Understanding Resolution in Optical and Magnetic Encoders How the different types of rotary encoders work and what differentiates the performance of the many types available today. Rotary encoders are devices that convert rotary movement or angular position into analogue or digital signals for use within measurement or control systems. They can be classified in a [...]
Comprehensive Guide on Magnetic Encoder A magnetic encoder is an electromechanical device which converts motion into digital signals using a magnetic field. It provides feedback about position, speed, and direction to the controller. In today’s modern world of automation, position accuracy and feedback are important to ensure accuracy and reliability in every performance. This positional [...]
Hall Effect Sensor We could not end this discussion on Magnetism without a mention about magnetic sensors and especially the very commonly used Hall Effect Sensor. The hall effect sensor is a type of magnetic sensor which can be used for detecting the strength and direction of a magnetic field produced from a permanent magnet [...]
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 [...]
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 [...]
How Does Temperature Affect Magnetism of Magnets? - Magnets are used in daily life. They’re used in manufacturing, automobiles, security systems and electronics devices. Even the earth itself is a magnet. How does temperature affect the magnetism of magnets? To understand temperature effects, we need to look at the atomic structure of the elements that [...]
Hall Effect Sensor Magnets Let MPCO help choose the magnet to best suit your specific sensor application requirements. We have experience designing around the effect of environmental conditions, temperature, shock, vibration, corrosion resistance, magnetic stability, manufacturability, form factor (and more!) related to the use of magnets with sensors and can help optimize the performance of [...]
