What are the key features of TSM-135-04-LM-DH-A-P-TR?
- 70-position dual-row surface mount terminal strip with 0.100-inch (2.54 mm) pitch offering 35 contacts per row for high pin-count connectivity
- Low-mount (LM) height profile reducing connector standoff height for slim PCB stack assemblies and space-constrained enclosures
- Tape-and-reel (TR) packaging enabling seamless integration into automated high-volume SMT pick-and-place production lines
- Gold-plated contact finish providing low contact resistance and reliable signal integrity across the full 70-position interconnect
What is TSM-135-04-LM-DH-A-P-TR used for?
The TSM-135-04-LM-DH-A-P-TR is suited for high pin-count board-to-board and wire-to-board connections in embedded computing platforms, industrial automation controllers, and communication modules where 70 positions in a 0.100-inch pitch format are required. Its low-mount design makes it ideal for slim PCB stack assemblies in rack-mount instruments and portable test equipment. The tape-and-reel packaging supports high-volume production environments where automated placement of 70-position connectors is critical for throughput and placement accuracy.

Frequently Asked Questions
How does the low-mount (LM) designation affect the installed height of TSM-135-04-LM-DH-A-P-TR on a PCB?
The low-mount (LM) variant of TSM-135-04-LM-DH-A-P-TR reduces the above-board connector height compared to standard TSM profile variants, typically by 1 mm to 2 mm. This lower profile is critical in slim enclosures or stacked PCB assemblies where a standard-height 70-position connector at 0.100-inch pitch would violate the board-to-board clearance requirement.
Why does the tape-and-reel (TR) packaging matter for TSM-135-04-LM-DH-A-P-TR in a production environment?
Tape-and-reel packaging on TSM-135-04-LM-DH-A-P-TR allows placement by automated pick-and-place machines at production rates exceeding 1000 components per hour, versus manually placing loose connectors at a fraction of that speed. For 70-position SMT connectors in production quantities above 500 units, tape-and-reel dramatically reduces placement cycle time and mis-placement defect rates.
What mating connector from SAMTEC pairs with TSM-135-04-LM-DH-A-P-TR for a dual-row 0.100-inch board stacking assembly?
The TSM-135-04-LM-DH-A-P-TR mates with SAMTEC's SFM or SSM series socket strips at 0.100-inch pitch with 70 positions, providing dual-row board-to-board stacking at customizable stack heights from approximately 4 mm to 20 mm. The dual-row (DH) configuration on the TSM engages the corresponding female socket rows simultaneously, ensuring all 70 positions make contact with uniform insertion force.
For a 70-position parallel bus interface on an industrial controller PCB, how does TSM-135-04-LM-DH-A-P-TR compare to using multiple smaller connectors?
Using a single TSM-135-04-LM-DH-A-P-TR for 70 positions rather than five 14-position or two 35-position connectors reduces total PCB real estate by eliminating inter-connector gaps and reduces assembly time from multiple separate placements to one. A single 70-position dual-row connector at 0.100-inch pitch occupies approximately 35 mm x 5 mm, while 5 separate connectors would require spacing gaps adding 10 mm or more of additional board length.
