Photoelectric sensors

Available in:

1 Series

Contrast sensors are high-resolution diffuse sensors that distinguish objects based on their gray values. The robust BKT contrast sensors from Balluff detect even small differences in contrast, have a high switching frequency up to 30 kHz, and are especially fast. They enable high positioning accuracy and are suitable for a wide range of applications, such as in the printing and packaging industries.

The special features of our contrast sensors

  • Pinpoint accurate switching for fast processes with a high switching frequency of up to 30 kHz
  • Different light types (laser, red/green/blue or white light)
  • Large ranges with laser
  • Clearly visible light points for easy alignment
  • Pulse extensions
  • Outside teach-in possible
  • Also available with analog output signal
  • Easily adjustable via the display (also available without)
  • Different model series for different applications
