Mini Hollow Encoder

Principle of operation and wiring of encoders with Switches

switch encoder than ordinary rotary encoder more switch function, is a cost-effective encoder, many designers will be flexible to use it, today to introduce the working principle of switch encoder and switch encoder wiring.

The working principle of encoder with switch

When the switch (incremental) encoder shaft rotation, there will be a corresponding pulse signal output, the direction of rotation of the encoder can be judged with the number of pulses to determine the number of pulses, and need to rely on the back of the direction of judgement circuit as well as the counter to achieve. The starting point of the encoder counting can be set at will and unlimited accumulation and measurement of multiple revolutions can be realised at the same time. The Z-signal of one pulse per revolution is used as the reference mechanical zero position. Therefore, when the pulse signal is fixed, if you want to improve the accuracy of the encoder resolution, you can use the two signals A and B with a 90-degree phase difference to operate, that is, just multiply the frequency of the original number of pulses.

Wiring method of encoder with switch

General switch encoder has five pins terminal, generally the first three pins terminal were A, B, Z three-phase pulse output line, the other two were COM terminal line and power line. Its encoder wiring method is, first of all need to operate is the power supply - end (negative) and the encoder COM terminal connection, then the power supply + end (positive) and the encoder's power terminal line connection. Then next to the encoder's COM terminal and PLC input COM terminal connection, and finally the front three pins end A, B, Z three-phase pulse output line and PLC input connection can be.
