hi, im looking for polarising keys for my generic dupont connectors.
ive come across 65762-001LF and look like they will work.
my question is are they sold by the strip (so 10 plus the runner) or by the individual plug.

i previously bought 499712-1 from TE and these came loose (no runner, and easy to lose)

This one will be 10 pieces on the runner.

thanks a ton
