Overview
The 3-641215-4 is a 4-position, single-row straight header from TE Connectivity's MTA-100 series. Designed for wire-to-board connections, it features 2.54mm (0.100 inch) spacing and a friction lock mechanism to ensure secure mating in high-vibration environments. The through-hole pins are made of tin-plated brass, providing a reliable electrical path rated for up to 250V.
Why Choose This Part
The friction lock design prevents accidental disconnection without the bulk of a full latching shroud, making it ideal for space-constrained layouts. Its UL94V-0 rated polyester housing and wide operating temperature range from -55C to 105C ensure durability in demanding thermal environments.
Applications
Internal Power Distribution
Connecting low-voltage DC power rails from a main PCB to peripheral daughterboards or cooling fans.
Control Panel Interconnects
Linking front-panel switches, LEDs, and potentiometers to the main system controller via ribbon cables or discrete wire harnesses.
Industrial Sensor Wiring
Providing a robust, vibration-resistant interface for 4-wire sensors such as digital encoders or I2C modules.
