MPCO Magnets for TMR Angle Sensors

MPCO Magnets for TMR Angle Sensors MPCO Magnets for Tunnel Magneto-Resistance (TMR) Angle Sensors distributes a magnetic field to reduce angular errors. These magnets offer high-reliability and a magnetization to minimize the error of angle. The magnets for TMR angular sensors feature a high-robustness against the setting area between the magnet and TMR angle sensor. [...]

Applications for Magnetic Sensors

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 [...]

  • Strong TMR Sensor Magnets

TMR Sensor Magnets

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 [...]

Reed Switches vs. Magnetoresistive Sensors

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 [...]

  • Magnetic Field Sensors

Magnetic Field Sensors

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 [...]

  • Reed Sensors

Reed Sensors

Reed sensors are reed switches that are packaged within an external housing for simplified mounting/connecting and additional protection against environmental influences. These sensors are typically mounted in mechanical systems. A bare reed switch can easily be mounted on circuit boards. However, for an application such as a door security sensor, the reed switch needs a [...]
