16 versions
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.
Features
- 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
