Erni Electronics has expanded its offering of IDC (insulation displacement contact) terminals, with new variants for stranded wires (AWG24/7 and AWG26/7) having been added to the existing offering for solid wires AWG24/1 and stranded wires AWG22/7. Wires with a maximum diameter of 1,1 mm (including isolation) can be handled.
The new parts, as well as the previously available AWG22 variants, are available in colours like natural, red, green and black. These new colour variants offer the designer the option to colour-code the layout so that mistakes during wire attach are mitigated. The very compact IDC terminals are ideal for reliable PCB connections and especially in space sensitive applications such as in lighting (LED, OLEDs, etc.), medical equipment, smart metering, headsets and a huge variety of mobile devices.
The new IDC-PCB terminals eliminate manual preparation (dismantling) of wires prior to termination. The dual IDC contact blades provide a reliable, gas-tight connection to the conductor wire with high contact reliability. This means that costly and unreliable hand soldering processes can be avoided in favour of discrete wire attachments that can be reproduced and processed reliably.
The overall dimensions (3,3 x 3,3 x 2,8 mm) and required PCB space are significantly smaller compared to other solutions. The integrated cap (housing) guides the wire into the dual design terminal, while also serving as a strain relief mechanism. Other features include versions with closed end (wire stop) or feed-through (daisy chain capability). Guiding latches in the contact element guarantee correct connection, whilst detents ensure a secure hold.
In spite of their compact dimensions, they can support a maximum current carrying capacity of 14 A (AWG 24/7 at 20°C) or 12 A (AWG 26/7). The IDC terminals are specified for an extended temperature range of -40°C to 150°C. They are supplied in tape and reel packaging (2000 pieces) to facilitate fully automated board assembly, and are suitable for backside reflow soldering on modern SMT lines.
