Reed Switch Sensor Working

Additionally reed switches can work with a variety of voltages loads and frequencies as the switch functions simply as a connected or disconnected wire.

Reed switch sensor working.

Reed switches like this are called normally closed nc normally switched on so electricity flows through them most of the time. It contains two ferromagnetic nickel and iron reed elements in an evacuated hermetically sealed glass tube to minimize contact arcing. Reed switches feature incredibly high reliability for a mechanical switch and they re able to. To be more precise a reed switch working is initiated when a magnetic force is brought near it which results in the required mechanical switching action.

Alternatively you ll need supporting circuitry to enable hall sensors to do their job. Fundamentally a reed switch is a magneto mechanical relay. Operated through a non magnetic material sensors can be developed with such sensitivity that they can be embedded deep within an assembly out of sight. No mechanical wear because there is no physical pressure applied to the switch there is no mechanical wear and tear.

How reed switches work. There are many advantages for using magnetically operated reed sensors including. Advantages of using reed switched. You can also get reed switches that work the opposite way.

The contacts are usually normally open closing when a magnetic field is present or they may be. In its simplest and most common form it consists of a pair of ferromagnetic flexible metal contacts in a hermetically sealed glass envelope. When an axially aligned magnet approaches the switch its magnetic force closes the reeds. In stock and ready to ship.

The two contacts are normally snapped together and when you bring a magnet up to the switch spring apart. Choose from our selection of reed switches including magnetically actuated switches magnetic contact alarm switches and more. The simplest magnetic field sensor is a reed switch.
