Nano-Fit Connectors

Nano-Fit Power Connectors deliver fully protected header terminals, a small pitch size color-coding/keying options that ensure proper mating and terminal position assurance (TPA) to reduce terminal back-out; available in Wire-to-Board and Wire-to-Wire configurations.

Product Highlights


Current:Pitch:Wire AWG:
Up to 8.0A2.50mm20 - 26

Features and Benefits


Prevents damage to the connector or terminals by avoiding misalignment:
Decreases assembly time and mis-mating errors with blind-mate interface (BMI) connector design

The smallest, fully-isolated headers in the market:
Deliver up to 69% PCB space savings

Optional TPA (Terminal Position Assurance) retainer:
• Ensures terminals are fully seated in the housing to reduce terminal back-out
• Retains terminals if main retention feature fails

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

Terminal interface with four points of contact:
Offers redundant, secondary current paths for long-term performance and reliability

SMT version enables use of multi-layer boards by eliminating the need for through holes:
• Opens up real estate on space-constricted PCBs
• Potentially reduces costs by enabling use of smaller PCBs with fewer drilled holes

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

Ultra-low mate force terminal:
Reduces operator fatigue and improves assembly compliance for high-circuit applications

Fully isolated terminals:
Protect against potential damage of the header and receptacle terminals during handling and mating

Retention tang and contact rib:
Maintains stable contact

SMT headers provide short electrical paths:
Deliver superior signal integrity performance

Terminals and headers available in gold and tin plating:
Delivers different cost options while meeting performance need

Overview


Power-application customers are faced with choosing between headers with exposed terminals that leave connectors susceptible to damage and large, fully isolated headers that take up too much space. Compact Nano-Fit Power Connectors provide design engineers with fully protected header terminals in a small package.

When design engineers use multiple headers with the same circuit size on one PCB, assembly becomes complicated due to possible mis-mating of a receptacle with the wrong header. Nano-Fit Power Connectors offer different mechanical keying options, enabling customers to reduce the risk of cross-mating while improving assembly speed with color-coding logic.
