SAN JOSE, Calif.--(BUSINESS WIRE)--TDK Corporation (TSE: 6762) is expanding its Micronas magnetic sensor portfolio with the CUR 423x sensors developed for current measurements in automotive and ...

Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders, a device providing the angle of a magnet attached to a mechanical shaft ...

This article introduces Allegro’s ACS71x current sensor integrated circuits (ICs) without concentrator that can control and minimize external magnetic field interference. These devices can boost ...

Allegro has added magneto-resistive sensors to its Hall-based range of current and magnetic field devices, for high-sensitivity high-bandwidth applications. The first product is a 5A 1MHz isolated ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Most Hall-effect and magnetoresistive (MR) sensors are fabricated on 200mm (8-inch) wafers using CMOS or BiCMOS processes.
