Product Details

PBX, photocopiers, washing machines, refrigerators, cameras, disinfectant cabinet, door, window magnetic, electromagnetic relays, electronic weighing, level meter, gas meter, water meter and so on have been very good application.
Module Features:
1, normally open reed
2, the comparator output signals clean, good waveform, driving ability, than 15mA.
3, the working voltage of 3.3V-5V
4, the output form: digital switching output?0 and 1?
5, a fixed bolt hole for easy installation
6, small PCB board size: 3.2cm x 1.4cm
7, using a wide voltage comparator LM393
Reed features:
Reed is dry reed short, is a kind of passive electronic switch contact element has a simple structure, small size and easy to control, etc., the shell is generally a sealed glass tubes are installed there are two flexible iron reed panels, also called metal rhodium has a filling of inert gas. Normally, two glass tubes made of materials reeds are separated. When a magnetic substance near the glass tube, under the action of magnetic field lines, the two reed pipe is magnetized and attract each other contacts, the reed will pull together to make a circuit of the connected node communication. After the disappearance of the external magnetic force, two reeds separately because of their elasticity, the line also disconnected. Therefore, as a signal to control the use of magnetic field lines switching devices, the reed can be used as a sensor for counting, spacing, etc.? duction in the security system is mainly used for door sensor, window magnetic?And it was also widely used in a variety of communications devices. In practice, usually with a permanent magnet control the two metal sheets turned on or not, it is also called a magnetron.
Module Description:

1. The reed needs and with the use of magnets, in a certain sense the magnetic force, will form a conduction state, the module output low, when there is no magnetic force, OFF state, the output high, reed and magnet sensing distance within 1.5cm beyond the dead or will not trigger the phenomenon;

2. DO module outputs can MCU I / O port is directly connected, the device can be detected by dry reed pipe trigger state;

3. DO output terminal and relay module IN terminal connected to form a high-power reed switch, high voltage direct control.
