What This 2-Position Plug Housing Is
The TE 2-1747050-3 is a 2-position plug housing from the Grace Inertia, GIC series, designed for free-hanging (in-line) wire-to-wire or wire-to-board applications. The 7.80 mm pitch is unusually wide for a 2-circuit connector, which means the housing can accommodate larger wire gauges and provides generous creepage distance between adjacent circuits.
Contacts Are Ordered Separately — Plan Your BOM
The listing explicitly notes Contacts Not Included. This housing accepts tab-type crimp contacts (male terminals) that must be ordered as a separate line item. The contact termination is crimp, so the harness builder needs the matching TE crimp terminal for the wire gauge being used, plus the appropriate crimp tooling. For a production BOM, add the terminal part number and the housing as two distinct line items — the housing alone is an incomplete assembly.
Mating Half and Keying
This plug housing mates with the corresponding Grace Inertia GIC receptacle housing (female connector) of the same 2-position, 7.80 mm pitch configuration. The latch lock on the plug engages with the mating receptacle's locking feature for a vibration-resistant connection. No keying or polarization is specified beyond the latch lock — verify the mating receptacle's orientation before committing the harness design.
Lifecycle and Sourcing
The part is RoHS compliant. No official second-source or cross-reference is recorded, so the BOM should reference this exact TE order code.
