AVX 9176 Series allows devices to connect to a PCB without soldering.

AVX Corporation has developed a standalone surface mount discrete wire IDC contact and cap component that allows a range of devices to be connected to the PCB without soldering. The connector eases design constraints by enabling wires to be simply inserted into the SMT contact with a small tool.  In LED lighting applications, these contacts are used to bring power and signal onto the PCB and to enable lighting designers to daisy-chain multiple boards together in long strings to increase light output.

The 9176 Series of surface mount insulation displacement connectors were originally developed for harsh environment automotive and industrial market applications.  This industry proven contact system is approved to automotive levels for shock, vibration, and temperature cycling, further underlining its reliability and robustness.


The single 9176 Series contact and cap accepts 18 to 24 AWG wires with an insulation diameter ranging from 1.1 to 2.1mm. Dual beam contacts support a 10A current rating and the large SMT solder base provides high levels of stability on the PCB. The optional locking strain relief cap acts as the termination tool for severe vibration applications.

Supplied on tape and reel and compatible with industry-standard SMT placement equipment, the devices feature phosphor bronze contacts with tin over nickel plating, while the insulators are made from UL94-V0 Nylon 46. Operating temperature is -40ºC to +125ºC.
