[time-nuts] MS3106R10SL-4S connector question

[Robert Atkinson]

Hi,
John is correct. The plastic pin is used when a contact position is not wired. You put the unwired pin in first and then insert the plastic pin behind it, thick end first. It replaces the wire to seal that individual hole and also maintain correct seal pressure on the other wires. Blue for #16 pins, Red for #20. Not required if you don't need a full environmental seal.

It's what I said. A blanking pin for the hole in the rubber seal, except
that it's only for the seal, not the whole connector.
