ZMZ20数据手册传感器变送器的磁性传感器-线性罗盘（IC）规格书PDF

描述 Description

he ZMZ20 is an extremely sensitive magnetic field sensor in a 4 pin
E-Line package employing the magneto-resistive effects of thin film
Permalloy. It allows the measurement of magnetic fields or the detection
of metallic parts. The sensor consists of a chip covered with Permalloy
stripes which form a Wheatstone bridge, whose output voltage is
proportional to the magnetic field component Hy. A perpendicular field
Hx is necessary to suppress the hysteresis and this can be provided by
using a small permanent magnet.

特性 Features

Output voltage proportional to magnetic field HyAdjustment of sensitivity and suppression of hysteresis by the auxiliary magnetic field HxMagnetic fields vertical to the chip level are not effective

应用 Application

Linear position sensors for process control, door interlocks, proximity detectors, machine tool sensingScalar measurement for compassingAutomotive - door switches, engine position and speed sensingMetering of fluids by sensing rotation of impellerTraffic counting and vehicle-type sensingMeasurement of current in a conductor without connection
