Electric photocell sensor encoder
The form of the encoder shaft: the shaft is extended and must be equipped with a coupler before it can be used; the hollow shaft, without a coupler, can be directly used on the other equipment.
Grating pollution This will reduce the signal output amplitude, so you must use absorbent cotton dipped in absolute alcohol to gently wipe off the oil
Absolute rotary encoder high-speed end installation: installed on the power motor shaft end (or gear connection), this method has the advantage of high resolution
The COM terminal of the encoder is connected with the PLC input COM terminal, and the A and B two-phase pulse output lines are directly connected with the PLC input terminal. When connecting, pay attention to the response time of the PLC input.
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.
The parameters that the encoder pays attention to: mechanical installation dimensions: including positioning stop, shaft diameter, installation hole position; cable outlet mode; installation space volume; whether the working environment protection level meets the requirements
One advantage of the multi-turn encoder is that due to the large measuring range, the actual use is often richer, so it is not necessary to find a change point during installation, and a certain intermediate position can be used as the starting point, which greatly simplifies the difficulty of installation and...
Incremental encoders have no memory. Power off and restart must return to the reference zero position to find the desired position, while absolute encoders have memory, and power off and restart do not need to return to the zero position to know the target position
There are usually three types of encoders on the market: Optical Encoder, Magnetic Encoder, and Capacitive Encoder
In an optical encoder, the black lines block the light; the transparent window allows the light to pass through the code disc (or reflect on the code disc) to reach the sensor. When the sensor receives light, it outputs a high level, and when the light is blocked, it outputs a low level
Inside the capacitive encoder, there is a transmitter that emits high-frequency signals, a rotor that modulates the signals, and a receiver that converts the signals and sends them to the motion controller.
Encoder optical sensor encoder
Optical encoders are the most commonly used and the most accurate, but they are also the most expensive
