Description
iC-SM2L is a linear position sensor which operates on the AMR effect (anisotropic magneto resistance) and has been designed to work with magnetic scales which have a N/S pole pitch of 2 mm. When the sensor is moved along a magnetic scale with a N/S pole pitch of 2 mm the two Wheatstone bridges generate differential sinusoidal output voltages (PSIN – NSIN) and (PCOS – NCOS) phase-shifted at 90
Features
Magneto resistive position sensor based on the AMR effect
Strong field sensor for 2?mm N/S pole pitch
One sine/cosine cycle per pole width (averaged using a pair of N/S poles)
High interpolation due to a sine signal with few harmonics
Low saturation field strength
High amplitude consistency with changes in distance
Resistant to strong magnetic fields
Not sensitive to external homogenous magnetic fields
Small SMT capable package
Applications
Linear position sensing
Length measuring systems
Off-axis hollow shaft rotary encoders
