Explosion-proof single-beam photoelectric sensors
Families LBD, LBN, LBG, ILD, ILN, ILO, ILG, AX-S, AX-ESingle-beam photoelectric sensors consist of separate housings where the transmitter and receiver are spatially separated. The transmitter directs its light directly at the receiver. When an object interrupts the light beam, the voltage at the receiver drops, triggering the switching function.
This principle enables the detection of opaque and reflective objects and allows for long detection ranges. Single-beam photoelectric sensors are robust and resistant to interference, making them particularly suitable for use in demanding conditions.
