Product details

12-Circuit Plug Housing for Mini-Fit Jr Power Harnesses

Contacts are ordered separately (crimp terminals, male pin type); the housing itself is natural PA66 nylon, rated UL94 V-0 for equipment inside an enclosure.

The crimp termination accepts the 5559-series male pin terminals — no contacts ship with the housing, so the BOM must list the terminal separately. The locking ramp engages audibly on full mate; no secondary TPA retainer is used on this series, so terminal seating depth during crimp insertion is critical.

Frequently asked questions

Does 0039013129 come with contacts?

No — the listing explicitly states contacts are not included. The male pin crimp terminals must be ordered separately from the Mini-Fit Jr 5559 terminal series.

What is the mating connector for 0039013129?

The mating half is a Mini-Fit Jr 5559 receptacle housing with the same 4.20mm pitch and dual-row layout. The exact order code depends on circuit count and keying.
