What are the key features of TSM-104-05-STL-SH-A?
- 2.54 mm (0.100 inch) pitch single-row SMT terminal strip with 4 positions for compact PCB signal breakout
- Horizontal surface-mount orientation enabling low-profile wire attachment without through-hole drilling
- Gold-plated contacts providing reliable low-resistance mating and corrosion resistance for long service life
- SAMTEC SH series shielded housing option for improved signal integrity in noise-sensitive applications
What is TSM-104-05-STL-SH-A used for?
The TSM-104-05-STL-SH-A is used for signal breakout, test access, and PCB-to-wire connections in instrumentation, robotics, and prototyping boards. Its 4-position, 2.54 mm pitch layout matches standard 0.1-inch wire harness assemblies, enabling direct connection to ribbon cables and jumper wires without additional adapters. The horizontal SMT profile suits low-clearance enclosures and slim PCB designs where vertical through-hole headers would exceed available height budgets.

Frequently Asked Questions
What pin pitch and position count does the TSM-104-05-STL-SH-A use for PCB connector layouts?
The TSM-104-05-STL-SH-A uses a 2.54 mm (0.100 inch) pin pitch with 4 positions in a single-row configuration, occupying approximately 10.2 mm of PCB length. This standard pitch is compatible with common 0.1-inch wire harnesses, ribbon cable assemblies, and jumper wires widely used in prototyping and embedded system interconnection.
For a low-profile panel-mount PCB design, how does the horizontal SMT orientation of TSM-104-05-STL-SH-A reduce assembly height?
The horizontal surface-mount orientation positions the wire entry parallel to the PCB plane rather than perpendicular, reducing the above-board height to the connector body height alone—typically under 5 mm versus 8 mm to 12 mm for vertical through-hole headers. This allows the TSM-104-05-STL-SH-A to fit inside enclosures with less than 8 mm PCB-to-lid clearance while maintaining 4-position connectivity.
How does the TSM-104-05-STL-SH-A's gold-plated contact finish affect connector reliability in intermittent-use signal ports?
Gold plating provides a minimum contact resistance below 20 mΩ and resists oxidation across temperature cycles from -55°C to +125°C, ensuring reliable signal continuity even with infrequent mating cycles. This makes the TSM-104-05-STL-SH-A suitable for test access points and diagnostic connectors that may be unplugged and re-mated dozens of times over a product's lifetime without contact degradation.
When should a design team select TSM-104-05-STL-SH-A over a through-hole terminal strip of the same pitch?
Teams should choose the SMT TSM-104-05-STL-SH-A when the PCB is fully automated through a reflow solder process with no wave soldering, or when the PCB design eliminates all through-holes to reduce cost. The SMT version also allows finer 4-layer stackup routing beneath the connector pads, and its 2.54 mm footprint remains compatible with standard 0.1-inch test probes and jumper wires used during bring-up.
