FPS-B Series (HVAC/R) Liquid Level Sensor bracket model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary or auxiliary condensate drain pans. This model includes a custom bracket that clips onto primary or auxiliary drain pans. UL508, NEC and IMC compliant.

FPS-L Series (HVAC/R) Liquid Level Sensor elbow model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary or auxiliary condensate drain plugs. This model includes a custom elbow pipe fitting to accommodate easy installation to primary or auxiliary drain plugs. UL508, NEC and IMC compliant.

FPS-T Series (HVAC/R) Liquid Level Sensor tee model flood prevention switches are simple to install, easy to service and extremely reliable.

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.

We will present the reed sensor's technology, how they 'tie into' the applications, and show how they solve the application's problem. We will also present many of the applications and go into detail on some of them.

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.
