AVX Corp. has released the first industrial poke-home connector available without a wire stop. The new 2.5-mm poke-home contact — the latest addition to its 70-9296 Series STRIPT insulator-less, single-position, horizontal, poke-home contacts — combines a low profile with a range of compatible wire gauges: 20–26AWG solid and stranded wire. It is the first in the series and on the market to offer variants both with and without a wire stop.
Designed for use in solid-state lighting (SSL), industrial machine control, sensor, smart grid, building control, security system, and other ruggedized, space-constrained board-to-board, module-to-module, and wire-to-board applications, both versions of the poke-home contact feature a closed, dual-beam, high-spring-force, box contact design with robust, fatigue-resistant, phosphor bronze contact beams and an integral centering guide, ensuring proper positioning and providing maximum mechanical stability and wire/pin retention strength. In addition, the variant without a wire stop allows traditional pin jumpers to pass through the back of the contact unrestricted, rather than halting their travel at the back of an insulator, effectively absorbing variable PCB and module mating tolerances in linear board-to-board applications.
The new 70-9296 Series 2.5-mm poke-home contacts are rated for 300 Vac based on contact spacing, 6–12 A based on AWG, five-cycle durability, and operating temperatures extending from –40° to 125°C. They are also mating compatible with competitors’ jumpers and are packaged on tape and reel for automated SMT placement.
“Our portfolio of single-position poke-home contacts is available in a wider range of sizes that accept a broader range of solid and stranded wire than every competing poke-home connector currently available on the market, and is the first to offer a contact without a wire stop for effective tolerance absorption and manufacturing relief in ruggedized, space-constrained SSL and industrial applications,” said Tom Anderson, product manager at AVX. “The most capable competing contacts currently accept a maximum of 22 AWG, while our industry-leading offering extends up to 20 AWG. Many competing contacts are also taller and don’t accept stranded wire without tinning, like ours do, and none of them currently offer a 2.5 mm profile or a version without a wire stop.”
STRIPT contacts provide simple, reliable, and cost-effective alternatives to larger and more expensive, but equally reliable, one- and two-piece insulated connector solutions, as well as inexpensive, but wildly unreliable hand-soldered connections. They surface-mount to PCBs, are compatible with solid and stranded wires, feature integral wire guides and — with the exception of one of the new 2.5 mm variant — a wire stop, and are currently available in five sizes: 1.7, 2, 2.5, 3, and 4 mm, all of which are UL approved, save for the new 2.5 mm variants, which are pending approval, but expected to be green-lit by mid April.
