Robust Connectors Sport 2.55mm Profile For Space-constrained Environments


Many industrial, medical, and transportation applications exposed to harsh environmental conditions need robust, high-reliability interconnect solutions to help protect electrical connections. One popular alternative for applications in harsh environments is insulation displacement connectors (IDCs).

For design engineers working in a wide range of high-density, space-constrained applications exposed to harsh environmental conditions, AVX has designed its new 9176-800 Series low-profile Wire-to-board IDCs featuring a 2.55mm profile.

The new connectors are designed to connect discrete 22–26AWG solid and stranded wires and leaded components to PCBs, or to connect PCBs together in a daisy chain configuration.


Rated for 300V, 4–6A, and operating temperatures spanning -40°C to +125°C, the series delivers high-reliability power and signal connections in space-constrained, harsh-environment industrial, medical, and transportation applications including: smart metering, sensors, building controls, portable monitoring and measuring devices, point-of-sale equipment, handheld inventory management devices, security systems, patient monitoring equipment, and LED lighting.

The connectors are available in a range of sizes extending from one to four positions in each wire gauge, and feature redundant, fatigue-resistant phosphor bronze contacts that provide gas-tight, cold-welded wire connections that are compatible with potting and overmolding encapsulation processes for environmental protection.

AVX claims that the new connectors reduce the Z-axis height of the next-lowest-profile insulated IDC connector, the 9176-400 Series, by 1mm, reduce the total overall volume of the Standard 00-9176 Series IDCs by more than 50%, and are the first industrial IDCs available in a 2.55mm profile.

The new 9176-800 Series low-profile IDC connectors feature a flat, integral, glass-filled Nylon 46 cap compliant with UL94 V-0 and designed for automated pick-and-place assembly, and enable simple, single-step termination.

New Device For Secured WiFi IoT Connectivity

To further ensure error-free termination, the one-position versions are also available in eight colors designed to match individual wires.

Current ratings are reliant upon AWG; the 22AWG connectors are rated for 6A, the 24AWG connectors are rated for 5A, and the 26AWG connectors are rated or 4A, and every connector in the series is rated for three-cycle durability.

Parts are packaged in tape and reel in quantities of 1,700, UL approval is expected in April 2018, and 28AWG versions are currently in development.
