Flat Cables

High performance flexing

The Leoni-HPF series of flat cables are tailor made to be specified for 50 million or more flex cycles over a small bend radius. The cables are insulated from fluoropolymers, which is intended to minimize the dimensions and the weight. Users may mix and match the individual conductors and cable components, while the hybrid designs allow for the integration of a range of components. Typical applications for the cables include linear drives, robotic systems, material handling, medical diagnostics, and automated pharmaceuticals. Leoni Tailor-Made Cable Enter 586

Syringe System

Applies adhesive

CHO-BOND(R) 584-29 now comes in a syringe system that is designed for more convenient mixing, improved application precision, and greater dispensing accuracy. The system features a pair of syringes-one filled with a hardener and the other with the company's CHO-BOND(R) 584-29 conductive adhesive-separated by a connector. After the compounds are mixed, one syringe is used to apply the conductive adhesive. For hard to reach places, it is possible to attach a needle to the dispensing syringe for an even increased accuracy. Chomerics, Enter 591

Concealed-Head Studs, Standoffs

Promote flush assemblies

PEM fastening systems can be mounted permanently in steel or aluminum sheets as thin as 0.062 inch/1.6 mm. Their self-clinching, concealed-head capability enables the side of the sheet opposite installation to remain smooth and unaffected by the fastening process. The studs are available in thread sizes #4-40 through #10-32 and M3 through M5, and in lengths 0.25 through 1 inch and 6 through 25 mm. Standoffs are available in thread sizes #4-40 through .25-30 and M3 through M6, and in lengths from 0.187 through 1 inch and 4 through 25 mm. PEM Fastening Systems, Enter 592

Dual Elastomer Shielding Gaskets

Increased assortment

Pressure-Sensitive Adhesive

Encapsulates display technologies

This dual-stage, pressure-sensitive adhesive was created to offer a controllable and consistent thickness of the adhesive for any display application. The product's first stage is a pliable PSA that is designed for instant bonding. The second stage exposes the PSA to UV light, which transforms it to a bonding agent that does not require post-head processing. The adhesive is able to be pre-cut to a specific shape and it is supplied in roll form to facilitate high-speed manufacturing. Applications include the encapsulation of rigid and flexible OLEDs, LCDs, electronic paper, as well as other display technologies. Adhesives Enter 594
