Contact construction and wire range
The TE Connectivity 66507-9 is a stamped pin contact from the AMPLIMITE HDP-20 series, designed for crimp termination onto 24-28 AWG wire. The brass base material is plated with 30.0µin (0.76µm) of gold on the mating surface, which provides the cycle life and corrosion resistance needed for repeated field mating in D-subminiature connectors.
Crimp tooling and assembly note
For reliable crimp termination, use a tool designed for AMPLIMITE HDP-20 contacts in the 24-28 AWG range. The stamped pin geometry requires a four-indent or full-cycle crimp tool to achieve the specified wire pull-out force.
