Sensors using giant magnetoresistance, where the resistance change for a given field is large enough to detect a modest magnet at a useful distance. For position, proximity and current sensing.
Sensors using tunnelling magnetoresistance, with high sensitivity and low power draw. Suited to precise angle and position measurement in small packages and to detecting weak or distant fields.
Magnetic sensors with signal conditioning and a digital interface already integrated, so the host reads a value rather than a millivolt output. For angle, position and current sensing in embedded systems.
Magnetically actuated switches and packaged proximity sensors for position and limit detection, with no power drawn until the field arrives. Several package and mounting styles for automation and security work.
Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
Magnetic field sensors come in four types: GMR, TMR, reed-based and smart devices carrying conditioning and a digital interface on board. All of them sense position, proximity, angle or current without mechanical contact.
