Product details

The 3-644695-2 is a 2-position, single-row unshrouded header from TE's MTA-100 series. The unshrouded design means the male pins are exposed — no shroud to guide or polarize the mating half, so alignment relies on the connector body keying.

Tin-Plated Contacts for Low-Cycle Interconnects

The 150 µin thickness provides a robust wear layer for the expected mating cycle life of this connector class.

Through-Hole Mount with Kinked Pins

The header terminates via kinked pins soldered into plated through-holes.

What is the mating connector for the MTA-100 2-position header?

This unshrouded header mates with MTA-100 IDC receptacles or crimp housings that accept 0.100" pitch contacts. The mating half must be a 2-position receptacle from the same series.
