Reed Switches for Smart Home Automation Systems

Reed Switches work well with smart home automation systems because they draw no power compared to other magnetic sensing elements. They can be married to a wireless or Bluetooth technology and placed in remote battery powered door sensors or window sensors, or anything where you’re looking for movement or proximity. They’re a very cost-effective and robust component suitable for the home environment, requiring fewer connections resulting in longer battery life.

In today’s homes and also commercial properties, there’s an increased necessity for control to improve efficiency and productivity. And with that control, you have different products that measure temperature, water levels, security, and locks, so within those products reed switches play a major role in making them “smart”.

Standex Electronics is a global leader in the design, development, and manufacturing of standard and custom Reed Switches.

Product Training Module – Reed Switch Overview

Welcome to Standex Electronics' Reed Switch Technology training module. This module will explain the functionality, unique features, structure, and crucial manufacturing and design element to reed switch technology. This module will also explain some basic switch parameters as well as describe basic reed switch operation along with a few applications.

Product Training Module – Reed Switch Magnet Interaction

Welcome to Standex Electronics' 'how magnets and reed switches interact with each other forming a sensing function' training module. This module will define key terms for magnets and reed switches. The module will also describe how the positioning of the magnet's north and south poles relative to the reed switch, produces different magnetic field arrays. Understanding these magnetic field arrays will give insight into how the magnet and reed switch form their sensing function.

How a Reed Switch Works

The Reed Switch is the core element in Reed Sensors, Level Sensors and Reed Relays. A magnetic contact switch consisting of two ferromagnetic blades are hermetically sealed inside a glass tube. The glass tube is filled with a high purity inert gas. Under non operating conditions the reed switch contacts do not touch. Standex Electronics is leading the way in reed switch manufacturing...

Reed Switch SMD Sensor & Magnet Actuation in 3-D

A Reed Switch Sensor on a surface mount PCB assembly shown in 3-D with actuating magnet. When viewed in three dimensions, the magnetic flux lines emanating from the magnet look like a beer barrel keg; and also in three dimensions, with the magnet parallel to the reed switch, the center magnetic lobe array looks like a donut and the two outside lobes look more like a boxer's punching bag -- the kind hung from the ceiling. Essentially the fields from the magnet and the fields for the lobes are symmetrical when viewed in three dimensions. As seen in two dimensions, when the magnet is brought into one of the lobes the reed switch contacts will close. Now, as seen in three dimensions the magnet can be brought into the lobes in any spherical direction for contact closure to occur. Here the magnet is moved into the sphere of influence of the lobes of the reed switch showing the closure and opening when the magnet enters the lobes and passes through them, The change in lighting signifies the closing and opening of the reed switch contacts.
