Standex Electronics solved an automotive customer's problem and delivered a custom, fast design and quick turn molded liquid level sensor solution that fit the exacting needs for space and performance, while eliminating any potential for a battery coolant leak.
By integrating a float inside the tank and placing a reed sensor on the outside that can sense through the plastic wall, we were able to provide a fluid level sensor that didn't compromise the coolant tank's pressurized seal.
Fluid level sensors can be found in automotive applications from washer bottle fluid to engine coolant sensor applications. "The reed switch sensor technology works well."
Standex Electronics is a global leader in the design, development, and manufacturing of standard and custom Reed Sensors and standard sensors.
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's technical expert describes their 3D Magnetic Mapping capabilities used in reed sensor applications
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.
