Key Features
- 50-position dual-row layout at 0.100 inch (2.54 mm) pitch enables high-density SMT signal interconnect on standard grid PCBs
- Horizontal (H) dual-height (DH) configuration suits low-profile PCB stacking and board-to-board mating in constrained enclosures
- Tape-and-reel (TR) packaging supports automated high-volume SMT pick-and-place assembly for consistent placement accuracy
Applications
The TSM-125-04-H-DH-A-K-TR is designed for high-density board-to-board signal interconnect in embedded computing, communication modules, and industrial control backplanes requiring 50 contacts at a 0.100 inch pitch. Its horizontal dual-height profile allows compact PCB stacking in server blades, FPGA development boards, and test fixture designs. The tape-and-reel packaging facilitates efficient automated assembly in high-volume production environments.

Frequently Asked Questions
How many positions does the TSM-125-04-H-DH-A-K-TR support and at what pitch?
The TSM-125-04-H-DH-A-K-TR supports 50 positions arranged in a dual-row configuration at a standard 0.100 inch (2.54 mm) pitch. This matches the most common PCB grid spacing, allowing direct compatibility with a wide range of mating connectors and industry-standard footprints without special layout requirements.
What does the tape-and-reel packaging mean for manufacturing with the TSM-125-04-H-DH-A-K-TR?
The TR suffix indicates tape-and-reel packaging, which means these 50-position connectors are supplied on a reel ready for automated SMT pick-and-place machines. This format reduces manual handling errors and supports high-volume PCB assembly lines that require consistent 0.100 inch pitch placement across batches of boards.
Which PCB design scenarios benefit most from the dual-height horizontal orientation of TSM-125-04-H-DH-A-K-TR?
The horizontal dual-height (DH) profile is ideal for PCB stacking applications such as FPGA mezzanine cards, server blade add-in boards, and embedded computing modules where mating boards must align at specific height offsets. With 50 positions providing wide signal bandwidth across 2 rows, it suits designs that route 25 differential pairs or mixed signal and power lines between stacked boards.
When should engineers consider TSM-125-04-H-DH-A-K-TR over a lower position-count SAMTEC terminal strip?
Engineers should select the 50-position TSM-125-04-H-DH-A-K-TR when designs require routing more than 25 signals per connector between boards at the standard 0.100 inch pitch, such as in parallel bus interfaces, GPIO expansion headers, or high-channel-count DAQ boards. Opting for a single 50-position connector instead of two 25-position strips also reduces the number of solder joints and board assembly steps.
