Precision encoders designed for seamless drop in integration

These linear encoders offer high-performance measurement technology that easily integrates into existing machine setups - often as a direct drop-in replacement for commonly used exposed linear encoder systems.

Both the MS 14 and MS 15 employ a singlefield reflective scanning principle, generating high quality sinusoidal signals with excellent immunity to contamination, aging effects and temperature fluctuations. They offer identical system measuring steps, ranging from 10 um down to 0.05 um, ensuring suitability for applications requiring fine positional accuracy.

Their regulated infrared LED and stable signal conditioning allow continuous, reliable measurement over long service lifetimes, even in industrial environments where dust, coolant, and vibration can affect lesser systems.

Installation made simple

A key advantage of both encoder families is ease of installation. The scanning heads include a three-colour LED to show real time signal quality, helping installers position the readhead quickly without separate testing tools.

Mechanical flexibility is another benefit: RSF offers steel tape scales with adhesive backing (MK), aluminium supported variants (MP), and glass or glass ceramic options for the MS 15 series.

Combined with standard TTL and 1 Vpp interfaces, both models integrate smoothly into existing control systems - ideal for retrofit scenarios where machine geometry and electronics must remain unchanged.

Clarifying the key difference: MS 14 versus MS 15

Although the MS 14 and MS 15 share nearly all functional features - including customisable bi-directional reference marks, contamination resistance, compact dimensions, and repeatable referencing - the primary distinction is that:

- The MS 15 includes two independent optical switching signals, enabling built in limit switches or special function triggers.

- The MS 14 does not include these dual switch/limit outputs, though otherwise offers equivalent scanning performance and capabilities.

This single difference makes the MS 15 the preferred option when integrated limit switch functionality is required directly from the encoder head.

A smart upgrade path

Thanks to their mechanical compatibility, robust design, and installer friendly features, both the MS 14 and MS 15 are excellent choices for upgrading older encoder systems without modifying machine layouts or electronics.

Whether for high precision machining, automation, or long travel applications, these encoders deliver dependable performance while simplifying the transition from legacy designs.
