About this item

  • ▷【Easy to Control】 ：The reed switch normally open is a passive electronic switch component, with a simple structure, small size, easy to control and so on
  • ▷【For Magnetic Field】： As a for controlling the magnetic field line switching device, the reed switch normally open can be used as a counter, and it is also widely used in various communication devices
  • ▷【Effective & Functional】：The reed switch normally open is clean, the waveform is good, and the driving capacity is greater than 15mA. The output form is a digital switch output (0 and 1) with fixed bolt holes. The PCB board is small in size for easy installation
  • ▷【Wide Application】: Wide voltage comparator LM393 is used in SPC exchange, copier, washing machine, refrigerator, camera, disinfection cabinet, door magnet, magnetic window, electromagnetic relay, electronic scale, level meter, gas meter, water meter, etc
  • ▷【Usage Principle】： Generally, two glass tubes made of special material reeds are separated. When the magnetic substance is close to the glass tube, under the action of the magnetic field lines, the two reed tubes are magnetized and attract the contacts to each other, and the reeds will be pulled together, so that the circuit of the connection node communicates. After the external magnetic force disappears


Product Description

4 pcs/Set Reed Sensor Module
B07S58HH3Q

Module USES:

  1. The dry reed pipe need magnet, when sensing certain magnetic force, will show ON state, the module output low level; no magnetic, show OFF state, output high level, dry reed pipe and magnetic induction distance within 1.5 cm, beyond this distance ,insensitive or will not trigger phenomenon;
  2. The module DO output end can connect directly to microcontroller I/O port, triggered by single chip microcomputer can detect dry reed pipe status;it can detect the trigger state of the dry reed by SCM
  3. Modules DO output end connect the IN end of relay, can compose high power dry reed pipe switches, control high voltage directly.

DESCRIPTION

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 special 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, and so on (in the security system 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 control the two metal sheets turned on or not, it is also known as "magnetron."

I was really hoping these reed switches would work well for a project I am working on however that is not the case. Two did not work at all upon arrival and the others are not very reliable. I would avoid these and go another route in the future.

2 of the switches were broken in the packaging. There was loose glass in the sealed packaging for both of them. I tried them anyways, and they are both stuck in the on position. Another switch seemed okay till you go to use it. Once it activated once with a magnet, it stays stuck in the on position. If you thump it slightly with your finger, you can eventually get it to release and go to the off position. Only 1 out of the 4 in the package actually worked as it was supposed to.
