Through-Beam Sensors

The transmitter and receiver in through-beam sensors are integrated in separate housings. The output switches if the light beam is interrupted. The function of the transmitter and receiver can be tested with a test input.

Through-beam sensors are available with laser light, red light or infrared light. The fine laser beam creates a small spot of light, which can be used to reliably detect even the smallest parts. Their good visibility facilitates easy adjustment and commissioning, even at great distances. In the case of some laser through-beam sensors, the focus is adjustable.
Aligning through-beam sensors with red light is very easy thanks to the visible light spot.

Application examples:

  • Detecting and counting extremely small parts
  • Edge detection
  • Pass monitoring
  • Drill breakage control
