AVX Corporation has developed and is now sampling the 53-8702 Series, a first-of-its-kind, off-the-shelf, high-reliability wire-to-board (WTB) connection system for discrete 18–24AWG wire terminations.
- For electronics applications exposed to shock, vibration, high temperatures, and other harsh environmental elements, including vehicular computers, such as airbag, engine, and transmission control units
- Combines industry-proven insulation displacement contact (IDC) and press-fit or compliant pin technology in a single package to deliver robust, double-ended, cold-welded, and gas-tight WTB terminations
- Eliminate costly two-piece connector systems
- Improves implementation efficiency and reliability
- Enables problem-free conformal coating
- Enhances design flexibility
- Remains effective throughout life of a vehicle
- Features two phosphor bronze contacts per position, each of which exhibits superior fatigue resistance over extreme temperature and deflection ranges, and are currently available in five positions
- Rated for 6–10A depending on wire size, and 125V
- Operating temperatures span -40-125 C (-40-257 F)
- Redundant contact systems for enhanced wire retention and PCB attachment
- Offers ability to connect two PCBs that are in close proximity, but not in the same orientation or alignment location for a traditional board-to-board connector more reliably than FFC/FPC cables typically used to jumper between two zero insertion force (ZIF) connectors, especially in high-vibration applications
- Improved implementation efficiency over FFC/FPC connectors via use of multiple color-coded discrete wire gauges to achieve high current-carrying capabilities, which can facilitate easier and more traditional wire dressing and routing through a vehicle
- Compatibility with potting processes without any risk of ingress, unlike traditional, elastic-only contact systems, which are vulnerable to potting material ingress during both the potting process and thermal expansion
- Dual assembly methodologies allow for either pre-installation on a PCB during board build process, enabling wires to be inserted and pressed into place with any standard flat rock seating tool upon final assembly, or pre-installation on a wiring harness, enabling connector to simply be pressed into PCB upon final assembly
