Descriptions of Wenglor PNBC002 Laser Distance Sensor High Precision
Sensors from the PNBC range work with a high-resolution CMOS line array and determine the distance to the object by means of angular measurement. Top-quality optics permit measured values with 16-bit resolution. Thanks to proven algorithms, stable measured values are obtained even for complex surfaces, for example, sheet metal with a speckle effect.
They demonstrate outstanding accuracy with a maximum linearity deviation of just 0.05% and require only a short warm-up phase thanks to minimized temperature drift. Values are read out simultaneously via the analog output and the interface. Up to 4 switching outputs can be taught externally. An incremental encoder input rounds the product out.

Features at a Glance
- Highly precise measurement with a maximum linearity deviation of 0.05%
- Constant, surface-independent measured values
- Thermally stable measured values without any warm-up phase
