Sensors & Magnets | Introduction

Reed sensors use the reed switch as the heart of their switching mechanism. When paired with a permanent magnet they are an ideal method of sensing and detecting metal, movement, proximity, and liquid level and flow. Reed sensors come in hundreds of different sizes and shapes. And meet a multitude of application requirements. Additionally reed sensors are available in many contact forms and up to 100W rated power. Furthermore the reed sensor will perform billions of operations. But only if switching relatively low voltages and currents. Finally a reed sensor works by opening and closing its reed switch contacts in the presence of a magnetic field. For more on reed sensor operation check out our video "Reed Switch & Magnet Interaction". Or take a look at magnet interaction examples. Standex Electronics is a reed technology expert specializing in custom sensor packaging to meet you complex design needs. Please contact us to provide the optimal solution for your specific needs.

Bi-stable / Latching

A latching reed sensor is an extremely low power solution. These work very well in battery powered devices and other power critical applications. Latching or bi-stable sensors use magnetic biasing to open and close their contacts. The sensor contains one or more internal reed switches and/or permanent magnets. The internal permanent magnet moves the reed switch contacts closer together. But still the contacts remain in the open state. Because the magnet is only partially magnetized. While an external magnet opens and closes the switch by reversing the magnetic field. Hence the latching function. The contacts remain in their normally open or closed state until the magnetic field is changes yet again. The latching function can get tricky! So you'll need work with our latching sensor experts. They'll design a solution according to your specific application. Learn more...

Form B - Normally-Closed

A normally closed (SPST-N.C.) or Form B reed sensor represent the state of contacts before any magnetic field is applied to them in which they exist in the closed state. To open the contacts a magnet of opposite polarity is brought into the existing magnetic field cancelling the field from the existing permanent magnet. This in turn opens the contacts. The magnet must be carefully chosen so that its strength is strong enough to cancel the field from the permanent magnet, but not too strong that it overpowers the permanent magnets field, which could re-close the contacts. Furthermore, care must be taken in selecting the physical operate and release points. Knowing where these 3 magnetic lobes are is essential for proper sensor operation. Check out these animated Magnet Interaction examples showing the reed switches in their sensing environment.

Form C - Changeover

Changeover reed sensor products contain one or more single-pole double throw SPDT reed switches where a normally closed contact opens before a normally open contact closes. A changeover reed sensor is also referred to as a (Form C) reed sensor or break-before-make (Form C) which defines the sequence in which one reed switch contact opens its connection to another contact and then closes its connection to a third contact. Changeover reed sensors can also be used as a (Form B), normally closed reed sensor (N.C.) application. Check out our Magnet Interaction page to see animated examples of how reed switches are used in a sensing environment.
