The Magnescale SR128 is a high-accuracy magnetic linear scale designed for precision digital readout (DRO) and position measurement applications. Originally supplied as part of the GB-A system, the SR128 remains available as a standalone scale and continues to be used on machine tools, measuring equipment and industrial automation systems worldwide.

Built around Magnescale’s proven magnetic sensing technology, the SR128 delivers reliable position feedback in environments where oil, dirt, vibration and shock can affect conventional measurement systems. Its compact profile, robust construction and high accuracy make it an ideal choice for both new installations and replacement applications.

Compact, Space-Saving Design suitable for retrofit and OEM applications.
Available Measuring Lengths from 50 mm to 2200 mm.
Maximum Response Speed of 60 m/min.
Simple Mechanical Construction designed for long service life.

Sucessor

Sucessor: SR138 (GB-ER)

CH01 cable is discontinued, SR128 scale is still available. Connector to the counter and output signal changed with the successor.

The SR127, SR128 and GB-A series of linear scales are semi-modular types that incorporate the detector inside the scale, and the relative positions of their scale and head are adjusted and secured using a slider holder.

The GB-A series includes an electrically adjusted connection cable (CH01 series), allowing it to be used as is with Magnescale display units (LG10, LH51/52, LH61/62, LY51/52 series act.) * Some models now discontinued
