RSF Elektronik: MS 15 Series

(Exposed Linear Encoder with Singlefield Scanning)

Features:

Overview:

For special requirements like closed loop, speed control, highest accuracy and others it is important to minimize the interpolation errors.

Historically, the small grating periods used had the disadvantages of smaller mounting gaps and very tight overall mounting tolerances. The MS 15 series encoders´ 40 μm grating period minimizes interpolation errors but can be mounted with a large gap and liberal mounting tolerances.

A drawback of many exposed Linear Encoders is their sensitivity to dirt and contamination on the scale.

The MS 15 series encoders´ unique optical design minimizes the effect of dirt and contamination normally associated with the exposed Linear Encoders.

The MS 15 series 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.

The position of the reference mark can be selected by the customer.

A wide range of interpolation electronics, integrated into the encoder head, enables resolutions up to 100 nm.

Square-wave signals, single ended, or via Line Driver RS 422, are provided at the output of the encoder head.

Units with sinusoidal output, 1Vpp, are also available.

Two end of travel optical switch signals are available directly out of the reader head. The end of travel signal locations can be easily set by the user.

Due to recent advancements in technology, all of these benefits are now available in a small package design.

Scanning Principle:

The model MS 15 series incremental Linear Encoder system works with the imaging, photoelectric measuring principle and a singlefield reflective scanning method.
