Informação do fabricante:
This is the terminal for the polarized KK connectors and headers for your perf board/PCB projects. Use these connectors for power connections or any sensor/general connection to prevent users from connecting the peripheral incorrectly or reversed.
We regularly use a pair of needle nose pliers and a soldering iron to attach these pins. No special tools required. Be sure to order the mating header and housing!
Note: Price per unit.
