LM15 linear magnetic encoder system
The LM15 linear magnetic encoder system has been designed for use in harsh and unfriendly environments.
Overview
Introduction
The LM15 features a compact sealed readhead that rides at up to 4 mm from the self-adhesive magnetic strip scale, which brings 100 m travel.
Simple to install, the LM15 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 actuated by a preset mark integrated within the scale or periodically every 5 mm.
The encoders come in digital output variants and offer a range of customer selectable resolutions 5 µm, 10 µm, 25 µm, 50 µm, 125 µm and 625 µm. The LM15 is capable of velocities up to 50 m/s; even at 25 µm resolution it is capable of more than 42 m/s.
Engineered for extreme service, the solid-state LM15 linear encoders operate from -20 °C to +85 °C, have water-proof sealing to IP68 and are 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 for high precision at high speeds and acceleration.
The LM15 encoders bring 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.

Accessories
Further information on the accessories can be found in the datasheet under the Documentation tab.
Applicator tool for magnetic scale
This applicator tool can be mounted in place of any RLS LM15 readhead and uses motion of the axis to apply the MS15 tape scale parallel to the guideway. The installation guide can be found in the Documentation tab.
Part number: LM10ASC00
End clamps for magnetic scale
The end clamps have been designed to anchor the ends of the MS magnetic scale. The installation guide can be found in the Documentation tab.
Part number: LM10ECL00
TRS track system
The TRS track system has been designed for applications which demand that the scale be removed easily. The magnetic scale is simply inserted in the aluminium track section. More information can be found under Related products.
Interfaces
P201 USB encoder interface
The P201 is a single channel USB encoder interface suitable for use with a wide variety of 5 V rotary and linear encoders. It allows encoders to be easily interfaced and powered from a PC using only a USB cable. For more information on the product click here.
