Applications
The TMM-110-01-T-S-SM is suited for board-to-board signal connections in industrial instrumentation, embedded computing modules, and RF evaluation boards requiring a reliable 10-circuit SMD header at 2 mm pitch. Its surface-mount design eliminates the need for through-hole drilling, simplifying PCB fabrication for single-sided and double-sided assemblies. The staggered pin geometry improves pull-out strength, which is advantageous in applications subject to handling stress during test and assembly.

Frequently Asked Questions
How does the staggered SMD pin pattern of TMM-110-01-T-S-SM improve mechanical solder joint reliability?
Staggered SMD pins distribute solder joint stress across a wider PCB footprint compared to a single straight row, reducing the risk of joint fatigue under lateral or pull-out forces. This mechanical advantage is significant in board-to-board assemblies subjected to handling at 10-contact density on a 2 mm pitch.
For which board-to-board signal interfaces is the 2 mm pitch of TMM-110-01-T-S-SM a better fit than 2.54 mm pitch headers?
A 2 mm pitch reduces the total connector length for a 10-position header to 0.787 inch versus approximately 0.984 inch for a 2.54 mm pitch version, saving about 5 mm of PCB width. This compactness benefits SBC expansion boards, sensor breakout modules, and RF evaluation boards where connector footprint reduction matters.
What contact finish does TMM-110-01-T-S-SM use, and how does that affect mating connector selection?
The TMM-110-01-T-S-SM uses matte tin (Sn) over nickel (Ni) on both mating and termination contacts. Mating connectors should also be tin or tin-compatible to avoid galvanic incompatibility. Tin contact systems are reliable across -55°C to +125°C operating ranges and support multiple hundred mating cycles under typical signal connector loads.
