DATA SHEET HLD01_03 Issue 3, 20th September 2021 HiLin™ High-accuracy Linear Magnetic Encoder System HIGH ACCURACY The HiLin series of high accuracy magnetic encoders is a family of linear incremental systems suitable for a variety of demanding applications. The incremental encoder system consists of a compact sealed readhead and a separate magnetic scale. The readheads are available in high resolution and upon request offer customer-selectable interpolation factors that allow much more freedom in designing advanced systems. At the same time, low hysteresis and low interpolation error can be easily achieved, while maintaining a ride height tolerance within 0.2 ±0.1 mm. ROBUST DESIGN HIGH SPEED Features and benefits ⯈ Customer selectable resolutions down to 0.1 µm ⯈ High speed: 25 m/s with 1 µm resolution ⯈ Unique, periodic or distance-coded reference mark ⯈ Low hysteresis: ≤1 µm ⯈ Industry-standard digital incremental RS422 output ⯈ Wide operating temperature range from –40 °C to +75 °C LINEAR MOTOR PRINTING TECHNOLOGY

General information The encoders provide an industry standard digital RS422 output. The readheads are fully sealed and feature high IP67 environmental protection, ensuring reliable operation in environments contaminated with particles, vapours and liquids. If damaged, a readhead can be easily replaced due to a detachable cable, which reduces costs. Depending on the requirements of the application, different magnetic scale options can be selected. The most cost effective, lightweight and compact option is a self-adhesive scale with an accuracy of ±10 µm, which allows longer measuring lengths....

Storage and handling Storage temperature Operating temperature High resistance to humidity Readhead is ESD sensitive - handle with care. Do not touch electronic circuit, connector pins, wires or sensor area without proper ESD protection or outside of ESD controlled environment. HANDLE WITH CARE HiLin encoder system is a high performance metrology product and should be handled with the same care as any other precision instrument. The use of industrial tools during installation or exposure to strong magnets such as a magnetic base is not recommended as it carries the risk of damaging parts of the...

Installation instructions Installation of MS19/20 magnetic scale with adhesive tape Installation surface preparation MS19 and MS20 magnetic scales are equipped with VHB backside adhesive tape. Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol and water before applying the magnetic scale. Exceptions to the general procedure that may require additional surface preparation include: ⦁ Heavy oil/grease: To remove heavy oil or grease from a surface, a degreaser or solvent-based cleaning agent may be required, followed by cleaning with IPA/water. ⦁ Abrasion: Sanding...

Load the scale into the applicator tool. Separate the backing paper from the first 40 mm of scale and feed the scale into the applicator tool. Apply the scale. Push the scale carefully through to the end of scale mark, ensuring that it does not stick to the mounting surface until it is in position. Attach the end of the scale to the mounting surface with light finger pressure. Ensure complete adhesion. Apply firm finger pressure along the full length of the scale from the centre outwards to each end. Traverse the axis through its full travel at a slow, steady speed. While moving the axis apply...
