What are the key features of TSM-123-02-SM-SH-A?
- Dual-row 23-position layout at 0.100 inch pitch delivers 46 contacts in a surface-mount horizontal footprint, maximizing signal density without increasing connector height
- Single-row horizontal (SH) orientation enables right-angle cable-to-board connections at PCB edges, minimizing stack height in enclosure-constrained assemblies
- Surface-mount (SM) termination style supports automated SMT reflow assembly, ensuring consistent solder joint quality across all 46 contact positions in high-volume production
What is TSM-123-02-SM-SH-A used for?
The TSM-123-02-SM-SH-A is used in industrial control panels, embedded computing modules, and communication equipment where a right-angle, surface-mount 46-contact interface is required at the PCB edge. Its horizontal orientation makes it ideal for front-panel or backplane connector interfaces where cables or mating boards approach from the side rather than perpendicular to the PCB surface. The 0.100 inch pitch dual-row layout is compatible with a wide range of standard ribbon cables and mating socket connectors, simplifying system integration.

Frequently Asked Questions
How does the single-row horizontal (SH) orientation of the TSM-123-02-SM-SH-A reduce enclosure height in right-angle connector designs?
The single-row horizontal orientation positions the 46 contacts so the mating direction is parallel to the PCB surface rather than perpendicular to it. This allows cable or mating board connections to exit toward the PCB edge, reducing the vertical profile above the board by eliminating the need for a tall vertical header. In enclosures where the internal height clearance is under 15 mm, this right-angle configuration is often the only viable 0.100 inch pitch, 46-contact SMT option.
What assembly advantages does the surface-mount (SM) termination of the TSM-123-02-SM-SH-A offer compared to through-hole terminal strips?
Surface-mount termination allows the TSM-123-02-SM-SH-A to be placed and reflowed alongside other SMT components in a single pass, eliminating the separate wave soldering or hand-soldering step required for through-hole connectors. This reduces assembly cycle time and cost at volumes exceeding 500 units per run, and the 0.100 inch pitch SMT footprint can be inspected and reworked with standard automated optical inspection (AOI) equipment after reflow.
For a 46-signal edge interface on a 100 mm x 80 mm embedded module, when is the TSM-123-02-SM-SH-A a better fit than a 0.050 inch pitch dual-row right-angle connector?
The TSM-123-02-SM-SH-A at 0.100 inch pitch is preferred when the ribbon cable or mating connector is a standard 0.100 inch pitch type, since this eliminates the need for custom or fine-pitch cables that are more costly and harder to source. The 0.100 inch pitch also provides stronger individual solder joints, making the connector more resistant to mechanical stress from repeated cable mating at the PCB edge compared to a 0.050 inch pitch alternative with finer, more fragile solder connections.
