Power system control chip. The DS1831 MultiSupply MicroMonitor
can track four system voltages simultaneously while providing 3.3V, 5V and master manual
reset inputs. An alternate version, DS1831A, substitutes a watchdog function for one of
the voltage monitors and master manual reset input, thus monitoring three system voltages
and processor operation. These capabilities allow custom control over individual power
supplies in multi-voltage systems. Dallas Semiconductor, Dallas, TX. 
Illuminated rockers. The R4 series of low cost illuminated
rocker switches offer a choice of colors and markings. Neon- and incandescent-lamp
versions are available in four different lamp voltage options. The series has quick
connect termination, as well as 10A @ 250V, 15A @ 125V AC ratings. They are listed for
service under UL, CSA, VDE, Semko, Nemko, Demko and Fimko listings. E-Switch, Brooklyn
Park, MN. 
pH controller. Dual 5A independent relays in the model 2200P
microprocessor-based controller can be individually programmed for true bi-directional
control. Relay A has an additional attribute to avoid overshooting -- a common problem in
chemical mixing and batch processes. An adjustable timer produces a cycling time that
allows additives to mix completely before readings are re-taken. A third alarm relay can
energize in response to a system malfunction. AquaMetrix Inc, Markham, ON. 
Stainless steel solenoid valve. Available in orifice sizes
from 1/16- to 1-in., the stainless steel version of the Type 6223 Series proportional
solenoid valve have a nearly linear characteristic operating curve. The plug-on electronic
control unit can be mounted in any position on the internally-piloted valve. The unit
operates with standard input signals, 4-20 mA, and 0-10V. Zero-point suppression ensures a
tight shut-off, and an LED display provides function monitoring. Burkert-USA, Irvine,
CA.
Foam for electronics.ECCOSTOCK FPH is a high temperature,
rigid, foam-in-place urethane series for microwave and electronic applications. The
two-part liquid system fills cavities populated with sensitive electronics, providing a
lightweight finished product that is thermally insulating and vibration damping with low
dielectric loss. The series is offered in kits with densities of 2, 4, 6 and 10 lb/ft3.
Emerson & Cuming Microwave Products Inc, Randolph, MA. 
Smart
switch displays. These software-controlled pushbutton switches can be programmed to
display an infinite variety of text, still images or moving images. Grouped together, the
IS Series of switches are capable of displaying sequential information. The support
structure allows side-by-side horizontal or vertical mounting, and red/green backlighting
plus 36 x 24 pixel resolution allow the switches to be easily read in high or low light
conditions. NKK Switches, Scottsdale, AZ. 
Pressure sensor. Model 6000 OEM pressure sensors are
all-stainless-steel, high performance instruments suitable for applications such as
hydraulic and pneumatic cylinder pressures, compressors, chiller packages, etc. With a
compensated range of 0° to 70°C, 100 mV FS output and weld-free construction, the 6000
has a Molex connector as standard equipment, with an option for ribbon cable. Other
options include port design, voltage and current outputs. PTC Electronics Inc, Wyckoff,
NJ. 
Functional stereolithography. Somos 9100 Series resins are
optimized for use on argon ion laser stereolithography machines (such as 3D Systems
SLA-500) for producing ProtoFunctional polypropylene prototypes. Parts produced with the
resin are robust, functional and accurate, and have a transparent amber appearance.
Tensile strength, elongation at yield and Young's modulus are close mimics of
polypropylene. DSM Somos, New Castle, DE. 
Junction boxes. The line of multibox NAMUR junction
boxes and cordsets can eliminate multiple cable runs, simplifying and speeding up the
wiring of sensors and other discrete I/O devices used in hazardous areas. The boxes come
with one or more circuits per port, with common positive or isolated circuits. They are
fully encapsulated, have rugged nylon housings, and are available with PLTC-rated integral
cable or in quick disconnect versions. Turck Inc, Plymouth, MN. 
Distribution box. Rated to IP67 and available with 4, 6 or 8
ports in 4- or 5-pole versions, the MVP12 Passive Distribution Box reduces cable and space
required when wiring machines or control panels. The device allows for quicker and easier
hook-up of sensors, actuators, photoelectrics and valves. The box has a connector with
hi-flex cable suitable for cable track applications, plus LED power and signal indicators.
The connection housing design makes installation easier. Murrelektronik Inc,
Doylestown, PA. 
Embedded computers. The ELIN family of embedded industrial
computers has the ability to run third party and custom applications. The devices use
disk-on-chip technology, which eliminates moving media, making the unit suitable for harsh
factory floor environments. ELIN computers are encased in stainless steel, and can be used
where NEMA 4/4X and/or CE compliance is required, including washdown. The processor used
is a Pentium 223 MHz MMX. EXOR, Wellington, FL. 
Transfer pumps. The "K" series of high pressure
reciprocating pumps includes submersible units that handle semi-dirty liquids or liquids
with suspended solids. There are also end-suction centrifugal pumps for high-flow,
low-pressure booster spraying and transfer applications. Pumps in the series are all
constructed of stainless steel, in a process that provides uniform thickness of components
for greater strength, lighter weight and increased efficiency, at a cost on par with cast
iron units. CAT PUMPS, Minneapolis, MN. 
Self-clinching fasteners. These floating fasteners provide
load-bearing threads in thin metal sheets, and permit up to 0.030 in. adjustment for
mating hole misalignment. Available in steel or stainless steel, they are offered with
locking or non-locking threads. Uniformity of locking torque is equivalent to MIL-N-25027
specifications. Penn Engineering & Manufacturing Group, Danboro, PA.
