O. Another Way to Mount an Optical Encoder Instead of using an end bell, a lot of our motor manufacturer customers recess the QD145 optical encoder into an extended motor housing and then seal the motor with an endplate. This has the advantage of being a lower cost item to...

Which Encoder Wires Should I Use to Begin Understanding Incremental Encoder Signals? Channels A & B (Incremental Channels) Use only A (or only B) for an RPM or counting applications where the rotation is either unidirectional, or where you don’t need to know direction. Use A and B together to...

. I have interfaced a 200 line count QR145 optical encoder to a DL06 PLC. The PLC’s inputs are set up in high speed mode to receive the incremental quadrature pulses coming from the optical encoder. . CT174, the designated high speed up/down counter is used to interface to the...

An optical quadrature encoder is an incremental encoder with outputs consisting of two incremental channels that are out of phase by 90 electrical degrees. In each part of the encoder cycle, the two signals are in unique positions relative to each other. By comparing the difference between the high and...
