Product details

The Universal MATE-N-LOK system accepts both male and female crimp contacts, so the same housing can serve as either a plug or a receptacle depending on which terminal you load. The contact termination is crimp, which means no soldering on the assembly line — just strip, crimp, and insert until the terminal locks. For wire gauge and contact part numbers, refer to the TE Universal MATE-N-LOK application tooling drawing; the housing itself accepts the standard contacts for this series.

Mating and Fastening

The latch holder on the plug engages the mating half's locking ramp; the connection is vibration-resistant without requiring a secondary locking clip. The single-row layout keeps the mated assembly narrow, which helps when routing multiple harness branches through a tight conduit or grommet.

Frequently asked questions

What contacts work with TE 2178473-2?

The 2178473-2 accepts Universal MATE-N-LOK crimp terminals — both male and female contacts fit this housing. The contacts are ordered separately; the housing itself does not include them. Refer to the TE Universal MATE-N-LOK contact family for the correct wire-gauge variant.

What is the mating connector for 2178473-2?

The 2178473-2 is a plug housing that mates with a 3-position Universal MATE-N-LOK receptacle housing of the same series, such as TE order code 1-480424-0. The latch holder on the plug locks with the receptacle's locking ramp.
