What is a 0-20mA encoder?
A 0-20mA encoder is an industrial device that converts mechanical motion—such as rotation or linear movement—into analog current signals ranging from 0 to 20 milliamps. This type of encoder is commonly used in automation systems for long-distance analog signal transmission and compatibility with controllers that accept 0-20mA inputs.
What does a 0-20mA encoder do?
The main function of a 0-20mA encoder is to provide accurate position, speed, and direction feedback through a 0-20mA current signal. This enables machinery to operate precisely, improves system efficiency, and ensures reliable process control in industrial environments.
Where are 0-20mA encoders commonly used?
0-20mA encoders are widely used in factory automation, process control systems, CNC machinery, and industrial equipment where analog feedback signals are preferred for direct integration with PLCs and other controllers.
Why choose a 0-20mA encoder?
Using a 0-20mA encoder provides noise-resistant, long-distance signal transmission, simple wiring, and compatibility with analog input systems. They are ideal for applications that require reliable, precise, and robust feedback in industrial environments.
