APEM Components, Inc. — a
leading manufacturer of high
quality miniature and industrial switches — introduces its new AV Series
pushbutton switches with an overmold
actuator. Complementing APEM’s line
of pushbutton switches, the AV Series
is ideally suited for applications pertaining to security panels, public kiosks,
vending machines, ATM machines,
handicap access control panels, and
heavy hydraulic lift equipment.
APEM’s highly secure AV Series
pushbutton switches feature a stainless steel actuator with thermoplastic
overmolding, available in a variety
of colors. Actuator styles include
illuminated ring or illuminated ring
and disc models.
Electrical and general specifications include power ratings of 50 mA
maximum at 24 VDC resistive load
and an electrical life of one million
cycles at full load. AV Series switches
have an initial contact resistance of
100 milliohms maximum and a
dielectric strength of 500 Vrms minimum ( 50 Hz minimum between terminals and 2.000 Vrms, 50 Hz minimum
between terminals and bushing).
Operating temperatures range from -
30°C to + 70°C. Additionally, the AV
Series is available in both solder lug
and straight PC terminals.
Material specifications include
brass or gold plated terminals, gold

or fiber data lines you have in place
now for USB devices,” said Fahrion.
“The fiber conductor models
bring an added benefit to the table,”
continued Fahrion. “Since fiber is
inherently immune to electrical and
radio interference, the fiber models
give you surge protection and optical
isolation. Many customers will
purchase this product strictly for the
isolation feature.”
B&B Electronics has copper
media models for USB Type 1.1 with
ranges of 50 meters and 100 meters. A
50 meter version for USB Type 2.0 is
also available. If fiber optic is your
media of choice, there are 10 meter
and 500 meter versions available.
The USB
standard calls for
a maximum
range of five
meters ( 16. 4 feet),
but you can stretch this useful protocol to over 100 meters using standard
UTP cabling, or as much as 500 meters
(1,640 feet) by using fiber cable. This
magic is made possible through the
use of the new Ulinx™ USB Extender
Modules from B&B Electronics.
“We’re not fudging on the USB
Standard,” says B&B Electronics
Director of Marketing (and past
Director of Engineering) Mike
Fahrion. “These are fully compliant
with the USB specification. They
deliver all of the benefits of USB,
including remote device powering,
plug and play operation, and cross-platform flexibility.”
Ulinx USB extenders are composed of two separate units: the local
extender and the remote extender.
The user supplies up to 100 meters of
Cat 5 cable or 500 meters of fiber
optic cable to connect the modules.
“It may even be able to use an existing
cable, allowing you to use the copper
