Designed for a wide variety of harsh industrial applications, the vertical 9296 Series signals an expansion of AVX's series of single poke home WTB contacts. Providing maximum mechanical stability and wire retention, the WTB contacts feature high spring force, dual beam, and phosphor bronze contacts. The contacts avoid the added expense of an insulator and its associated assembly costs.

The contacts enable individual placement and both top and bottom wire entry for FR4 and metal core PCBs. Design flexibility is enhanced with the series expanding the range of options for bringing discrete power, signal, or ground lines onto a PCB.

The contacts support solid and stranded wires ranging from 18AWG to 24AWG, current ratings ranging from 7A to 12A, and temperatures ranging from -40°C to +125°C. They are designed for use in smart grid meters, breakers, and panels; solid-state lighting (SSL)/LED bulbs, fixtures, signage, and streetlights; machine controls, including motors, drives, solenoids, sensors, fans, and pumps; and commercial building controls such as security and fire sensors.

“Our new 9296 Series vertical top or bottom entry contacts provide designers with a robust, reliable, and repeatable wire-to-board termination process that replaces both expensive two piece connectors and the labor intensive process of hand soldering wires to PCBs,” commented Tom Anderson, Product Manager at AVX.

RoHS-compliant, the 9296 Series vertical WTB contacts are tape and reel packaged for automated SMT placement. Enabling simple wire insertion and twist and pull removal, the series also facilitates easy replacement. Voltage ratings for the series are based on placement distance between the individual contacts, and current ratings are dependent upon wire gauge: 18AWG = 12A, 20AWG = 10A, 22AWG = 8A, and 24AWG = 7A.
