NEC announced recently that it has successfully developed and commenced full-scale production on the world's thinnest class of magnetic sensor at just 0.35 millimeters. Known as the "MRUS61C", the new product will be used for power and backlight switches in folding mobile phones and notebook computers, detecting the opening and closing of these and other similar devices. The NEC MRUS61C adopts a unique structure formed by the layering of magnetoresistive elements on IC circuits, achieving the world's thinnest class of magnetic sensors at a thickness of 0.35mm. The MRUS61C delivers a 36% reduction in the mounting space required when compared with NEC's existing models.

At a compact 1.0mm × 1.6mm × 0.35mm NEC MRUS61C delivers a substantial increase in design freedom when mounting the product.
