LM15 rotary incremental magnetic encoder system

More Views

The LM15 ring encoder features a compact sealed readhead and a magnetised ring. The actuator is a periodically magnetised ring with a pole length of 5 mm. Radial 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 LM15 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.


Engineered for extreme service, the solid-state LM15 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 giving precision at high speeds and accelerations..

The LM15 encoder system brings 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.
