LM10 linear magnetic encoder

LM10 linear magnetic encoder

More Views

The LM10 is a contactless high-speed linear magnetic encoder designed for use in harsh environments.

The LM10 features a compact sealed readhead that rides at up to 1.0 mm from the self-adhesive magnetic strip scale, which brings up to 100 m travel.

Simple to install, the LM10 features an integral set-up LED, wide installation tolerances and an applicator tool for the adhesive-backed magnetic scale. A bidirectional reference is provided that can be actuated either 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 encoders come in digital or analogue output variants and offer a range of customer selectable resolutions from 0.244 µm to 250 µm. The LM10 is capable of velocities up to 80 m/s; even at 1 µm resolution it is capable of more than 7 m/s.

Engineered for extreme service, the solid-state LM10 linear encoders operate from -10 °C to +80 °C, have water-proof sealing to IP68 and are highly resistant to shock, vibration 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.

The LM10 encoders bring reliable solutions to tough, hard-working applications including woodworking, stone-cutting, sawing, metalworking, textiles, printing, 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.
