TMR4101
TMR4101 is High Precision Analog Magnetic Scale Sensor manufactured by MultiDimension.
Description
The TMR4101 magnetic scale sensor contains two push-pull half-bridges, each consisting of two high-sensitivity tunnel magnetoresistance (TMR) elements. The layout of the TMR elements matches the width of the magnetic poles. When the sensor moves along the length of the scale, the sensor outputs two quadrature sine wave signals, each corresponding to the width of a pair of magnetic poles. By decoding these two sine wave signals, the relative displacement between the chip and the scale can be accurately measured.
The TMR4101 magnetic scale sensor chip uses a small package DFN4L (1.32 mm × 0.66 mm × 0.3 mm), which reduces the requirements for chip installation, making the structural design of the system more flexible and convenient for assembly in narrow spaces.
Multi Dimension Technology can provide magnetic scale medium with customizable lengths as the accessory of TMR4101 to meet our customers’ needs.
