Product Description
The product characteristic
l It needn't power supply when it works.
l Double poles excitation working mode. When the poles change for a circle, the sensor outputs a pair of plus-minus electrical pulse signals
l Only when the applied magnetic field's polarity changes, and the magnetic strength reaches the excitation threshold value, the sensor will output a pulse signal, so it won't cause trembling, it works stable and reliable.
l The signal amplitude has no concern with the changing speed of the field, and it can work under nearly zero speed.
l The signal processing is simple, and it can directly connect with transistor, comparator, and analog-digital converter
l Output signal can realize remote transmission by signal wire, and it's suitable for LAN management.
l No mechanical contacts, no electric spark, it's intrinsically safe component
Wide operating temperature, Strong adaptive capacity to environment
The sensor 's dimension and the sensitive silk locationl Example: The application of the water inlet of the water heater(see the following left figure) l Note: The sensor has some requirements for magnetic strength, too high or too low of the magnetic field will affect its operation ( see "the excitation magnetic strength" in the "Performance indicators".please find the operating mode in the following right figure (If using some other shapes of the magnet, the installation distance should be adjusted.).
