What are the key features of TSM-135-04-LM-SH-A?
- 35-position dual-row SMT terminal strip with 2.54 mm pitch and single-row horizontal orientation for low-profile board-stacking applications
- LM (Low-profile Male) contact style minimizes connector height above the PCB surface, enabling thinner product form factors in portable or stacked-board designs
- Surface mount single-row horizontal configuration allows side-by-side daughter-card attachment without vertical stack height penalty
What is TSM-135-04-LM-SH-A used for?
The TSM-135-04-LM-SH-A suits low-clearance daughter-card and mezzanine interconnect designs in embedded computing, telecommunications, and instrumentation where a 35-position horizontal SMT connector is needed within tight height budgets. Its 2.54 mm pitch and horizontal single-row footprint simplify PCB routing while supporting reliable multi-signal board-to-board connections.

Frequently Asked Questions
What makes the SH (single-row horizontal) orientation of TSM-135-04-LM-SH-A advantageous for mezzanine card designs?
The single-row horizontal (SH) orientation allows the TSM-135-04-LM-SH-A to mate with a daughter card that lies horizontally alongside the main board rather than stacking vertically, keeping the total assembly height below typical vertical stacking designs by 5 mm or more. This is critical in 1U rackmount enclosures and thin industrial panels with less than 20 mm of available vertical clearance.
How many signals does the TSM-135-04-LM-SH-A support, and how does the dual-row layout help with routing?
The TSM-135-04-LM-SH-A carries 35 positions across its dual-row layout on a 2.54 mm pitch, allowing dense signal aggregation in a footprint roughly 44.45 mm long. Dual-row routing reduces the total connector edge length versus a single-row equivalent, simplifying PCB trace routing from processor, FPGA, or sensor interfaces in compact embedded boards.
When selecting between TSM-135-04-LM-SH-A and a standard vertical SMT strip, which board-height constraint drives the decision?
Engineers choose the TSM-135-04-LM-SH-A horizontal variant when the board-to-board vertical gap is less than 10 mm, making a vertical mating orientation impractical. The LM low-profile contact style further reduces above-board height to under 3 mm, making it the preferred choice for thin-form-factor tablets, embedded compute modules, and test fixtures with strict Z-axis constraints.
