Link

The MSS975R is a compact, high-accuracy linear scale rod designed for integration with Magnescale reader heads such as the HA721SP. Engineered for demanding environments like rolling mills, it forms a core part of the SR721SP open-core scale system, delivering reliable and repeatable measurements.

Key features

Compact Design: Ideal for space-constrained installations.
High Accuracy: Accumulative error of ±3μm over 200mm effective length.
Durable Construction: Built to withstand harsh industrial conditions.
System Integration: Pairs seamlessly with HA721SP reader head and MD20B interpolator.
Flexible Measurement Lengths: Available in multiple effective lengths to suit various applications.
