Key Features
- 68-position dual-row surface mount terminal strip with 2.54 mm (0.100") pitch
- Tall (T) housing variant providing additional mating depth for secure retention with counterpart connectors
- Dual-height (DH) construction accommodating daughter cards at varied standoff heights
- Keying (K) feature blocking incorrect connector orientation across all 68 positions
- Tape and reel (TR) packaging for high-volume automated pick-and-place SMT assembly
Applications
The TSM-134-01-T-DH-A-K-TR is designed for reliable signal distribution in embedded computing backplanes, industrial I/O modules, and telecommunications equipment where 68 positions at 2.54 mm pitch are needed in a surface mount form factor. Its tall dual-height housing with keying ensures proper mating alignment and prevents assembly errors in high-density PCB layouts used in data acquisition systems, PLC expansion cards, and modular industrial controllers.

Frequently Asked Questions
How does the T (tall) housing on TSM-134-01-T-DH-A-K-TR improve mating reliability versus standard-height TSM connectors?
The T tall housing increases the mating engagement depth compared to standard TSM profile variants, providing greater mechanical retention force across all 68 positions at 2.54 mm pitch. This deeper mating reduces the risk of partial or intermittent contact in applications subject to vibration, board flex, or thermal expansion in industrial and embedded electronics environments.
What PCB routing challenges should engineers anticipate when placing a 68-position 2.54 mm pitch dual-row SMT connector?
At 2.54 mm pitch across 68 positions in a dual-row arrangement, the connector footprint spans approximately 44 mm in row length. Designers must plan via escape routing for 68 signals, typically using dogleg or fan-out patterns with 0.8 mm design rules to clear the connector outline, while maintaining adequate solder mask clearance on both rows of pads for reliable reflow at 260°C peak temperature.
When does the A suffix on TSM-134-01-T-DH-A-K-TR indicate a different termination or assembly option from non-A variants?
The A suffix in SAMTEC TSM part numbers typically denotes an alternate termination or solder tail configuration, such as a longer or shorter solder tail length compared to the standard variant. For the 68-position TSM-134-01-T-DH-A-K-TR, this can affect solder joint depth and paste volume requirements during SMT reflow, important for achieving reliable solder fillets on all 68 positions in automated assembly.
