Reed Sensor Module Durable Stable Lightweight Reed Module For Copy Machine

Reed is a short dry reed, is a kind of passive electronic switch contact element has a simple structure, small in size, and easy to control, etc., the shell is generally a sealed glass tube are installed there are two flexible iron reed panels, also called metallic rhodium has an inert gas filling. Normally, two glass tubes made of reeds of special materials are separated. When a magnetic substance near the glass tube, under the action of magnetic field lines, the two-reed tube is magnetized and attract each other's contacts, the reed will approach to make a node communication circuit connected. After the external magnetic force disappears, two reeds separately due to their elasticity, the line also disconnected. Therefore, as a signal to control the use of magnetic field line switching devices, the reed can be used as a sensor for counting, spacing, etc. (in security system, it is mainly used for door sensor, window magnetic production), but also It is widely used in a variety of communication devices. In practice, usually with a permanent magnet controlling the two sheets on or off, it is also known as a "magnetron".

Module uses:
1 . The dry reed pipe needs a magnet, when detecting a certain magnetic force, will display the ON state, the module output level low; no magnetic, display OFF state, high level output, dry reed pipe and magnetic induction distance within 1.5cm, beyond this distance insensitive or will not trigger phenomenon;
2. The output end of the DO module can directly connect to the I / O port of the microcontroller, triggered by a single-chip microcomputer, can detect the state of the dry reed tube; it can detect the dry reed trigger state by SCM DO modules terminate the output connect the IN end of the relay, can dial high-power dry reed pipe switches, directly control the high voltage.
