What are the key features of TSM-135-04-L-DH-A-K-TR?
- 70-position dual-row right-angle .100" (2.54 mm) pitch surface mount terminal strip for low-profile horizontal board interconnects
- Gold-plated contacts rated at 3A per pin provide corrosion-resistant, low-contact-resistance performance for signal and power applications
- Tape-and-reel (TR) delivery format enables high-speed automated pick-and-place assembly in volume PCB manufacturing
What is TSM-135-04-L-DH-A-K-TR used for?
The TSM-135-04-L-DH-A-K-TR is used in horizontally stacked computing modules, rack-mount industrial controllers, and test fixture boards where right-angle mating reduces vertical stack height. Its 70-position dual-row format provides high signal density in a compact .100" pitch footprint suitable for data acquisition and communication interface cards. The right-angle lead style is particularly valuable in enclosures with limited vertical clearance above the PCB.

Frequently Asked Questions
Why would a designer choose the right-angle variant TSM-135-04-L-DH-A-K-TR over a vertical-lead TSM-135 for the same 70-position interface?
The right-angle (L) leads on the TSM-135-04-L-DH-A-K-TR allow the mating connector to approach horizontally, reducing the PCB stack height by approximately 8 mm to 12 mm compared to a vertically-mated connector pair. This is critical in enclosures where total board stack height must remain under 20 mm, such as slim 1U rack panels or stacked processor modules.
What is the current rating per contact of the TSM-135-04-L-DH-A-K-TR and how many total contacts does it have?
The TSM-135-04-L-DH-A-K-TR has 70 total contacts across dual rows at .100" (2.54 mm) pitch, each rated at 3A. This gives the connector a combined rated capacity of 210A, enabling mixed power-and-signal usage where select pins carry up to 3A supply current while adjacent pins carry low-level digital signals.
How does the dual-row configuration of TSM-135-04-L-DH-A-K-TR reduce PCB footprint compared to a single-row 70-pin connector?
Arranging 70 contacts in 2 rows of 35 pins reduces the connector body length to approximately 88.9 mm (35 × 2.54 mm), versus 177.8 mm for a single-row design. This nearly 50% reduction in connector length frees significant PCB real estate along the board edge, benefiting high-density backplane layouts where multiple connectors share the same board edge.
Which procurement format does TSM-135-04-L-DH-A-K-TR ship in and what production volume does it suit?
The -TR suffix specifies tape-and-reel packaging, typically on 7-inch or 13-inch reels holding 500 to 1000 pieces per reel. This format suits medium-to-high volume SMT production runs and is compatible with standard pick-and-place machines with 8 mm or 12 mm tape feeders, minimizing line changeover time compared to tray or cut-tape options.
