NK External Interpolator

External interpolator

NK

The Interpolation and Digitizing electronics interpolates up to 10-fold and converts the sinusoidal scaning signals from photoelectric encoders to square-wave pulses with TTL levels. Possible interpolation factor: 1, 2, 3, 4, 5, 8, 10. Under the cover, the unit has a commutation switch that allows the Customer to change the interpolation factor.
