S-5701 B Series TMR Sensor ICs

ABLIC’s sensor ICs are compact and offer durability with a long life

ABLIC’s S-5701 B series of TMR sensor IC’s, with a TMR element and signal processing circuit are mounted and resin-molded on the same silicon, offering extreme durability. They are available in small, thin surface-mounted packages that can be mounted simultaneously with other components. These sensor ICs use a small TMR element that is 1/10 the size of that of a comparable reed switch. The small size magnets simplify placement which helps to reduce the size of the final product and improve design friendliness.
