Key Features
- 62 total positions in a dual-row 0.100" (2.54 mm) pitch layout for high signal density
- Stand-off low-profile (STL) mounting provides controlled board clearance for component access
- Gold-plated contacts for superior corrosion resistance and reliable low-resistance connection
- Tape-and-reel (TR) packaging supports fully automated pick-and-place SMT assembly
- Dual-row design with 31 positions per row minimizes PCB footprint length
- Surface mount termination compatible with standard reflow soldering at up to 260°C
Applications
The TSM-131-04-STL-DH-A-K-TR is used in high-density module-to-baseboard and board-to-board interconnect designs requiring 62 signal positions on a 0.100" pitch with a stand-off low-profile mounting that maintains a defined clearance gap between PCBs. It is commonly specified in embedded computing platforms, industrial signal conditioning modules, and rugged electronics where component access beneath the connector is needed and a large number of signal connections must be made through a single compact SMT interface.

Frequently Asked Questions
What does the STL suffix mean in TSM-131-04-STL-DH-A-K-TR, and how does it differ from standard low-profile or high-profile TSM variants?
The STL suffix denotes a stand-off low-profile mounting style, which incorporates a molded standoff to set a defined gap of approximately 1.0 mm between the connector body and the PCB surface while keeping the overall above-board height lower than standard high-profile variants. This gap allows flux cleaning and visual inspection beneath the 62-position connector body after reflow, which is critical in high-reliability industrial and defense assemblies.
How many positions does the TSM-131-04-STL-DH-A-K-TR provide, and how are they distributed in the dual-row arrangement?
The TSM-131-04-STL-DH-A-K-TR provides 62 total positions with 31 contacts in each of its 2 rows, spaced on a 0.100" (2.54 mm) pitch. Routing 62 signals through a single connector reduces the number of individual connection points on the PCB and concentrates 62 pins into a connector body roughly 3.1 inches long, compared to separate connectors that would consume more board perimeter.
For a high-mix, high-volume SMT production line, what packaging and assembly advantages does the TSM-131-04-STL-DH-A-K-TR offer?
The TR suffix specifies tape-and-reel packaging, delivering the 62-position SMT terminal strip on a standard reel for direct feeder loading into pick-and-place equipment. The surface mount termination style eliminates through-hole drilling and enables placement alongside other SMD components in a single reflow pass, reducing assembly cycle time compared to mixed SMT/through-hole connector designs.
In modular embedded computing designs, when is the 62-position TSM-131-04-STL-DH-A-K-TR preferred over a lower pin count TSM variant?
The 62-position TSM-131-04-STL-DH-A-K-TR is preferred when the system interface requires more than 52 to 54 signal lines, for example when routing multiple SPI, UART, GPIO, power, and ground rails from a processor module to a carrier board in a single connector spanning 31 pins per row. Designs requiring fewer than 50 pins can use a shorter TSM variant such as TSM-125 or TSM-126, but adding 62 positions in one connector reduces connector-to-connector spacing and simplifies PCB layout.
