BEI Sensors Anti-Dither Module

Controller seeing too many counts? Losing position in your control system? High vibration environment causing false counts? BEI's DIN rail mountable Anti- Dither module can help. By comparing the quadrature outputs on your encoder, the Anti-Dither Module can remove the unwanted part of the signal and give you a true picture of your system output. The Anti- Dither module accepts quadrature encoder A and B signals and, through internal discrimination circuitry, passes the signals through only when there has been true movement of the encoder. This acts like 1/4 cycle of hysteresis and avoids encoder signal transition dithering due to mechanical vibration. Idea for web processes, handling and inspection systems that use conveyors and simple speed control in applications that are subject to vibration.
