatibility
Connects to the photocell or safety input of gate and door controllers through its changeover contact.
