Application Note

Magnetic Encoder System (MES)
for Linear Motors AL2xxx

Features

MES consists of a read head with integrated analog hall effects. These hall effects will
analyze the magnetic field of magnet plate and supply an analog output signal.

Signal Period: 24 mm pole pitch

Output Signal: 1 Vpp, Sine-Cosine

Termination: R = 120 Ohm

Accuracy: < 100 µm

Pre-conditions are precise assembly of magnet plates within

± 20 µm and offset-, phase- and amplitude compensation
within the drive.

Repeatability: < 50 µm

Resolution: 5 - 10 µm

Power supply: 5 VDC

Connection cable: 8-wire, twisted pair, PUR, UL

diameter 3.2 mm, length 3 m
