Right-angle header for board-edge cable exits
The 640455-6 is a 6-position, single-row, right-angle through-hole header from TE's MTA-100 series. It mates with MTA-100 IDC receptacles or crimp-socket housings for a board-to-cable/wire interconnect.
Tin contacts and partial shroud for cost-sensitive builds
The 1-wall shroud protects the mating pins from one side while leaving the wire exit open.
Voltage and current: what the ratings mean
Rated 250 VAC — the insulation system (thermoplastic housing, 0.225" insulation height) supports this voltage in dry indoor environments. Current rating is not a fixed number: it depends on the wire gauge used with the mating terminal. For example, 22 AWG wire typically carries 4-5 A per contact, while 18 AWG may carry 7-8 A, always limited by the temperature rise at the contact interface.
