The TE 1-1827864-4 is an 8-position, 2-row receptacle housing from the Dynamic D-1200 series, on a 2.50mm pitch. This housing is used in wire-to-board or wire-to-wire harnesses where a compact, polarized interconnect is needed — typical in industrial controls, automotive body electronics, and appliance power distribution.
Sizing the Housing for Your Harness
The 2.50mm pitch and 0.130" (3.30mm) row spacing define the footprint for the mating header — confirm the header's PCB layout matches these centers. The polarizing key prevents mis-mating with non-keyed headers, so verify the key position on both halves. The housing accepts crimp terminals (not included) — order the correct TE Dynamic D-1200 female socket contact for your wire gauge (typically 20-24 AWG, confirm per contact datasheet).
