Renishaw LM13 linear magnetic encoder

The Renishaw LM13 linear magnetic encoder is 14 mm tall and consists of a read head and separate self-adhesive scale. This form of magnetic sensing is suitable for applications that are too dusty, dirty, greasy or destructive for optical encoders.

The LM13 has selectable resolutions and speeds up to 4 m/s and is suitable for operating temperatures from 10 to 80°C. It provides waterproof sealing to IP68 and high resistance to shock, vibration and pressure. Frictionless operation eliminates wear while reducing system inertia and hysteresis for precision at high speeds and accelerations.

The encoder produces a digital, square-wave signal output to RS422, with nine customer-selectable resolutions between 1 and 250 µm and velocities up to 4 m/s at 1 µm resolution. It comes with a bidirectional reference that can be actuated by a preset mark integrated into the scale or by adding a reference sticker on top of the scale using the self-aligning installation tool.

Simple to install, it features an integral set-up LED on the read head, wide installation tolerances and an applicator tool for the adhesive-backed scale. The scale is available either cut to length or in lengths up to 100 m in easy-to-handle coils.
