The new 9175 connector from passive and connectors specialist AVX’s Elco Europe Division, now added to the portfolio of TTI, Inc., allows users to easily connect individual wires to a single row of contacts using IDC technology. Currently available as 2-and 3-way IDC connectors, the device is both low-profile (3.45mm) with a small PCB footprint (2 way: 5.0x2.5mm, 3 way: 7.5x2.5mm), saving precious space on PCBs. A dedicated single-wire insertion hand tool allows for quick and easy assembly.

Before assembly, 9175 series connectors are surface mounted to the PCB. Using the hand tool, 26 or 28 AWG solid/ stranded wires are inserted into the contact slot. This process cuts the insulation and enables the individual conductors of the wire to form a homogeneous joint. The shape of the moulding forms a restraint to the wire when fully inserted in the contact. Contact material is phosphor bronze, with 5 re-terminations achievable for each individual contact. The devices offer a current rating of 1A continuous through all contacts at 25 degrees Celsius (ambient), with a voltage rating of 125V, delivering a minimum insulation resistance of 100MΩ, and a maximum termination resistance of 20mΩ. The components feature an operating temperature range of -40 up to +80 degrees Celsius.

Due to ease and speed of assembly to the small volume intricate/flexible connections of high value devices, 9175 connectors can be used for connecting 2 or 3 wires between PCBs, in high volume consumer market applications, for example speakers, buzzers, microphones, vibration mechanisms. The parts are supplied in tape and reel packaging and are fully RoHS-compliant.
