Through-beam sensors
Photoelectric sensors

163 versions
Through-beam sensors from Balluff serve to detect objects reliably, regardless of surface, color, material - even with a heavy gloss finish. They consist of separate transmitter and receiver units that are attuned to each other. When an object interrupts the light beam, this causes a change in the output signal in the receiver. Absolute reliability.
Features
- Ideal for positioning tasks thanks to excellent reproducibility
- Extremely resistant to contamination and has a large functional reserve
- Ideally suited for large operating ranges
- Transmitter and receiver in separate housings
