What are the key features of TSM-125-04-T-DH-A-K-TR?
- 50-position dual-row terminal strip at 0.100 inch (2.54 mm) standard pitch for high-density SMT signal routing on industry-standard PCB grids
- Top-entry (T) dual-height (DH) profile supports vertical mating orientation for compact PCB stacking and module-on-board designs
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly with consistent placement accuracy for high-volume production
What is TSM-125-04-T-DH-A-K-TR used for?
The TSM-125-04-T-DH-A-K-TR is suited for high-density board-to-board signal interconnect in FPGA mezzanine cards, embedded computing modules, and industrial backplane systems requiring 50 contacts at the standard 0.100 inch pitch. Its top-entry dual-height orientation supports vertical PCB stacking designs where mating boards align perpendicular to the base board surface. The tape-and-reel format makes it production-ready for automated SMT assembly lines handling large-volume orders.

Frequently Asked Questions
What is the pin count and pitch of the TSM-125-04-T-DH-A-K-TR terminal strip?
The TSM-125-04-T-DH-A-K-TR provides 50 positions arranged in a dual-row configuration at a 0.100 inch (2.54 mm) standard pitch, totaling 25 contacts per row. This widely adopted pitch ensures compatibility with a broad range of mating connectors and standard PCB footprints in embedded computing and industrial applications.
How does the top-entry dual-height design of TSM-125-04-T-DH-A-K-TR differ from horizontal variants?
The top-entry (T) orientation means mating connectors insert vertically from above, as opposed to horizontal side-entry variants. The dual-height (DH) body accommodates two board heights above the PCB surface, making it suitable for stacked board assemblies where 2 boards must connect at specific vertical offsets, such as mezzanine daughter cards sitting at a fixed 8 mm or 12 mm height above a base board.
What manufacturing advantages does the TR packaging provide for TSM-125-04-T-DH-A-K-TR?
Tape-and-reel (TR) packaging supplies the 50-position terminal strips pre-loaded on a reel suitable for automated SMT pick-and-place machines, which dramatically improves throughput and reduces placement errors in high-volume PCB assembly. For boards requiring multiple connectors, reel packaging also reduces per-unit handling time compared to tray or tube formats during large production runs.
Is TSM-125-04-T-DH-A-K-TR a suitable replacement for a lower-count SAMTEC terminal strip on a parallel bus design?
Yes, for parallel bus interfaces or GPIO headers that require 40 or more signals, consolidating into a single TSM-125-04-T-DH-A-K-TR with 50 positions at 0.100 inch pitch is more efficient than using two separate 25-position connectors. This reduces the number of solder joints by up to 50%, lowers the board component count, and simplifies mechanical alignment between mating boards in the stack.
