Frequently Asked Questions
Q: What wire gauges are compatible with the 3.81mm pitch screw terminal block connectors?
A: These terminal block connectors are compatible with wire gauges ranging from 28AWG (thin signal wires) to 16AWG (heavier power wires), making them highly versatile for both low-current signal connections and higher-current power runs up to 8A.
Q: Can I use these screw terminal blocks on an Arduino or DIY PCB project?
A: Yes! The 3.81mm pitch is a popular standard that fits many PCB footprints. They are widely used for Arduino wire connections, DIY universal boards, power modules, and LCD module interfaces — simply strip 7–8mm of insulation, insert the wire, and tighten the screw.
Q: What is the difference between the female connector and a full set?
A: The "Female 10PCS" option includes only the female housing/socket portion of the connector. If you need the mating male plug as well, please select the appropriate paired option or purchase the male plug separately. Check product variant descriptions carefully before ordering.
Q: Are these terminal blocks rated for high-voltage applications?
A: The connectors carry a continuous rated voltage of 300V and are withstanding-voltage tested at AC 1500V for 1 minute, making them suitable for a wide range of electronics and control applications. The EU LVD classification is above 50Vac / 75Vdc. Always follow applicable local electrical codes when wiring.
