The BH Series is a High-Power Relay capable of switching up to 1 kVDC, while providing a breakdown voltage of 3 kVDC and higher across the open contacts.
Thanks to the integrated Electrostatic Shield and axial switch leads, the BH relay ensures High Insulation Resistance of 10 TOhm across open contacts as well as between coil and contacts, and thus very Low Leakage Current in the picoamperes range.
The outer Magnetic Shield protects the relays against a mutual interaction and therefore allows an assembly with higher density.
This variable Multi-channel Dry-switch design can be built with up to 4 switches Form A and, thanks to its features such as reliable switching behavior, long lifetime and Low Contact Resistance (ON-Resistance), it makes an ideal relay for precise testers, automated test equipment or an alternative for Mercury Relays.

AI Industry's stronger demand for power and test equipment drive reed switch, sensor, and relay use.
Ralf Maier speaks to the AI Industry's impact on Reed technology use. "We are continuously developing new products for all our three product lines. We have the reed switches, sensors and relays. The AI industry has a stronger demand for power, but also a stronger demand for test equipment. This test equipment is used around the semiconductor fabrication and our products, especially the reed relays, are used in unique test equipment around the world to support these industries. Reed technology is used in almost every market. I think in your daily life you come across reed products every day. They are used in appliances such as washing machines and fridges, but they also used in security products like door alarm systems. But then we just talked about the semiconductor test equipment. Many, many reed relays are used there.
And one of our biggest markets is transportation and automotive where the electric vehicles take a large market share. Obviously, the last few years were very challenging for all the industry manufacturers. We have 10 factories around the world, and we have some unique capabilities, but also capabilities we have in different sites. So, we can support our customers in all the major regions directly with our processes and products. So, our intention is to continue to grow and to diversify our product portfolio. We have a strong road map for all three product lines for the reed switches, the sensors and the relays, and we continuously invest into new processes to be more efficient. Standex Electronics is your partner for sensing and switching solutions across the globe. We enable an electrified future."

Headquartered in Kofu City, Japan it was previously branded as the OKI Sensor Device Corporation prior to being acquired by Standex Electronics, Inc., a division of Standex International. The new name of OKI Reed Switches is KOFU, A Standex Electronics Brand.
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.
Welcome to Standex Electronics' RF Reed Relays Part I training module. Reed relays have long been known to have the capability to switch and carry RF signals and fast digital pulses. Hardly anyone thought reed relays were capable of switching and carrying RF up to 20 GHz, because the reed switch's leads are composed of nickel/iron which has a relatively high permeability or (MU). However, 20GHz is now a reality at Standex Electronics. We will be presenting the reasons Standex Electronics and their design team have made this possible.
Welcome to Standex Electronics' RF Reed Relays Part II training module. This second RF presentation assumes you have already heard the first Standex Electronics RF Part I presentation. Understanding the simple physical layout of a reed relay makes it easy to design and rest reed relays for RF and fast digital pulse applications. RF is dependent on the physical layout or signal path it takes while going through circuits and the components that make up those circuits. We will show you how the physical layout of the reed relay will have a direct bearing on the RF signal's success going into and out of the reed relay. Coupled with the relay's physical layout, the materials making up the reed relay are also important.

Standex Electronics expert discusses reed switch technology and why reed switches play such an important role in many applications.
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.
