LM15 rotary incremental magnetic encoder system

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.

 

Please be informed that incremental magnetic rings with reference mark currently have longer lead time and were temporarily removed from our online shop. We handle all requirements on a case by case basis so please send your RFQ to sales@rls.si.
