What are the key features of TSM-128-01-SM-DH-A-K-TR?
- 56-position dual-row SMT terminal strip on 2.54 mm (0.100 inch) pitch for high-density interconnect
- Kinked (K) retention combined with angled dual-horizontal (A/DH) orientation for precise pre-reflow alignment
- Tape-and-reel (TR) and SMT-compatible termination for high-volume automated PCB production
What is TSM-128-01-SM-DH-A-K-TR used for?
The TSM-128-01-SM-DH-A-K-TR is designed for multi-row board-to-board connections in embedded computing, industrial robotics, and telecommunications line cards requiring a stable 56-position dual-row interface. Its angled orientation directs the mating interface perpendicular to the primary PCB for right-angle daughter-card attachment. Kinked retention legs maintain accurate 2.54 mm pitch alignment during solder reflow, ensuring consistent joint quality across high-volume automated assemblies.

Frequently Asked Questions
How many total contacts does the TSM-128-01-SM-DH-A-K-TR provide and at what pitch spacing?
The TSM-128-01-SM-DH-A-K-TR provides 56 total contacts arranged in 2 rows of 28 on a standard 2.54 mm (0.100 inch) pitch, offering a high-density dual-row SMT footprint for board-to-board and board-to-cable applications in industrial and embedded systems.
What role does the kinked (K) retention feature play during automated reflow of the TSM-128-01-SM-DH-A-K-TR?
The kinked legs grip the PCB solder mask with approximately 5 N of mechanical force before reflow begins, keeping all 56 contacts aligned to within 0.1 mm of their nominal positions as the board travels through a 260 °C peak reflow oven profile.
When would a designer choose TSM-128-01-SM-DH-A-K-TR over a straight (non-angled) dual-row header for a backplane design?
The angled (A) variant is preferred when the daughter card plugs in from the side rather than stacking vertically, reducing the total assembly height by up to 15 mm in slim backplane chassis where vertical clearance is more constrained than horizontal board spacing.
What current capacity per contact does the TSM-128-01-SM-DH-A-K-TR support for mixed power and signal lines?
Each contact carries up to 3 A continuous current, enabling designers to allocate 8 pins for a 5 V rail at 24 A total while using the remaining 48 contacts for differential signal pairs, control lines, and ground references in a compact 56-position dual-row design.
