Ultra-Fit Power Connectors
3.50mm Pitch

Ultra-Fit Tangless connector is a wire-to-board system that offers
a 3.50mm pitch, a higher-current rating of 14.0A, and superior
design options for flexibility and efficient assembly

Features and Advantages
Multiple mechanical keying and color-coded options

Allow same-circuit, multiple connector use with
virtually no chance of cross mating. Color coding
provides visual indication of the proper mating
connector — enabling faster assembly

17% reduction in pitch over similar power connectors

Current-dense design saves PCB space.
Allows for smaller packaging without sacrificing
current‑carrying capabilities

Optional TPA (Terminal Position Assurance) retainer

Guarantees the terminal is fully seated in thehousing to reduce terminal back-out. Retains
terminal if main retention feature fails

Ultra low mating force terminal

Reduces operator fatigue and improves assemblycompliance for high-circuit applications

Positive-lock housing with anti-snag design

Ensures mated connector assemblies will not
accidentally disengage. Provides an audible click
while mating. Protects latch from damage due towire snags

Fully isolated terminals

Protect against potential damage of the header andreceptacle terminals during handling and mating

Terminal interface with six independent points ofcontact (split-box terminal design)

Offers redundant, secondary current paths for longterm performance and reliability
