Encoder - Incremental
An encoder, or angle encoder, is a device that converts rotational movement into a digital output signal that can be processed via downstream evaluation electronics. All of our encoders operate on the principle of optical scanning. Inside the device is an impulse disc that, depending on the encoder, features either a unique (absolute) or repeating (incremental) scale, which is scanned by an optical system. Rotation of the encoder shaft causes the impulse disc to rotate, resulting in a corresponding scanning signal from the optical system. This signal is then converted by integrated electronics into encoder-specific output signals (e.g., multiturn, RS422, etc.). Shaft couplings, resilient bases (for mounting brackets or flanges) are used for proper installation in a wide range of applications. In addition, the encoder shaft can be equipped with measuring wheels or pinions in various versions and sizes. Typical application examples include angular measurement on bending machines, length measurement on strip lines, or speed measurement on winding systems.
