Frequently Asked Questions about Encoders

What is an Incremental Encoder An incremental rotary encoder provides cyclical outputs (only) when the encoder is rotated. They can be either mechanical, optical or magnetic.

Absolute-Gray code encoder Gray code encoder, is well known as reflected binary code encoders, only a single bit change at each step, which can reduce encoder communication errors.

Which signal output to use while choosing a encoder

Wiring, testing and use specification of adjustable potentiometer Adjustable potentiometer wiring The adjustable potentiometer is composed of 3 terminal pins. Generally, the left and right pins are the main body of the potentiometer, that is, the two end points of the overall resistance, and the middle pin is the output terminal.

What is the cause of potentiometer noise The potentiometer is actually a variable resistor, because its function in the circuit is to obtain an output voltage that has a certain relationship with the input voltage (external voltage), so it is called a potentiometer.

Under what circumstances should I choose an absolute encoder We all know that there are absolute encoders and incremental encoders for rotary encoders. The two look the same, but the performance is quite different. Some designers should be guilty of choice phobia and choose incremental encoders.

Tips for purchasing rotary encoders Rotary encoders are sensors for speed, displacement, angle, and distance feedback to ensure high-precision and stable operation of machinery, thereby improving production efficiency and ensuring safe operation.

Steps to replace the potentiometer Under the condition of long-term operation and use, the potentiometer may malfunction and cannot be repaired, causing the whole machine to malfunction. At this time, we need to replace the obsolete potentiometer. The specific steps for replacing the potentiometer are as follows:

Specification for the use of automotive potentiometers Car potentiometers generally include car audio potentiometers, car air conditioner potentiometers, and car navigation potentiometers. Potentiometers can be used for tuning, temperature adjustment and function selection.
