Key Features
- 28 dual-row positions at 2.54 mm (0.100 inch) pitch providing 56 total contacts for high-count interconnects
- Low-profile STL housing reduces stacking height for height-constrained board-to-board assemblies
- Tape-and-reel (TR) format with shrouded polarized (SH-P) housing for error-free high-volume SMT placement
Applications
TSM-128-05-STL-SH-P-TR is used in embedded computing modules, industrial gateways, and data acquisition systems where a high contact count is required in a 2.54 mm pitch SMT footprint. The low-profile shrouded housing reduces the overall mated height compared to standard-height variants, enabling use in slim enclosures and stacked PCB assemblies. Tape-and-reel packaging supports uninterrupted pick-and-place production at scale.

Frequently Asked Questions
What stacking height advantage does the STL (low-profile) variant of TSM-128-05-STL-SH-P-TR offer over standard height TSM connectors?
The STL suffix on TSM-128-05-STL-SH-P-TR designates a low-profile housing that reduces the above-board height compared to standard TSM variants. This lower profile enables tighter board-to-board spacing, typically shaving 1 mm to 2 mm from the mated height, which is significant in slim enclosures where standard 5 mm housings would not clear nearby components.
With 28 dual-row positions, which signal mix is TSM-128-05-STL-SH-P-TR well suited for?
TSM-128-05-STL-SH-P-TR provides 56 total contacts across 28 dual-row positions at 2.54 mm pitch, each rated at 3 A. This mix supports simultaneous routing of multiple power rails at up to 3 A each alongside dozens of GPIO, SPI, I2C, and UART signals on a single connector, reducing the number of separate connectors needed on complex embedded processor boards.
How does the shrouded polarized (SH-P) housing on TSM-128-05-STL-SH-P-TR help in field-service scenarios?
The shrouded (SH) housing walls guide the mating header into the correct position, while the polarization peg (P) prevents 180-degree inversion. For a 56-contact connector like TSM-128-05-STL-SH-P-TR, incorrect mating could damage up to 28 signal or power lines simultaneously, so these mechanical keying features are essential when technicians replace modules in the field without detailed inspection.
