What are the key features of TSM-124-03-LM-SH-A?
- 24-position dual-row 0.100" (2.54 mm) pitch SMT terminal strip in single-row horizontal (SH) orientation for low-profile PCB edge connections
- LM (low mounting) contact style minimizes component height above PCB, ideal for space-constrained and low-profile electronic assemblies
- A-suffix additional plating option enhances gold contact surface treatment for improved corrosion resistance and extended mating cycle reliability
What is TSM-124-03-LM-SH-A used for?
The TSM-124-03-LM-SH-A is designed for horizontal PCB edge interconnects in panel-mount assemblies, backplane connections, and rack-mount electronics where low component height is essential. Its 24-position dual-row layout at 0.100-inch pitch supports standard-density signal and power routing in industrial controllers and embedded systems. The SMT horizontal configuration enables automated assembly and simplified cable routing in modular electronic equipment.

Frequently Asked Questions
What does the SH suffix mean in TSM-124-03-LM-SH-A and how does it affect PCB layout?
The SH suffix in TSM-124-03-LM-SH-A designates a single-row horizontal mounting orientation, meaning the 24 contacts extend horizontally along the PCB edge rather than vertically. This configuration reduces component height above the board surface and enables right-angle mating with cables or adjacent boards in panel-mount and backplane assemblies at 0.100-inch pitch.
How many contacts and rows does the TSM-124-03-LM-SH-A provide in its dual-row configuration?
The TSM-124-03-LM-SH-A provides 24 total positions in a dual-row arrangement at 0.100 inch (2.54 mm) pitch, with 12 contacts per row. This configuration supports simultaneous routing of up to 24 signals or a combination of signal and power lines in compact PCB-edge connector applications for industrial and embedded systems.
For which PCB assembly methods is the TSM-124-03-LM-SH-A compatible?
The TSM-124-03-LM-SH-A is an SMT (surface mount technology) connector compatible with automated pick-and-place and standard reflow soldering processes, including lead-free profiles at up to 260°C peak temperature. This enables high-throughput PCB manufacturing for industrial controllers, communications equipment, and test fixtures requiring 24-position horizontal edge connectors at 0.100-inch pitch.
When is TSM-124-03-LM-SH-A a better choice than a vertical through-hole terminal strip for backplane designs?
The TSM-124-03-LM-SH-A is preferable over vertical through-hole terminal strips in backplane designs where board thickness constraints or component clearance below the PCB prevent through-hole mounting. The SMT horizontal low-mount design eliminates through-hole drilling and wave soldering steps, saving process time while maintaining 24-contact connectivity at 0.100-inch pitch for backplane daughter card interfaces.
