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
