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 [...]
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 [...]
TMR Sensor Magnets TMR sensor is an epoch-making magnetoresistance effect sensor which has been applied to industrial application in recent years. TMR sensor has a much higher resistance change rate compared to AMR and GMR sensor, thus obtained many merits include low cost and power consumption, high response frequency and sensitivity. SDM has also collected [...]
Magnetic Field Sensors - Contactless and reliable detection Today’s pneumatic cylinders are compact, reliable, and cost-effective prime movers for automated equipment. Unfortunately, they are often provided with unreliable reed or Hall Effect switches that fail well before the service life of the cylinder itself is expended. magnetic field cylinder sensors are based on non-contact, solid-state [...]
Magnetic Encoder Engine Technology An optical encoder uses light (optics) to identify unique positions for the encoder. A magnetic encoder uses the same principle to determine a position as an optical encoder, but it does it using magnetic fields rather than light. With a magnetic encoder, a large magnetized wheel spins over a plate of [...]
Magnetic sensors indirectly measure properties such as direction, position, rotation, angle and current by detecting the magnetic field and its changes. Compared to other direct methods, such as optical or mechanical sensor, most magnetic sensors require some signal processing to get the property of interest. They provide reliable data without physical contact even in adverse [...]
