GENERAL DESCRIPTIONS

MRX1550H series are monolithic ICs with built-in MR magnet resistive

element and CMOS switch. It becomes the non-contact switch with low

current consumption, high sensitivity and reliability which is combined

with magnet.

A horizontal magnetic field parallel to the electrode of the package can

be detected by an arbitrary polarity. (N pole ⇔ S pole)
