The TE Connectivity 3-643818-2 is a factory-pre-assembled, 2-position wire harness from the industry-standard MTA-156 connector series. This part represents a specific, ready-to-use configuration designed for quick and reliable power and signal disconnection. It eliminates the need for manual crimping, providing a consistent and high-quality solution for internal wiring in a wide array of electronic and electrical equipment.

Key Features & Benefits:

Pre-Crimped & Ready-to-Install: Saves time and labor by arriving fully assembled, ensuring perfect terminations and eliminating the need for costly crimping tooling.

MTA-156 Interface: Features the reliable 0.156" (3.96mm) pitch MTA-156 connector, a proven design for discrete wire-to-wire and wire-to-board connections.

Fully-Insulated Receptacles (FIR): The female connectors are fully insulated, providing enhanced safety by preventing accidental contact with live terminals and offering superior strain relief.

Standardized Wire Gauge: Utilizes 20 AWG stranded copper wire, offering an optimal balance of current capacity and flexibility for many low to moderate power applications.

Positive Locking: The connector housings feature a latch that securely mates with standard MTA-156 posts, preventing accidental disconnection due to vibration or wire pull.

Color-Coded Wires: Typically features standard color-coding (e.g., Black and White) for easy polarity identification and circuit tracing.

Applications:

This pre-made harness is ideal for applications requiring a simple, safe, and removable connection:

Appliance Wiring: Internal power and control connections in washers, dryers, and dishwashers.

HVAC Systems: Connecting controls, sensors, and fans.

Industrial Control Panels: Providing easy-to-disconnect links between components.

Power Supplies: For internal and external power distribution.

Business Machines: Internal wiring for printers, copiers, and vending machines.
