Compact and robust housing Designs to proven industrial standard Cable entry for axial and radial use Versions with integrated fieldbus interfaceHollow shaft encoder for direct mounting on actuators Encoders use the wear-free photoelectric or magnetic detection. A pulse disc firmly attached to the shaft or a movable magnet carrier ensures this detection. A distinction is made between incremental and absolute encoders. Incremental encoders generate a precisely defined number of pulses per revolution.
Simply put, an encoder is a sensing device that provides feedback. Encoders convert motion to an electrical signal that can be read by some type of control device in a motion control system, such as a counter or PLC. The encoder sends a feedback signal that can be used to determine position, count, speed, or direction. An encoder is classified into four types: mechanical, optical, magnetic, and electromagnetic induction types.
Summary. An encoder is a sensor that detects rotation angle or linear displacement. Encoders are used in devices that need to operate in high speed and with high accuracy. There are two main types of each encoder, ‘absolute encoders’ and ‘incremental encoders’. An Encoder is a combinational circuit that performs the reverse operation of Decoder. It has maximum of 2n input lines and ‘n’ output lines. It will produce a binary code equivalent to the input, which is active High. Therefore, the encoder encodes 2n input lines with ‘n’ bits.
