Optical Rotary Encoder offers differential style outputs.
At less than 1 in. high, model SC12 provides feedback solution for applications typically using modular encoders. Short-circuit-proof and reverse polarity-tolerant outputs consist of quadrature sine/cosine pair with index pulse and 3-phase commutation. Each unit is individually calibrated to compensate for normal construction variances, and output levels are stabilized due to source tracking of...
