The recommended torque is 6-8 in-lbs (0.7-0.9 Nm) to ensure secure fastening without damaging the PCB or the terminal.
While the datasheet specifies 20 AWG as the maximum wire size, it's possible to use larger wires, but it may require additional insulation stripping and may affect the terminal's performance. Consult with Keystone Electronics Corp or a qualified engineer for specific guidance.
To ensure reliable connections in high-vibration applications, use a locking screw or a screw with a nylon patch to prevent the screw from loosening over time. Additionally, consider using a wire with a higher strand count and a larger diameter to reduce wire fatigue.
The 1426-1 terminal is rated for operation up to 105°C (221°F). However, if your application requires operation above this temperature, consult with Keystone Electronics Corp or a qualified engineer to determine the terminal's suitability and potential derating requirements.
While the datasheet assumes FR4 as the PCB material, the terminal can be used with other materials, such as high-temperature FR4, polyimide, or ceramic. However, the terminal's performance and reliability may vary depending on the PCB material's thermal and mechanical properties.
