What this housing is
The Molex 1726722003 is the 3-circuit receptacle housing in the Super Sabre 172672 series — a free-hanging, in-line female blade-socket housing rated 34 A per circuit at 0.295 (7.50 mm) pitch. The housing accepts the matching Super Sabre crimp blade terminal (ordered separately) and locks with an integral latch to resist vibration separation in harness assemblies. It is black polyamide (PA nylon) and operates from -40 °C to 125 °C.
34 A on a 3-position housing — what the rating means
At 34 A per circuit, this is a power-interconnect housing, not a signal-density part. The 0.295 (7.50 mm) pitch gives the individual female blade sockets enough spacing and cross-section to carry that current without excessive temperature rise in the contact — the PA nylon housing material handles the operating temperature range up to 125 °C. The latch-lock fastening keeps the mating half seated under the vibration profile typical in industrial automation and vehicle harness runs. The female blade socket accepts the matching Super Sabre male tab — confirm the corresponding header or wire-to-board male blade is specified in the same series before finalising the BOM. The contact termination is crimp, so wire gauge compatibility and the correct crimp tooling are determined by the terminal, not the housing.
Contacts are ordered separately
The 1726722003 ships as the housing only — no contacts are included. Every BOM line specifying this part must also call out the compatible Super Sabre crimp blade terminal. Omitting the terminal from the order is the most common sourcing error on this series.
