Fluid Level Sensors for Automotive & Transportation

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."

Reed Switches for Smart Home Automation Systems

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”.

Reed Switch Technology

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

リードスイッチの構造及び原理 (JP)

リードスイッチ、リードリレー及びリードセンサーは弊社の基本的に大事な製品ラインとしてこの3種類の製品ラインではリードスイッチという共同的な核心素子が入ってあります。リードスイッチは磁石による磁場の原理で駆動されるのに ,この原理は1940 年代初アメリカのベル研究所によって発明されました. 作動原理はとても簡単です。,二つの端に強い磁性体の性格を持った金属リード素子を約何マイクロメーターのとても微細な間隔で重なるようにした後ガラス管に入れて密封させます. そしてガラス管の内部には不活性ガスが満たされます。この時に二つのリード素子はお互いに離れてる状態だったが外部から磁石による磁場が形成になりながら極と極が発生して両極性を持った二つのリード素子はお互いに引き寄せて結合するようになります

Reed Switch SMD Sensor & Magnet Actuation in 3-D

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.

리드스위치 구조 및 원리 (KR)

리드 스위치 리드 릴레이 및 리드센서는 본사의 가장 기본적인 중요한 제품군으로 이루어져 있으며, 이 세 가지 제품군에는 리드 스위치 라는 공통적인 핵심소자가 들어갑니다. 리드 스위치 는 자석에 의한 자기장의 원리로 구동되는데 ,이 원리는1940 년대 초 미국벨 연구소에 의해서 발명 되었습니다. 작동원리는 아주 간단하여 ,두 개의 끝단에 강한 자성체의 성격을 가진 금속 리드 소자를 약 몇 마이크로미터의 아주 미세한 간격으로 겹쳐지게 한 후 유리관에 넣고 밀봉시킵니다. 그리고 유리관 내부에는 불활성 가스가 채워집니다 이때에 두 개의 리드소자는 서로 떨어져 있는 상태였으나 외부로부터 자석에 인한 자기장이 형성이 되면서 극과 극이 발생하여 양극성을 가진 두 개의 리드 소자는 서로 끌어당겨 결합하게 됩니다.
