AVX announces two series of WTW (Wire-To-Wire) connectors that deliver considerable cost and space savings in a broad range of industrial electronics designs. The 9286-200 series reduced thru-wire connectors and 9286-250 series reduced junction box connectors feature an active stainless steel spring contact with mechanical properties that allow it to provide maximum wire retention for 18-24AWG solid and stranded wire gauges.

Capable of accommodating simple strip-and-poke-home wire insertion and twist-and-pull extraction, which is especially beneficial in field installations, these high-spring-force stainless steel contacts also effectively replace the push-button activation mechanism that traditional two-piece plug-and-socket WTW connectors require for wire insertion and removal, enabling significant cost savings in an array of industrial power and signal applications, including: smart grid meters, breakers and panels; SSL fixtures, signage and streetlights; commercial building controls and security/fire sensors; and industrial machine controls such as motors, drives, solenoids, sensors, fans and pumps.

Tom Anderson, Connector Product Manager, AVX, commented: “Wire-to-wire connectors have been a mainstay in the industrial market for years. Until now, however, they’ve typically required crimp and poke wire terminations to connect discrete wires, which is effective with regard to pluggability and latching, but often prohibitive with regard to size and cost - especially in applications that will only need one or two wires replaced during a product’s lifetime. So, we designed our 9286 family poke-home reduced thru-wire and junction box connectors to fulfil this gap in the broad industrial market by delivering enhanced strength, flexibility and versatility, in addition to considerable cost and space savings.”

Both of these 9286 poke-home WTW connectors are rated for 300VAC and operating temperatures from -40 to +130°C, stand a mere 4mm high and measure a slight 16mm in length. Both series also feature a glass-filled Nylon 46 insulator (UL94V0), copper alloy fixed contact materials with tin-over-nickel plating and a durability of three cycles.

Available in one to six positions, the 9286-200 series reduced thru-wire connectors measure between 8 and 24mm in width and have three current ratings: 3A (24AWG), 5A (22 and 20AWG) and 8A (18AWG).

Available in four to eight positions, the 9286-250 reduced junction box connectors measure between 8 and 16mm in width and have four current ratings: 3A (24AWG), 7A (22AWG), 8A (20AWG) and 9A (18AWG).

Components are shipped in 1,000 unit quantities with a lead-time for the series of 8-9 weeks.
