Contacts and Plating Product Roundup  

This week’s Product Roundup highlights contacts and plating from leading connector manufacturers and suppliers.

Contacts and Plating

PRECI-DIP AS39029-rated contacts, available from PEI-Genesis, feature a patented reversed clip socket design which provides a smaller difference between insertion and extraction forces. They offer reduced dispersion of the force values, as well as higher redundancy of the contact points with 6 or 8 contact fingers. These PRECI-DIP contacts are qualified to AS39029 rating and are QPL listed.

Invented by Anderson Power in 1954, flat-wiping contacts reduce inventory costs, expand storage battery life, and simplify assembly in industrial battery applications. When engaged or disengaged, the contact surfaces over-wipe to self-clean the mating surface. The universal, genderless design features a sacrificial tip which confines damage to a non-conducting area when mating or breaking under load. The raised surface on the mating side also ensures secure and reliable connections. Rated for up to 10,000 mating cycles and usually silver-plated for enhanced corrosion resistance, flat-wiping contacts from Anderson Power deliver long-lasting performance in demanding industrial environments.

AP-TSS10 from I-PEX serves as a spacer and power terminal. Using AP-TSS10 with PCB SMT terminal AP-LT10 helps reduce potential damage to the PCB during screw fastening. AP-LT10 is rated for temperatures up to 125 °C, capable of handling currents up to 32A. The standard lineup supports an 8.5 mm board-to-board distance and M3 screw size, with customization available for different heights and screw dimensions.

Nicomatic’s DMM connectors feature high-performance machined contacts available in signal, power (up to 20A), and high-frequency configurations. These contacts are precision-machined from high-quality conductive materials and finished with corrosion-resistant coatings, ensuring long-lasting performance even under extreme conditions. Their design ensures reliable insertion repeatability, enhanced mechanical retention, and compatibility with harsh thermal and vibrational environments. Compliant with MIL-DTL-83513G and EN4165 standards, they are ideal for embedded systems exposed to high mechanical and electrical stresses, particularly defense, aerospace, and railway applications.

Rugged and time-proven, ept connectors’ specialty T-Com press-fit pins are asked for by name in the industry due to their exceptional press-fit performance. With in-house electroplating lines, ept can offer efficient, cost-effective manufacturing of completely customizable contacts tailored to meet the specific demands of an application. ept’s in-house quality standards guarantee that contacts are plated without soldering defects or flux residues. Many base material copper alloy options, including CuNiSi, CuSn6, and CuZn37, are available. The nickel barrier layer can be applied in thicknesses of 1.0 up to 4.0 µm, depending on performance needs, to ensure durable, optimized corrosion resistance. ept’s expansive menu of material finishes for surface plating offers flexibility in conductivity, mechanical strength, and thermal performance. With additional finishes available upon request, ept currently offers indium (In), gold (Au), gold over palladium-nickel (Au over PdNi), gold over nickel-phosphorus (Au over NiP), tin (Sn), tin-lead (SnPb), and silver-tin alloys (AgSn or SnAg), all fully adjustable in thickness. In addition to press-fit contacts, ept offers a variety of contact and pin designs, including blade terminals up to 9.5 mm wide and 1.25 mm thick for high-power applications.
