Magnet sensors monitor lids and doors
The HGDE series reliably detects the opening and closing of lids and doors on consumer equipment such as mobile phones, notebooks and digital camcorders.
Alps Electric has released the HGDE family of magnetic sensors with switching output to detect opening and closing of lids and doors on consumer equipment such as mobile phones, notebooks and digital camcorders The surface-mountable devices are available in three versions: the MAP (mould array package) type, on which terminals are positioned on the reverse of the component, the SON (small outline nonleaded) type, on which terminals extend from the side of the component for easier mounting and the SOT23 (small outline transistor) type

TACT switches slim to compact applications
Alps Electric has released the industry's thinnest double-action TACT switches for applications such as shutter buttons for digital still and video cameras.
This package also has its terminals on the side.
The sensors measure 1.1 x 0.9 x 0.55mm (MAP), 2.1 x 2.1 x 0.75mm (SON) and 2.9 x 2.8 x 1.1mm (SOT23).
They have an operating magnetic field of 2.0mT or 3.0mT.
They are designed for power supplies of 1.6 to 3.6V.
Their typical current consumption is only 3.0uA at 1.8V.
They are available with one-way only magnetic field sensing (single polarity/single output), two-way magnetic field sensing in either direction, output through one signal type (dual polarity/single output) and bi-polar magnetic field sensing in either direction, each with its own output signal (dual polarity/dual output); this function is only available for the types MAP and SON.
