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" Glass Length: 14mm

• Dry reed compact structure, low weight, can be installed in extremely limited space, very suitable for miniaturization of equipment.
• Dry reed switch components are hermetically sealed in an inert gas atmosphere, never in contact with the external environment, long working life.
• Dry reed did not use the sliding element, it will not appear in all metal downgrade related metal fatigue phenomenon, in fact no limit to ensure that the mechanical life.
• Reed switches in the phone, 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 good application.
• Shear or bending reed lead foot must be extremely careful to avoid undue stress leaving the glass - metal seals were damaged. Appropriate clamping tool must be used
