172287 Series
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 the
housing to reduce terminal back-out. Retains
terminal if main retention feature fails
Ultra low mating force terminal Reduces operator fatigue and improves assembly
compliance 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 to
wire snags
Fully isolated terminals Protect against potential damage of the header and
receptacle terminals during handling and mating
Terminal interface with six independent points of
contact (split-box terminal design)
Offers redundant, secondary current paths for long-
term performance and reliability
Features and Advantages
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
