Sensor ICs

Allegro MicroSystems (Worcester, MA) offers two new current sensor ICs for AC or DC current sensing. Both the ACS724KMA (5 V) and the ACS725KMA (3.3 V) are set in a high-isolation SOIC16 wide-body surface mount package that provides reinforced isolation. The differential sensing technology protects against interfering common-mode magnetic fields from adjacent current traces or motors. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.

Touchless Variable Gap Sensor

PIHER Sensors and Controls S.A. (Brighton MI), a Meggitt company, has introduced a two-piece magnetic Hall effect variable gap sensor that maintains stable electrical output and specified linearity on mobile shafts, despite radial and axial movement. A circular arc magnet is attached to rotating shafts or assemblies, such as boom loaders, skid steers, buckets, and hitch arms; the electronics module is attached to the chassis.
