Key Features
- 70-position dual-row layout at 0.100" (2.54 mm) pitch delivering high signal capacity in a single SMT connector
- Double-height (DH) vertical configuration accommodating taller mating headers for extended board-to-board stacking clearance
- Tape-and-reel (TR) packaging enabling automated pick-and-place assembly in high-volume PCB production
- Gold-plated contacts providing reliable, low-resistance electrical connections across multiple mating cycles
Applications
The TSM-135-02-T-DH-A-P-TR is suited for backplane and mezzanine board applications requiring 70 signal connections at the standard 0.100" pitch via surface-mount termination. It is used in industrial automation controllers, embedded computing expansion boards, and test and measurement instrumentation where a single high-position-count SMT terminal strip simplifies wiring and reduces connector count. The double-height design accommodates larger mating connectors in board-stack configurations with taller clearance requirements.

Frequently Asked Questions
How many positions does the TSM-135-02-T-DH-A-P-TR provide, and what pitch does it use?
The TSM-135-02-T-DH-A-P-TR provides 70 contact positions at the industry-standard 0.100" (2.54 mm) pitch in a dual-row, double-height vertical surface-mount configuration. The 70-position count allows engineers to consolidate a large number of signal, power, and ground connections onto a single SMT connector, reducing PCB complexity and assembly steps.
What does the double-height (DH) designation mean for the TSM-135-02-T-DH-A-P-TR in a stacked board design?
The DH (double-height) designation indicates that the TSM-135-02-T-DH-A-P-TR has a taller insulator body than standard-height TSM variants at the same 2.54 mm pitch. This additional height provides increased board-to-board clearance in stacking configurations, accommodating components mounted close to the connector on either board and allowing for taller mating headers without mechanical interference.
Which systems benefit most from the 70-position layout of the TSM-135-02-T-DH-A-P-TR?
Industrial PLC backplanes, embedded computing carrier boards, and multi-function I/O expansion modules benefit most from the 70-position, 2.54 mm pitch layout of the TSM-135-02-T-DH-A-P-TR. The high contact count allows a single connector to carry data buses up to 32 bits wide, multiple power and ground returns, and control signals simultaneously, simplifying PCB routing and reducing the number of discrete connectors in complex systems.
How does tape-and-reel packaging influence the sourcing and assembly of the TSM-135-02-T-DH-A-P-TR?
Tape-and-reel packaging makes the TSM-135-02-T-DH-A-P-TR directly compatible with automated SMT pick-and-place equipment, reducing placement cycle time for this 70-position, 2.54 mm pitch connector on high-volume production lines. Procurement teams can order reel quantities from authorized SAMTEC distributors, simplifying inventory management and ensuring consistent component orientation during assembly compared to bulk-packaged alternatives.
