LM13 rotary incremental magnetic encoder system

More Views

The LM13 ring encoder features a compact sealed readhead and a magnetised ring. The actuator is a periodically magnetised ring with a pole length of 2 mm. Radial or axial reading of the ring is possible. The readhead can ride at up to 0.4 mm from the ring's surface.

 

Simple to install, the LM13 features an integral set-up LED on the readhead and wide installation tolerances. The encoder is available with analogue or digital outputs and offers a range of customer selectable interpolation factors. The LM13 is capable of speeds up to 20,000 revolutions per minute.

 

Engineered for extreme service, the solid-state LM13 ring 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 ring 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 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.
