What are the key features of TSM-128-01-SS-DH-P-TR?
- 56-position single-row SMT layout at 0.100-inch pitch for linear signal buses
- Stainless-steel (SS) shell provides enhanced EMI shielding and mechanical strength
- Dual-height (DH) housing increases solder pad coverage and pull-out retention force
- Tape-and-reel (-TR) packaging for automated high-volume pick-and-place assembly
What is TSM-128-01-SS-DH-P-TR used for?
The TSM-128-01-SS-DH-P-TR is designed for grounding-sensitive or EMI-critical applications where a stainless-steel shell reduces radiated emissions at connector interfaces in instrumentation and measurement equipment. Its 56-position single-row configuration suits analog signal buses, data-acquisition front ends, and industrial I/O expansion cards that must pass conducted-emission standards. The dual-height housing also improves connector reliability in portable and field-deployable instruments exposed to mechanical shock and thermal cycling.

Frequently Asked Questions
What is the function of the stainless-steel (SS) shell on the TSM-128-01-SS-DH-P-TR compared to a plastic-only housing?
The stainless-steel shell provides structural reinforcement around the 56-position single-row connector body, significantly increasing resistance to connector warping during reflow soldering at 260°C. It also acts as an EMI shield at the board edge, reducing radiated emissions from high-speed signals switching at frequencies above 50 MHz and improving compliance with EN 55032 or FCC Part 15 radiated-emission limits.
How many total contacts does the TSM-128-01-SS-DH-P-TR provide, and what signal types can they accommodate?
The TSM-128-01-SS-DH-P-TR provides 56 contacts in a single row at 0.100-inch (2.54 mm) pitch, covering a total length of approximately 5.6 inches. The 56 positions can carry mixed signal types including 28 differential pairs for LVDS or RS-422 signals, or a combination of 40 GPIO lines, 8 analog inputs, and 8 power/ground returns on the same connector.
In which test-and-measurement scenarios does the dual-height (DH) housing of the TSM-128-01-SS-DH-P-TR add value?
Test fixtures and bench instruments that undergo frequent cable-attachment and removal cycles benefit from the dual-height (DH) housing, which increases engagement depth and solder joint area. This improves resistance to connector lifting or cold-joint fatigue under repeated 10 N plug-and-unplug forces, extending reliable service life in production test equipment and field calibration tools beyond 1,000 mating cycles.
Is the TSM-128-01-SS-DH-P-TR suitable for sourcing in production quantities, and what packaging does it use?
Yes, the -TR suffix indicates tape-and-reel packaging, enabling uninterrupted automated SMT assembly for production runs of thousands of boards. Standard reel quantities for Samtec terminal strips in this pitch are typically 250 or 500 pieces per reel, and the 56-position connector fits standard 16 mm or 24 mm carrier tape widths used by high-speed pick-and-place machines rated at 5,000 or more placements per hour.
