Photoelectric sensors

153 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
