Reed Switch Technology
Standex-Meder offers the most comprehensive listing of reed switches that cover the majority of low power switching requirements. Reed relays and
reed sensors both use the reed switch as the heart of their switching mechanism. New applications continue to arise at a signicant pace for both
products because of the reed switch’s unique switching capability. What is driving these new applications is the ever broadening of new reed relay,
reed sensor and uid level designs by Standex-Meder.
For example, Standex-Meder offers a reed switch where the overall glass length is only 3.7 mm long (GR150) - the smallest in the industry. These
small sizes pave the way for unique new applications in RF switching, medical applications and many more applications.
Because reed switches are hermetically sealed (glass to metal seal) they are impervious to almost all environments. This opens up a vast number
of applications where they are the only technology capable of meeting specic requirements where certain mechanical switches and semiconductor
switches are environmentally limited. Many thousands of reed switch applications currently exist with many more added on a regular basis. These
applications span across all the major market segments.
Our engineers are always available to discuss your design requirements where specialized packaging is available in a very economical manner.

Often times electronic equipment is required to carry out certain functions in potentially explosive atmospheres. To prevent potential ignition of
the explosive atmosphere via a spark or arc in these environments, all components must be selected very carefully. Components meeting these
requirements are generally referred to as intrinsically safe. These components must be tested such that they will not become an ignition point when
subjected to short circuits or adjacent component failures. They must also switch to a dened state when subjected to overload conditions.
Our 522-03-i, 525-03-0-i, 535-04-0-i, and 567-70-i Opto-coupler series are all ideal for this environment.

Inductive Technology Sensors
Standex-Meder Electronics manufactures custom inductive technology position,
motion and speed sensors with the following features:
Detect metallic objects without touching them -used for proximity sensing
applications such as speed sensors
Each project designed to exacting customer standards including the ability
to withstand harsh environments
Proven in appliance safety applications with thousands of cycles, and ex-
treme “under hood” automotive applications
Custom Proximity & Motion Sensing Components
Reed Technology Sensors
Standex-Meder Electronics incorporates our magnetic reed switches into a wide
variety of custom proximity sensors and switches. The reed sensors come in
hundreds of different sizes and shapes to meet a multitude of different applica-
tion requirements. Customers have the opportunity to work with our engineers
to design or select the best packaging concept that will line up with their ap-
plication.
Our unique and patented production process allows us to produce not only very
small reed switches, but when we incorporate these into proximity sensors the
result is a small sensor with big performance impact.
These ultra-miniature components allow big improvements in the performance
of diverse products within medical devices, security systems, safes, and indus-
trial control applications.

Custom Fluid Sensors - Level (Reed & Conductive), Flow & Pressure Differential
Fluid Level Sensors - Reed Technology
The uid level reed sensors sense level changes in liquid in an assortment of
liquid mediums. The sensors generally have an attached oat with an em-
bedded magnet that moves up and down on a encased stem where the reed
switches are housed. The reed switches will change their closure state when
the oat comes within their magnetic inuence. The closure initiates a sequence
of events alerting the change of the liquid level.
We offer an extensive selection of different reed sensor packages, switch
congurations, stem lengths, oat density sensitivities allowing for diverse
applications. Our engineers are ready to match custom designs to stringent
requirements.
Our reed sensors are used in the automotive industry to measure fuel, oil, brake
uid, radiator, windshield washer level, and other uids. They are also found in
recreational vehicles, such as jet skis, sensing oil and fuel levels. Wherever a
liquid exists or can accumulate, Standex-Meder offers a sensing solution.

HVAC/R Series Flood Prevention Switches -Reed Technology
Truly Reliable, Plug-N-Play and Hassle Free
Standex-Meder provides the HVAC industry with high performing Flood Preven-
tion Switches (FPS’s) that are easy to install and service. Our expertise and
capabilities allow for reliable innovations that prevent overowing that causes
damage to oors, walls, ceilings and the like. For example, if water levels in the
auxiliary or main drain pipe rose due to a clogged air conditioning condensate,
the switch shuts off the system.
Custom Fluid Sensors - Level (Reed & Conductive), Flow & Pressure Differential
Fluid Level Sensors - Conductive Technology
Standex-Meder manufactures state-of-the-art conductive liquid sensors that
detect changes in levels without the use of a oat. These sensors are used
generally in water based conductive uids when the application cannot use a
oat based system. Our conductive uid level sensors have a patented false
full protection and current level shift to indicate uid level. They guard against
electrolysis and conduction paths along the sensor packaging with high quality
performance. Applications include the measurement of syrups and juices in the
food industry, measurement of liquid soaps in washing applications, liquid waste
products, storm drains, bilge pumps, sump water, and many other functions.
Flow Sensors - Reed Technology
Standex-Meder designs and manufactures custom reed switch and magnet
based ow switches for specic customer applications. The designs often
include harsh environments, signicant durability requirements, and precise ow
rate switching. Designs can be intrusive or non-intrusive with multiple custom
packaging options for terminating and wiring and add-ons for temperature sens-
ing, salinity, and multiple trip points.
Utilizing our vast experience in reed switch application engineering, mechanical
packaging, and related manufacturing process, Standex-Meder provides quality
ow switching products for markets such as home appliances and pool/spa.
Pressure Differential Sensors - Reed Technology
Differential pressure sensors are utilized in the hydraulics industry to alert
equipment operators that their hydraulic uid lter has reached the end of its
life. Standex-Meder designs and manufactures many congurations of these
“lter bypass” sensors with options for custom connection methods, varying trip
and reset pressures, NO/NC/SPDT switch congurations, mounting and sealing
to the lter head.
The hermetically sealed reed switch contacts are more reliable in these applica-
tions than other technologies such as open mechanical contacts, visual pop-up
indicators, or snap action switch assemblies. The contact quality, switching life
and non-intrusive sensing arrangement of reed switches increases indicator
reliability. We partner with the customer to design and validate the custom
indicators to specic OEM requirements, often creating a proprietary product
line for each customer.

Magnets In Housings
Permanent Magnets
General Information
A Reed Switch requires either a permanent magnet or magnetic eld in
order to activate the switch, thus it is commonly called a Magnetic Reed
Switch. Magnets have reversible and irreversible demagnetization speci-
cations. Engineers should consider shock, vibration, strong external mag-
netic elds as well as high temperatures in their designs. All these factors
inuence the magnetic force and the long term stability in different ways.
Preferably the magnet is mounted on the moving part of the application.
Professional tuning of magnet and reed switch pairing can improve the
functionality of the whole sensor-magnet system.
We offer the following types of permanent magents:
AlNiCo (Aluminum Nickel, Cobalt, Iron and Titanium)
Rare Earth (SmCo and NdFeB)

conditions. Here is a sampling of custom assemblies:
Ideal for high current metering applications
Rogowski coils are wire wound “air” core toroids which are used to measure
AC current
The AC current that is measured creates a magnetic eld which induces a
voltage in the coil that is proportional to the change in current
This innovative technology has been used in high current metering applica-
tions with a very high accuracy
