Introduction to Encoders and Digital Switches
Encoders, also known as rotary encoders or digital switches, are electronic components that convert mechanical movement into digital electrical signals. These devices enable precise interaction with electronic systems, facilitating control, measurement, and automation.
At Electrónica Embajadores, we offer a comprehensive range of high-quality encoders and digital switches suited for industrial, automation, instrumentation, professional audio, and more.
What is an Encoder?
An encoder is an electromechanical device that translates angular position or rotational movement into a digital signal. This is achieved through an internal system of contacts, optical or magnetic sensors that generate electrical pulses proportional to the movement.
Encoders are used to control motor positioning, adjust parameters in electronic equipment, and provide precise interfaces between users and machines.
Types of Encoders Available
Electrónica Embajadores offers different types of encoders, each designed to meet specific needs:
Incremental Encoders
These generate electrical pulses proportional to movement. Ideal for measuring speed, distance, and relative position. Their signals require external processing to interpret the movement.
Absolute Encoders
Provide a digital signal indicating the exact angular position at any time, even after power loss. Used in systems requiring precise position without initial calibration.
Optical Encoders
Use optical sensors to detect position via a slotted or marked disc. Highly precise, widely used in high-resolution applications.
Magnetic Encoders
Detect position through magnetic sensors, making them highly resistant to dust, dirt, and vibration. Suitable for demanding industrial environments.
Mechanical Encoders (Digital Switches)
These are digital switches generating electrical signals via mechanical contact, used for option selection, settings, and basic controls.
