Magnetic Reed Switch Construction Magnetic reed switches are electromechanical devices that open and close electrical circuits in response to magnetic fields. Their construction is critical to their functionality and reliability. The following details outline the key components and configurations of magnetic reed switches. 1. Basic Structure A typical magnetic reed switch consists of two or [...]
What is a Magnetic Reed Switch and How does it Work? What is a Magnetic Reed Switch? A magnetic reed switch is an electromechanical device that operates by the presence or absence of a magnetic field. It consists of two ferromagnetic metal contacts, known as reeds, which are hermetically sealed within a glass envelope. The [...]
On and Off, Off and On: Magnetic Switches How are magnets used in switches, and why are magnetic-powered electric switches important? “On-Off” switches are about as ubiquitous as traffic lights, conventional light switches, and stop signs. Around the world, people frequently interact with these everyday and mundane — yet very important — tools. Something as [...]
1. What is a magnetic sensor? A magnetic sensor usually refers to a sensor that converts the magnitude and variations of a magnetic field into electric signals. Magnetic fields, as exemplified by the magnetic field of the earth (earth magnetism) or magnets are familiar yet invisible phenomena. Magnetic sensors that convert invisible magnetic fields into [...]
Magnets in Sensors Demonstrated Value of Magnets in Sensors and Everyday Uses Driving a car, talking into a microphone, inserting coins into a machine — these common, mundane activities may seem completely unrelated, but there’s one shared element at work that may not cross your mind: the presence of magnets. More specifically, magnets are present [...]
New Flexible Electrode: Low Resistance, High Stability, Stretchable How did fishing nets cross the border from the aquaculture industry to the field of wearable human-computer interaction? Inspired by artificial fishing nets, Li Runwei's team from Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, and Zhu Guang's team from University of Nottingham Ningbo, [...]
Important Progress in Ultrastable Stretchable Electrodes In Ningbo Materials Institute In the field of smart wearable electronics, stable and durable flexible stretchable conductors are still a great challenge. Especially in the process of collecting physiological signals of human epidermis, stable and stretchable electrodes can realize long-term and accurate signal collection. At present, it is difficult [...]
Flexible, Elastic and Biomimetic Sensitive Materials and Sensors Flexible electronics, known as one of the top ten emerging technologies in the 21st century, is bringing a new revolution in electronic technology, which will affect industries worth tens of trillions of dollars in health, medical care, manufacturing, and robotics. Sensors are like human "sensory organs", which [...]
Magnets for Sensors The line of magnets for sensors is designed to meet the requirements of non-inductive sensor manufacturers that need position, level, adjustment and distance detection. Magnets for sensors of equal dimensions offer constant switching through time at greater distances from the sensor. Aluminium or non-ferrous metallic walls do not compromise switching. Furthermore, they [...]
Injection Molded Magnet Material Specification Brochure injection molded magnets combine high magnetic strength with excellent physical properties to offer a variety of features and benefits including: High Magnetic Strength PLASTIC molded magnets offer the highest energy available in bonded ferrite, neodymium-iron-boron and samarium cobalt. The ferrite and SmCo materials are highly oriented during the manufacturing [...]
Applications for Magnetic Sensors Magnetic sensors are used in many industrial applications for contactless current sensing, linear and angular position, and rotation sensing. magnetic sensors are designed to provide superior performance in all of these applications. Magnetic sensor products are based on its unique MLU-patented technology. In contrast to Hall devices that generally have low [...]
Reed Switches vs. Magnetoresistive Sensors In a previous post we took a look at magnetic field sensors vs inductive proximity sensors for robot grippers. In this post I am going to dive a little deeper into magnetic field sensors and compare two technologies: reed switches, and magnetoresistive sensors (GMR). Reed Switches The simplest magnetic field [...]
