The 1-179958-4 is a wire-to-wire connector from TE Connectivity's AMP Nano-Universal MATE-N-LOK family. This connector system is engineered to provide a reliable, compact solution for low-level signal and power applications. Its small size makes it an excellent choice for high-density interconnect challenges in space-constrained electronic devices.

This specific part number typically refers to a fully assembled, two-piece, plug and receptacle set with a specific number of positions (commonly 2 to 6 circuits), pre-loaded with terminals and wires.

Key Features & Benefits:

• Compact 3.96mm Pitch: Offers a smaller alternative to standard .062" or 1.57" pitch connectors, enabling higher packing density on PCBs and in wire harnesses.

• Fully Polarized Housings: Ensures correct mating and prevents damage from incorrect insertion.

• Positive Latch System: Features a secure, audible "click" upon mating, providing a reliable connection that resists vibration and unintentional disconnection.

• Funnel Entry Design: Guides terminals for easy and damage-free mating.

• High-Temperature Housing: The nylon housing is rated for elevated operating temperatures, suitable for a variety of demanding environments.

• Pre-assembled: This part number is often supplied as a ready-to-use, crimped wire-to-wire assembly, simplifying inventory and assembly processes.

Applications:

This connector is commonly found in applications requiring reliable, compact interconnects, such as:

• Appliance Controls: (e.g., washing machines, dryers, dishwashers)

• HVAC Systems: (Furnace controls, thermostats)

• Industrial Controls: (PLC I/O, sensors, small motors)

• Power Supplies & Converters

• Business Machine Internal Wiring

• Dielectric Withstanding Voltage: 1500 VAC

Important Note on Part Number:

The full part number is 1-179958-4. In TE's numbering system:

• 1-179958 is the base number for a specific housing style and configuration.

• -4 is the suffix that often indicates the number of positions/circuits (e.g., -2 for 2-position, -4 for 4-position), reel quantity, or color. In this case, -4 most commonly denotes a 4-position/4-circuit connector set.

Associated Parts:

• Crimp Terminals: Parts like 1-175218-* (for wire sizes) are the crimp terminals used with these housings.

• Headers: For wire-to-board applications, corresponding pin headers are available (e.g., 1-179966-*).
