okplazas30S series-incremental encoder

The incremental encoder converts the displacement into a periodic electric signal, and then converts this electric signal into a counting pulse, and the number of pulses is used to indicate the magnitude of the displacement.

Encoder is a device that converts angular displacement or linear displacement into electrical signals. The former is called a code wheel, and the latter is called a yardstick. Encoders can be divided into contact type and non-contact type according to the read mode. The contact type uses an electric brush to output. A brush touches the conductive area or the insulating area to indicate whether the status of the code is "1" or "0"; the non-contact type receiving sensitive element is a photosensitive element or a magnetic sensitive element. The light-transmitting area and the opaque area indicate whether the status of the code is "1" or "0".

When the rotary shaft of the incremental encoder rotates, there is a corresponding pulse output. The discrimination of the rotation direction and the increase or decrease of the number of pulses are realized by the direction discriminating circuit and counter at the rear. The starting point of counting can be set arbitrarily, which can realize unlimited accumulation and measurement of multiple circles. It is also possible to use the Z signal for each pulse transmitted as a reference mechanical zero position. One rotation of the encoder shaft will output a fixed pulse, and the number of pulses is determined by the number of encoder grating lines. When you need to improve the resolution, you can use the A and B signals with a 90-degree phase difference to multiply the original pulse number, or replace the high-resolution encoder.
