What are the key features of TSM-135-01-TL-DH-A-K-TR?
- 70 positions in dual-row (DH) configuration at 0.100" (2.54 mm) pitch for maximum signal density
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for high-volume production
- Low-profile (TL) surface-mount design minimizes connector height above the PCB
- -K tin contact finish provides RoHS compliant, lead-free termination
- Dual-row layout provides 35 pins per row for efficient backplane and daughtercard connections
What is TSM-135-01-TL-DH-A-K-TR used for?
The TSM-135-01-TL-DH-A-K-TR is used in high-density board-to-board interconnect assemblies such as backplanes, memory expansion modules, and industrial controller daughtercards requiring 70 or more signal paths. Its low-profile SMT form factor and tape-and-reel availability make it suitable for automated production lines in telecommunications, server hardware, and test and measurement equipment.

Frequently Asked Questions
How many signal positions does the TSM-135-01-TL-DH-A-K-TR provide and what is the pin pitch?
The TSM-135-01-TL-DH-A-K-TR offers 70 total positions arranged in 2 rows of 35 pins each, with a standard 0.100" (2.54 mm) center-to-center pitch. This density supports routing up to 70 independent signals on a single connector, which is common in backplane interconnect and memory module applications.
What does the low-profile (TL) designation mean for PCB stack-up constraints in this SAMTEC terminal strip?
The TL (low-profile) suffix indicates a reduced connector body height above the PCB surface, typically less than 4 mm, compared to standard-height TSM variants. This allows engineers to design tighter board-to-board stack heights in blade servers, compact industrial controllers, or multi-board enclosures where vertical space constraints are as tight as 8 mm between adjacent boards.
How does the -K tin contact finish on the TSM-135-01-TL-DH-A-K-TR affect soldering and RoHS compliance?
The -K suffix specifies a tin (Sn) contact finish, which is fully RoHS compliant and lead-free. Tin-finished contacts are compatible with standard Sn-Ag-Cu (SAC) solder alloys used in reflow processes at peak temperatures up to 260°C, making the TSM-135-01-TL-DH-A-K-TR a straightforward drop-in for compliant SMT assembly lines.
For a 70-position dual-row connector, what procurement quantities are typically available on tape-and-reel reels?
SAMTEC TSM series connectors in tape-and-reel format are typically available in reel quantities of 500 to 1000 pieces per reel, depending on the specific part length. Procurement teams planning builds of fewer than 500 units should confirm whether cut-tape options are offered by distributors, as minimum order quantities and per-unit pricing can differ significantly between full-reel and cut-tape purchases at quantities below 100 pieces.
