IC-ML Datasheet, PDF (1/17 Pages) IC-Haus GmbH – HALL Position Sensor / Encoder

iC-ML
HALL Position Sensor / Encoder
FEATURES
o Linear Hall sensor array for magnetic pole pitch of 2.56 mm
o Non-sensitive to magnetic stray fields due to differential
measurement technique
o Interpolator with 8-bit linear resolution of 20 µm
o Linear speed up to 5 m/s
o Buffered I/O stages for signal outputs
o Configuration inputs for operating mode selection
o Analog operation modes:
- sine/cosine signals controlled to 2 Vpp
- triange or sawtooth signal with selectable amplitude
o Digital operation modes:
- A/B quadrature signals with Z index pulse
- Counter pulses for external binary counters
o Cascading of multiple iC-ML possible for chain operation
(Evaluation of independent scales x, y, z)
o Error signal output for detection of low magnetic field strength
o Additional operating modes with reduced power consumption
o Standby modus when not enabled
o Extended temperature range of -40...+125 °C
Rev A3, Page 1/17
