Optical Edge Detector Input

The Deva037 incorporates a dual input optical edge detector system. Encoder positions can be latched when the optical level present at the signal input crosses a pre-programmed threshold. Furthermore the reference input can be used improve the signal quality by receiving light from the illumination...
