Overview

The TFM-110-02-L-D-LC is a high-reliability, 20-position terminal strip from Samtec Tiger Eye series featuring a 1.27mm (0.050 inch) pitch. This surface-mount header is designed with a shrouded four-wall construction and includes integrated locking clips for enhanced mechanical stability on the PCB. It is engineered for rugged board-to-board or cable-to-board applications where space is limited but high mating cycle durability is required.

Why Choose This Part

The Tiger Eye contact system is specifically designed for high-reliability and high-mating cycle applications. The 4-wall shrouded design prevents misalignment during mating, while the surface-mount termination and locking clips provide a robust mechanical bond to the PCB without the need for through-holes.

Applications

High-Density Board Stacking
Utilized in compact industrial electronics where 1.27mm pitch allows for significant space savings compared to standard 2.54mm headers.
Mezzanine Card Interconnects
Ideal for connecting daughter cards to motherboards in ruggedized embedded systems requiring a secure, shrouded connection.
Rugged Handheld Devices
The integrated locking clip (LC) option provides vibration resistance for portable equipment and mobile computing hardware.
