4-Position Receptacle Housing for Wire-to-Wire Splices
The 770337-1: The natural nylon housing accepts male or female crimp contacts and secures the mate with a locking ramp for vibration-resistant retention in harness assemblies.
Contacts Not Included — Plan Your Terminal Order
The 770337-1 ships as a bare housing only — the spec line explicitly states Contacts Not Included. You will need to order the matching crimp terminals separately. For the Commercial.093" series, the typical mate uses a 0.093-inch-diameter pin or socket contact (such as TE part numbers 350536 or 350547, depending on wire gauge and gender). Confirm the terminal part number against your wire size before committing the BOM.
Mating Half and Locking Retention
This receptacle mates with the corresponding Commercial.093" Pin and Socket plug housing (e.g., TE 770335 series) that carries the same locking ramp feature. The locking ramp engages audibly on full mate and holds the pair together under vibration — a practical advantage in engine-bay or pump-motor harnesses where a loose connection would cause intermittent faults. The single-row, 4-position layout keeps the splice compact.
