What are the key features of TSM-128-03-T-DH-A-K-TR?
- 56-position dual-row terminal strip with 0.100" (2.54 mm) pitch for standard-density board interconnects
- Right-angle (A) termination enabling horizontal board-to-board mating in constrained chassis heights
- Key (K) feature preventing incorrect mating in multi-connector assemblies with 56-pin layouts
- Tape-and-reel (TR) packaging supporting automated pick-and-place SMT assembly processes
- Compatible with SAMTEC TSM series headers providing matched mating connector availability
What is TSM-128-03-T-DH-A-K-TR used for?
The TSM-128-03-T-DH-A-K-TR is used in embedded computing boards, industrial control panels, and telecommunications line cards where a 56-position right-angle dual-row SMT connector with 0.100-inch pitch is required. Its keyed configuration prevents assembly errors in multi-connector boards, and its tape-and-reel packaging makes it suitable for high-volume automated SMT production of industrial and embedded computing products.

Frequently Asked Questions
What distinguishes the TSM-128-03-T-DH-A-K-TR from the TSM-128-02-T-DH-P-TR in board interconnect design?
The TSM-128-03-T-DH-A-K-TR features a right-angle (A) termination and keyed (K) polarization, whereas the TSM-128-02-T-DH-P-TR uses a straight termination. Both are 56-position dual-row 0.100-inch pitch SMT connectors, but the right-angle variant suits designs where a horizontal mating axis is needed to reduce PCB stack height in chassis-constrained assemblies.
How does the keying feature on the TSM-128-03-T-DH-A-K-TR reduce assembly errors in multi-connector PCBs?
The key (K) feature on the TSM-128-03-T-DH-A-K-TR creates a physical polarization that prevents it from mating with non-keyed or differently keyed 56-position counterpart connectors, reducing the risk of reversed or misplaced connections in boards with multiple 0.100-inch pitch dual-row terminal strips during automated or manual assembly.
What are the procurement and packaging options available for the TSM-128-03-T-DH-A-K-TR?
The TSM-128-03-T-DH-A-K-TR is supplied in tape-and-reel (TR) format with 56 positions per connector, enabling efficient automated SMT pick-and-place assembly in high-volume production. Procurement teams should confirm reel quantities and lead times with SAMTEC authorized distributors, as right-angle keyed dual-row 0.100-inch pitch connectors may have different stocking levels than standard vertical variants.
In which end-equipment applications is the TSM-128-03-T-DH-A-K-TR most typically deployed?
This 56-position, 0.100-inch pitch right-angle dual-row SMT connector is deployed in industrial single-board computers, embedded control modules, and telecommunications cards where horizontal board mating reduces chassis height. Its 56-pin count and keyed right-angle configuration also suits data acquisition systems and backplane designs requiring polarized connections with reliable signal routing across all 56 positions.
