RSF Elektronik: MS 14 Series

(Open Linear Encoders with non-contact singlefield scanning)

The trend today in motion control applications is for exposed Linear Encoder systems.

This is driven by steadily increasing demands for

Only exposed, non-contact encoders fulfill all these requirements.

It is important for high resolution applications to minimize interpolation errors. Historically, the small grating periods used had the disadvantages of smaller mounting gaps and very tight overall mounting tolerances. The MS 14 encoders´ 40 μm grating period minimizes interpolation errors but can be mounted with a large mounting gap and liberal mounting tolerances.

A drawback of many exposed Linear Encoders is their sensitivity to dirt and contamination on the scale. The MS 14 encoders´ unique optical design minimizes the effect of dirt and contamination normally associated with the exposed Linear Encoders.

The MS 14 utilizes a unique scanning principle which allows high traversing speeds (up to 10 m/s), large mounting tolerances, and contamination on the scale.

Reference marks, accurate and repeatable from both traversing directions, are standard.

A wide range of interpolation electronics, integrated into the encoder head, enable resolutions from 2 μm to 100 nm.

Square-wave signals via Line Driver RS 422, are provided at the output of the encoder head. Units with sinusoidal output, 1 Vpp, are also available. Due to recent advancements in technology, all of these benefits are now available in a small package design.
