What this housing is
The Molex 436801003 is the 3-position member of the Sabre 43680 series — a free-hanging in-line plug housing sized for 0.295" (7.50 mm) pitch and rated 18 A per circuit. It accepts male blade contacts via crimp termination (contacts ordered separately), and the locking ramp on the housing shell keeps the mating half seated under industrial vibration. Contacts Not Included — the listing is for the housing shell only. The matching crimp terminals (male blade) and the mating receptacle housing are separate line items, and the BOM buyer needs to confirm those positions are listed alongside this one. Insulation is polyamide (nylon), natural in color, with an operating range of -40°C to 75°C — adequate for most control-cabinet and machine-tool environments. Stacking direction is side-to-side on a single row.
What it mates with
This is a plug housing with male blade contacts — it mates with the matching Sabre 43680 series receptacle housing (which accepts the corresponding female crimp contacts). The locking ramp on the plug shell engages the latch on the receptacle. Wire gauge and crimp terminal selection depend on the current per circuit; the 18 A rating governs the minimum wire gauge for the harness builder.
