Renishaw: Linear Incremental Magnetic Encoder System LM13

The LM13 is a contactless high-speed linear magnetic system designed for use in harsh environments.

The system consists of a compact readhead and a self-adhesive magnetic scale.

Simple to install, the LM13 features an integral set-up LED on the readhead, wide installation tolerances and an applicator tool for the adhesive-backed magnetic scale. A bidirectional reference is provided that can be either actuated by a preset mark integrated within the scale or by adding a reference sticker on top of the scale with the help of a self-aligning installation tool.

The encoder comes in digital output variants and offers a range of customer selectable resolutions 1 µm, 2 µm, 4 µm, 5 µm, 10 µm, 20 µm, 25 µm, 50 µm, 125 µm and 250 µm. The LM13 is capable of velocities up to 25 m/s; even at 1 µm it is capable of 4 m/s.

Due to its compact size and internal build, the LM13 is also suitable for partial arc applications. The self-adhesive magnetic scale can be installed on surfaces with a minimum radius of 60 mm.

Engineered for extreme service, the solid-state LM13 linear encoder operates from -10 °C to +80 °C, has water-proof sealing to IP68 and is highly resistant to shock, vibrations and pressure. The robust magnetic scale is also resistant to a range of chemicals commonly found in industry. The non-contact, frictionless design eliminates wear while reducing hysteresis giving precision at high speeds and accelerations.

The LM13 linear encoder system brings reliable solutions to tough, hard-working applications including woodworking, stone-cutting, sawing, metalworking, textiles, packaging, plastics processing, automation and assembly systems, laser/flame/water-jet cutting, electronic assembly equipment etc.

For applications which demand that the MS scale can be removed easily please consider TRS track system.
