What are the key features of TSM-124-02-STL-SH-A?
- 24-position dual-row surface-mount terminal strip at 0.100" (2.54 mm) pitch offers 48 total contacts in an industry-standard footprint compatible with 0.100" pitch cable assemblies
- Single-row horizontal (SH) mating direction enables side-entry cable connection, reducing vertical height and facilitating front-access cable routing in panel-mount and rack-mount designs
- Tin (STL) contact finish provides cost-effective solderability and is compatible with standard lead-free reflow solder processes up to 260 °C peak temperature
What is TSM-124-02-STL-SH-A used for?
The TSM-124-02-STL-SH-A is suited for board-edge signal interconnects in industrial automation controllers, embedded computing backplanes, and test instrumentation chassis where side-entry cable access is preferred over top-entry. Its 24-position, 2.54 mm pitch layout accommodates ribbon cable assemblies carrying mixed digital I/O and power supply signals between PCB sub-assemblies. The surface-mount footprint reduces assembly cost compared to through-hole alternatives while maintaining the mechanical robustness required for panel-mount environments.

Frequently Asked Questions
What total contact count and pitch does the TSM-124-02-STL-SH-A provide in its dual-row configuration?
The TSM-124-02-STL-SH-A is a 24-position, dual-row connector at 0.100" (2.54 mm) pitch, providing 48 total contacts. This count is common in industrial backplane designs that route 32 data signals alongside 8 power, ground, and control lines through a single 0.100" pitch cable assembly to an adjacent board.
How does the single-row horizontal (SH) mating orientation of the TSM-124-02-STL-SH-A benefit enclosure designs?
The SH (single-row horizontal) mating direction allows cable assemblies to be inserted from the side of the board rather than from above, which reduces the required vertical clearance above the PCB by several millimeters. In a rack-mount enclosure with 25 mm of board-to-board vertical spacing, this can be the deciding factor that makes a 48-contact, 2.54 mm pitch connection feasible without a taller chassis.
Which soldering processes are compatible with the TSM-124-02-STL-SH-A surface-mount package?
The TSM-124-02-STL-SH-A is designed for standard SMT reflow soldering with lead-free solder paste at peak temperatures up to 260 °C. The tin (STL) contact finish provides good solderability with Sn-Ag-Cu (SAC) alloys, and the surface-mount pads for 48 contacts allow automated optical inspection (AOI) to verify joint quality after reflow.
When would a designer choose the TSM-124-02-STL-SH-A over a through-hole header for a vibration-exposed industrial PCB?
A designer may choose the TSM-124-02-STL-SH-A when the PCB must pass automated SMT assembly with reflow rather than wave soldering, or when drill holes for 48 through-hole pins at 2.54 mm pitch would compromise PCB routing density on inner layers. If vibration exceeds approximately 5 G, adding adhesive underfill or retention clips to the surface-mount body can restore the mechanical robustness of a through-hole solution.
