What it is and where it sits in the series
The Molex 1726722008 is the 8-circuit member of the Super Sabre 172672 series — a free-hanging single-row receptacle housing built around a 0.295 in (7.50 mm) pitch and rated 34 A per circuit. The connector uses a latch-lock fastening and accepts a Female Blade Socket contact via crimp termination. The housing ships as a body only; the contacts are ordered separately. Super Sabre housings sit in the mid-to-high current class for wire-to-wire power interconnects — the 34 A rating per circuit is well above commodity 7.5 mm pitch housings and reflects the beefier contact beam and larger cross-section the series uses to carry sustained current without a meaningful temperature rise.
What the key ratings mean
The 34 A per-contact rating governs the wire gauge the assembly must use — at that current level the wire is the current-limiting element, not the housing contact beam. Route your conductor selection to match or exceed 34 A before the housing becomes a constraint. Latch-lock fastening holds the mated half against vibration and pull-out without a tool — the retention force comes from the locking ramp inside the housing body. For applications with sustained vibration, verify the latch geometry is adequate or specify a secondary TPA (Terminal Position Assurance) clip on the contact side. Free-hanging in-line mount means the housing is not panel-mounted or board-stacked — it floats in the wire harness, typically used in engine-bay or chassis harness segments where the connector routes between two wire runs. The mounting orientation is determined by the latch polarity on the mating plug. Crimp termination on the contact side (the housing accepts the Female Blade Socket) is standard for field-terminated power harnesses — the wire is crimped to the contact, then inserted into the housing cavity. This requires matching Molex Super Sabre contacts ordered on a separate line; a BOM that lists only the housing code will arrive as an empty shell. Operating temperature range of -40°C to 125°C covers automotive engine-bay and industrial actuator environments — the polyamide (nylon) insulator handles the high end but note that long-term exposure at 125°C with sustained current will push the housing material toward its thermal limit, particularly if airflow is restricted.
What the 'Contacts Not Included' note means for your BOM
The listing explicitly states Contacts Not Included — this is not a packaging omission, it is a product structure statement. The Super Sabre 172672 series sells the housing and contact as separate line items. To build the assembly you need the matching Female Blade Socket contact for 172672, in the appropriate wire-gauge and plating grade for your duty cycle. Quote the housing and the contact together or the assembly will not arrive complete.
