Plastic-shell connectors designed for medical instrumentation applications

A series of plastic-shell connectors offer up to 27 gold-plated contacts in an 18-mm-diam body. The 405-series connectors can handle thousands of sterilization cycles, resist chemicals, and withstand operating temperatures of 200°C or greater. The connectors' inherently insulated construction provides electrical isolation and shock protection. They are available with or without integral shielding for EMI/RFI-sensitive applications. The connectors, which feature a SureGrip design for foolproof operation, intermate with the company's metal-shell line. W.W. Fischer Inc., 115 Perimeter Ctr. Pl., Ste. 1060, Atlanta, GA 30346.

PTFE surface coatings offer controllable thicknesses down to submicron levels

A technological advance in thin-film surface coatings allows the low-temperature deposition of pure PTFE. The thickness of the molecularly bonded coatings can be controlled down to submicron levels. The result is a thin-film surface coating with good adhesion, electrical, and mechanical properties. It can be applied to most materials and a high-temperature cure is not necessary. No overspray or high buildup are required when using the coatings in tight dimensions. Typical applications include release, barrier, friction, and device coatings. Advanced Surface Engineering Inc., 5320 Enterprise St., Ste. L, Eldersburg, MD 21784.

Nylon compounds suitable for a variety of medical product applications

Flexible nylon compounds are capable of filling a void in flexural modulus data between 80,000 and 120,000 psi, while remaining dimensionally stable with minimal postextrusion shrinkage. The Fostalon 5000 compounds are fully compatible with radiopaque fillers such as barium, bismuth, and tungsten, making them suitable for such medical applications as catheters, hubs, and shafts. The compounds resist hydrolytic degradation and can accept standard marking and imprinting inks. Foster Corp., 329 Lake Rd., Dayville, CT 06241.
