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.

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)

• Hard Ferrite

These are some of our most widely used models, others available as

required.
