RSF Elektronik: Exposed Linear Encoder (MS 15 Series)

RSF Elek tronik: MS 15 Series (Exposed Linear Encoder with Singlefield Scanning) Features: Small dimensions System resolution: 2 µm - 0.1 µm Indication of signal quality directly at the scanning head via 3-coloured LED Easy mounting without additional test box Easy mounting as a result of large mounting tolerances High insensitivity to contamination by use of an extensive singlefield scanning principle Output signals: TTL, sinus 1 Vpp High traversing speed Reference mark (accurate and repeatable from both traversing directions) Position selectable by customer Integrated subdividing electronics in the encoder head: for up to times 100 interpolation (before quadrature) Max. measuring length: 20 000 mm Two independent switch signals (optical) for individual special functions 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 . The regulated light of an infrared LED is collimated by a condenser lens and passes through the grid of the reticle. After being reflected from the scale, the infrared LED generates a periodic intensity distribution on the structured sensor. The sensor generates high quality sinusoidal signals which are highly insensitive to possible contaminations. The regulation of the LED ensures a constant light output, guaranteeing stability in the case of temperature fluctuations as well as with long-run operation.
