NANJING AH ELECTRONIC WG Series zero power consumption sensor datasheet

WG Series Zero Power Consumption Sensor

Choosing Guide

Product Function

WG Series Zero power Consumption Senor is a new type magnetic sensor manufactured on

the basic of WIEGAND effect. It needn't external power supply when it works. It can directly

transform the magnetic signal into Electrical signal. The sensor is consists of an alloy wire which

has been specially processed and the

induction coil which is wound around

the Wiegand wire.

This kind of alloy wire owns dual

magnetic structure, its inner core is soft

magnetism, and its shell is hard

magnetic material. To utilize the

difference of the inner and outer

magnetic in the alloy wire, and is

activated by the alternating magnetic

field in proper strength, the

magnetization direction of the inner core

suddenly reversed, which is same with

the housing's magnetization direction or

the opposite directions, and the magnetic

field around the alloy wire suddenly changes, and generates a pair of positive and negative

electrical pulses in the induction coil. The amplitude of pulse is related to the strength of the

excitation magnetic field, and is not related to the changing speed of the magnetic field.

NANJING AH ELECTRONIC WG Series zero power consumption sensor datasheet Using method and matters need attention Magnetic circuit design The key whether the zero power consumption sensor can work normally is the magnetic circuit design. It should pay attention to the following points in the magnetic circuit design. 1. Alternately activated by N or S double poles, the distance between two poles should be near to or larger than the sensor's length. 2.

collect signal immediately, the software should arrange the single chip to do other work; c) whenever collecting a pair of high-low level signals, the counter will counts “1”. Packing, Transportation and Storage  Packing The original packing of the product is antistatic plastic bag, external packing is carton.  Transportation The product in the packing carton is admitted to transport by transportation facilities. It should avoid insolation, raining or mechanical extruder during transportation.
