Alps Electric Released Highly Reliable Magnetic Sensor Switching Output Type HGD Series Developed

    TOKYO, March 8 /CNW/ - Alps Electric (Pink Sheet:APELY) has completed
development of the HGD Series of Highly Reliable Switching Output Type
Magnetic Sensors, which detect the opening and closing of the covers of mobile
telephones and notebook PCs, etc. Sample shipments are to commence in early

    Recently, most mobile telephones are of the folding type, with an
increasing trend toward more compact and thin models. In addition, more
complex construction designs such as swiveling liquid crystal display screens
are being made continuously in an effort to accommodate a diversity of
potential applications. The shape and construction of mobile telephones calls
for parts that are not just small and compact, but that cater to a high degree
of engineering flexibility.

    This product uses a magnetic sensor with Highly Reliable Magnetic
Elements, which can detect the opening and closing of folding mechanisms as
well as doors and lids. These Highly Reliable Magnetic Elements can sense over
a wider area and with higher reliability compared to other magnetic elements.
By association the field of magnetic sensors is also extended contributing to
engineering flexibility in product design.

    In addition, magnetic field sensing is available in three variations. The
HGD Series comes in two types: the industry's smallest Mold Allay Package
(MAP) type, on which terminals are positioned on the reverse of the component,
and; the Small Outline Nonleaded (SON) type, on which terminals extend from
the side of the component to realize easier mounting. The versatility provided
by these two types can better accommodate a variety of product functions and

    Furthermore, our Highly Reliable Magnetic Elements maintain high signal
output in comparison with other magnetic elements. As a result, the HGD
Series-mounted signal processing circuit can be restricted to an absolute
minimum, contributing to reduced current consumption and the effective use of

    Principal Applications

    Detecting opening and closing in the folding mechanisms of mobile
telephones and notebook PCs., doors and lids of refrigerators, washing
machines and other goods.
