BEI Newall Incremental Linear Encoders provide sine-cosine or quadrature square wave feedback signals that allow for direct integration to servo or non-servo driven applications.

BEI Newall encoders are based upon Spherosyn™ technology and operate on the principle of electromagnetic induction. Inducing a 10kHz sinusoidal current through a single drive coil within the reader head generates an electromagnetic field. This field interacts with the nickel chrome elements contained in the scale.

A set of four pickup coils detect variations in the induced field that are then combined and processed by the electronic circuitry to generate a signal that varies as the head moves along the scale. Depending on the position of the reader head as it passes over each element, the phase shift of this pickup signal relative to the drive signal will vary between 0 and 360 degrees. A high-speed digital-signal processor (DSP) converts the analogue signal to an industry standard differential signals. The DSP also generates the reference marker pulse.

Alternatively, also available as an incremental encoder, the MAG-TS encoder system features a flexible, magnetically encoded tape scale, and is ideal for both rotary and linear automation applications.

Signal Model Description
TTL Differential AB Quadrature - Periodic

    Quick and Easy Installation


     

    The design of these linear encoders allows installation in almost any position, unlike glass-scale linear encoders, which usually need to be installed with the lip seal facing downwards to prevent contamination. Self-aligning fixing brackets allow virtually effortless scale mounting, needing only a single hole for each set of brackets or direct installation into machine frames in OEM applications.
