Encoders are in stock with same-day shipping at Mouser from industry leading manufacturers. Mouser is an authorized distributor for many encoder manufacturers including Bourns, Broadcom, Electroswitch, Grayhill, Same Sky, Sensata, TE Connectivity & more.

Encoders are sensing devices designed to convert mechanical motion, position, speed, or direction into electrical signals that can be interpreted by control and monitoring systems. They provide precise feedback that enables accurate positioning, automation, and motion control across a wide range of electronic and electromechanical applications. These devices serve as critical components in closed-loop control systems, helping improve accuracy, efficiency, and operational reliability.

Types: The most common encoder types include rotary encoders, linear encoders, incremental encoders, absolute encoders, optical encoders, magnetic encoders, shaft encoders, and hollow-shaft encoders, each optimized for specific motion sensing, positioning, and control requirements.

Applications: Encoders are widely used in industrial automation systems, robotics, motor control equipment, CNC machinery, conveyor systems, medical devices, transportation systems, and test and measurement equipment to provide position, speed, and motion feedback.

Selection requirements: To choose encoders, evaluate resolution, accuracy, sensing technology, output type, rotational or linear travel requirements, environmental protection rating, operating temperature range, mounting configuration, and suitability for the intended operating conditions.
