Overview

The 640456-2 is a 2-position, single-row straight header from TE Connectivity's MTA-100 series. This through-hole connector features a 2.54mm (0.100 inch) pitch and a friction lock mechanism to ensure secure wire-to-board mating. It is rated for 5A and 250VAC, making it a reliable choice for power and signal distribution in space-constrained designs.

Why Choose This Part

This header features tin-plated phosphor bronze contacts and a UL94V-0 rated polyester housing for robust performance across a -55C to +105C temperature range. The friction lock provides enough retention force to prevent accidental disconnection from vibration while remaining easy to disconnect for field service. Its 250V rating and 5A capacity allow it to handle more power than standard 0.1-inch break-away headers.

Applications

Internal Power Distribution
Connecting internal DC power rails to peripheral PCBs or cooling fans within an enclosure.
Sensor Interconnects
Providing a detachable interface for remote analog or digital sensors in industrial equipment.
Control Panel Wiring
Wiring user interface components like buttons or LEDs to a main control board.
Low-Voltage Signal Routing
Transferring logic-level signals between stacked or adjacent circuit boards.
