What are the key features of TSM-124-02-TL-DH-A-K-TR?
- 48-position dual-row SMD terminal strip on 0.100-inch (2.54mm) pitch, routing 46 signal lines plus 2 power pins through a single 58.42mm connector
- Dual-height (DH) and through-length (TL) contacts accommodate board-to-board stack heights from 6mm to 20mm without changing the host PCB footprint
- Latch (K) retention and tape-and-reel (TR) packaging combine secure mated retention with automated pick-and-place assembly for high-volume SMD production lines
What is TSM-124-02-TL-DH-A-K-TR used for?
The TSM-124-02-TL-DH-A-K-TR is designed for high-pin-count board-to-board interconnect in embedded computing backplanes, industrial PLC expansion modules, and communication blade cards where 48 signals must cross a standard 0.100-inch pitch interface. Its latch retention is particularly useful in server and rack-mount systems where vibration during shipping and operation could otherwise cause intermittent contact on a 48-pin connector. Tape-and-reel packaging supports automated SMD assembly in high-volume networking and data-center hardware manufacturing environments.

Frequently Asked Questions
How many positions does TSM-124-02-TL-DH-A-K-TR provide, and what pitch does it use for board-to-board connections?
The TSM-124-02-TL-DH-A-K-TR is a 48-position dual-row SMD terminal strip arranged as 2 rows of 24 contacts on a 0.100-inch (2.54mm) pitch, spanning a total connector length of 58.42mm. This configuration routes 46 dedicated signal lines plus 2 power or ground connections through a single industry-standard 0.100-inch footprint compatible with a wide range of SAMTEC mating headers.
What stack heights can TSM-124-02-TL-DH-A-K-TR support using its dual-height (DH) contacts?
The dual-height (DH) feature of the TSM-124-02-TL-DH-A-K-TR extends the usable contact engagement range to accommodate board-to-board stack heights from 6mm to 20mm, depending on the mating header post length selected from the SAMTEC TSM mating series. This range covers most embedded computing and industrial expansion card designs without requiring a custom PCB footprint revision when the stack height changes between product generations.
How does the latch (K) mechanism on TSM-124-02-TL-DH-A-K-TR prevent connector dropout in rack-mount systems?
The latch (K) mechanism clips the mated socket and header together, resisting pull-apart forces up to 5N to 10N and preventing connector dropout from the vibration and shock experienced during shipping or hot-swap operations in rack-mount servers. On a 48-pin connector carrying critical data bus signals, even a momentary disconnection can cause a system crash or data corruption, so the latch provides insurance beyond what contact friction alone offers.
When does a designer choose TSM-124-02-TL-DH-A-K-TR over a 0.050-inch pitch connector carrying the same 48 signals?
The TSM-124-02-TL-DH-A-K-TR on 0.100-inch pitch is preferred over a 0.050-inch pitch alternative when signal integrity at data rates below 500MHz is acceptable and hand rework capability is needed, since 0.100-inch pitch pads are large enough for a 1.5mm soldering iron tip. The 0.100-inch pitch also supports through-length (TL) posts that enable the connector to serve dual use as both a signal connector and a mechanical standoff, reducing the total component count by eliminating 2 to 4 separate PCB standoff hardware pieces.
