Extreme environments are no match for the Grip-Tech family of ergonomic handheld enclosures. The NEMA 4, fire-grade, polycarbonate parts come standard in black or white. They also have interchangeable, tactile thermoplastic-elastomer (TPE) rubber side grips that are available in eight standard colors or in a custom color.
Molded with polycarbonate material, the Grip-Tech family will withstand extreme impact even at cold temperatures. The fire-retardant UL 94 V2-rated material will self extinguish after 30 s, making the enclosure useful for high-voltage applications. The NEMA 4 one-piece molded sealing gasket comes standard and protects against water.
Six stainless-steel screws seated in brass inserts eliminate traditional plastic boss striping, so the enclosure can be taken apart countless times if required. Snap-in battery holders accommodate two AA, four AA, one 9-V, two 9-V, or no battery configurations. The sealed screw-on battery door keeps water out. All styles are available with industry-standard LCD windows. They also have a recessed top that suits use with a membrane keypad or label.

Multi-Seals Inc. offers a free engineering sample kit of its Uni-form epoxy preforms. The kit includes a variety of epoxy preform configurations along with an information pack. Epoxy preforms are an alternative to liquid epoxy for high-volume, high-quality epoxy sealing applications, and they're made of resins that are solid at room temperature. When heated, they melt and cure, forming a consistent seal that protects components from dust, moisture, oil, flux, solvents, conformal coatings, and other contaminants. Uni-forms are available in a wide range of shapes, sizes, and materials to accommodate diverse applications. Learn more at www.multi-seals.com.
Gap Filler 3500S35 is a thermally conductive, liquid gap-filling material from the Bergquist Company that features high thermal performance (3.6 W/m-K) and excellent softness. This two-component gel-like material can be cured either at room or elevated temperature. The material is good for interfacing fragile components to a universal heatsink or housing. Once cured, it's still a low-modulus elastomer that helps relieve CTE stresses during thermal cycling, but it maintains enough modulus to prevent pump-out from the interface. Gap Filler 3500S35 will lightly adhere to surfaces, though it isn't designed to be a structural adhesive. For details, go to www.bergquistcompany.com.
