Acu-Rite 

SENC 150

The SENC 150 from ACU-RITE is the ideal scale for all applications. 
The compact and robust design, and the numerous possibilities for mounting, make it ideal for retrofitting. The slight dimensions and high accuracies of this ball-bearing guided encoder, which uses the reflected light method, are ideal prerequisites for use in metrology applications.

Highlights:

    • Robust design
    • Resolutions from 0.5 µm to 5 µm
    • Output signals: TTL and sinusoidal
    • Measuring lengths from 75 mm to 3075 mm
    • Distance-coded reference marks
