What is a 4-20mA encoder?
A 4-20mA encoder is an industrial device that converts mechanical motion—such as rotation or linear movement—into analog current signals ranging from 4 to 20 milliamps. This type of encoder is widely used in industrial automation for long-distance signal transmission and integration with controllers that accept analog input.
What does a 4-20mA encoder do?
Its main function is to provide accurate position, speed, and direction feedback in the form of a 4-20mA current loop. This allows machinery to operate precisely, improves efficiency, and ensures reliable control in various industrial processes.
Where are 4-20mA encoders commonly used?
4-20mA encoders are commonly used in process control systems, factory automation, CNC machinery, and industrial equipment where analog feedback signals are preferred or required for integration with PLCs and other controllers.
Why choose a 4-20mA encoder?
Choosing a 4-20mA encoder ensures long-distance, noise-resistant signal transmission, simple wiring, and compatibility with analog input controllers. They are ideal for industrial applications that require reliable, precise, and robust feedback in harsh or electrically noisy environments.
