Free Info - Circle 752 Polyurethane elastomer. Merethane 4721 is a two-component, low-viscosity polyurethane elastomer that has been specifically designed for potting cable connectors where excellent resistance to salt water and fuel oils is needed. Applications include potting keypad sensors and repairs in the telecommunications industry. When cured, Metrethane 4721 becomes a soft, tack-free elastomer that can be used with embedded circuitry. The material offers the following properties: soft, tack-free, 15 Shore A durometer repairable elastomer; protects components from internal stresses; excellent shock absorbing properties; excellent performance in demanding thermal shock and thermal cycling tests; and excellent resistance to salt water and most fuel oils.

Textured powdered coating. Textra is a powder coating designed
for metal substrates. This technology provides a uniform appearance even when film
thickness varies. It is offered in a full range of gloss and texture profiles. Textra
simplifies the process of sorting and matching parts that must be coated at different
times, in different thicknesses, and even in different locations. It also allows users to
re-coat, maintaining the same gloss and texture and appearance. Morton Powder
Coatings, Reading, PA. 800-367-3619. 
Rocker switches. The KG series of switches is designed for
safety of operation under extreme environmental conditions -- like those experienced by
off-highway vehicles in the building, construction, and agriculture fields -- as well as
many other tough applications. Both illuminated and non-illuminated models are offered,
with a wide variety of standard mobile symbol marking or special customer marking made by
laser or hot stamping. APEM Components, Wakefield, MA. 781-246-1007. 
Pushbutton switches. The SIRIUS 3S family of metal and plastic
22mm pushbuttons is watertight IP67-rated. These low-profile pushbuttons fit securely in a
22mm hole, requiring no notching or holding to keep them from rotating after installation.
An installer merely tightens a single screw on the retainer, then snaps on a contact
block. The device can accept up to four contacts directly without a contact block holder. Siemens
Energy & Automation, Alpharetta, GA. 770-751-2241.
Plugs and connectors. These 15 A plugs and connectors feature
the exclusive PermaLock terminal with locking collar overleaf that "locks up" as
the contact tang tightens down on the wire, virtually eliminating the need to ever
retighten the terminals. The clamp insert allows the widest variety of cable sizes (up to
10-3SO) and types including flat, small diameter, and special jackets. Marinco
Specialty Wiring Devices, Napa, CA. 800-307-6702. 
Pressure sensor. The P571 is a high-stability, small-diameter,
stainless steel sensor designed for use in pressure transducer and pressure measurement
applications. Its thin-film metal strain gauge circuit enables variation of 0.1% per year.
Options include Hastelloy, 500 VAC insulation resistance, and integral sputtered thin-film
Ni RTD. The sensor's wide range reaches from 100 to 10K psi, with a temperature tolerance
of up to 200°C. SMD, Meriden, CT. 203-235-9330.
Gears with integral hub fastener. This series of 0.5, 0.8 and
1 Module 303 stainless steel spur gears feature the Fairloc integral hub fastener.
Eliminating marred shafts, the Fairloc permits frequent phase adjustment, timing and
position adjustment. The 20 degree pressure angle metric gears are stocked in 5 thru 8mm
face widths, and are designed to fit shafts that are 4 thru 10mm in diameter. Sterling
Instruments, New Hyde Park, NY. 516-328-3300. 
Sleeve gear couplings. These C-type couplings provide up to
2.5 million lbs-in (282, 000 Nm) of torque handling capacity. They are 60 percent of the
size and 50 percent of the weight of flanged-sleeve gear couplings with comparable
torques. Offered in 14 standard sizes with bore capabilities from 7/8- to 12.5-in, the
couplings absorb angular and offset misalignment, as well as end float. Lovejoy Inc,
Downers Grove, IL. 630-852-0500.
