Product details

7-Position IDC Receptacle for Discrete Wire Harnesses

IDC Termination and Wire Prep

No crimp tool or loose terminal handling — just a single IDC press. The 26-28 AWG range covers common signal-level wiring in control cabinets and sensor harnesses. The single-row layout keeps the insertion force manageable for hand-tool or bench-press assembly.

The 7-position count matches a 7-pin header; the natural housing colour helps field techs visually confirm the pair before mating. No keying or polarisation beyond the housing geometry, so verify the header's pin arrangement against your harness routing before committing the BOM line.

Frequently asked questions

What headers mate with the 173977-7?

The 173977-7 mates with TE CT series pin headers at the same 2.00 mm pitch, such as the 173976 series. The 7-position receptacle pairs with a 7-position header; confirm the header's mounting style (straight or right-angle) and pin length match your board-to-wire stack-up.

Is 173977-7 RoHS compliant?

Yes, the 173977-7 is ROHS3 Compliant, meeting the current EU RoHS substance restrictions for electronic equipment.
