What are the key features of TSM-112-02-S-DH-A-K-TR?
- 24 positions in dual-row 2.54 mm pitch SMT layout balances pin density and board real estate efficiently
- Friction-lock keying (K) prevents mis-insertion in multi-connector assemblies on industrial and embedded boards
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place for cost-effective high-volume production
What is TSM-112-02-S-DH-A-K-TR used for?
The TSM-112-02-S-DH-A-K-TR is suited for embedded computing modules, industrial I/O expansion cards, and communication interface boards requiring a 24-pin, 2.54 mm pitch SMT connector. Its dual-row design accommodates signal, power, and ground contacts within a compact footprint, and the keying feature prevents assembly errors in densely populated boards. The tape-and-reel format integrates seamlessly into automated SMT manufacturing lines.

Frequently Asked Questions
How many positions and rows does TSM-112-02-S-DH-A-K-TR have, and what is the contact pitch?
The TSM-112-02-S-DH-A-K-TR has 24 total positions arranged in 2 rows of 12 contacts on a 2.54 mm (0.100 inch) pitch. Each contact is rated at 3 A, enabling the connector to carry both low-level signals and modest power rails simultaneously on the same 24-pin interface.
What does the S contact option mean on TSM-112-02-S-DH-A-K-TR compared to other contact options?
The S suffix denotes a solder-tail contact termination style, where the contact pins are soldered directly to SMT pads on the PCB. This differs from press-fit (PF) or through-hole variants, as the solder joint forms during standard reflow at peak temperatures around 260°C, providing reliable 24-contact electrical and mechanical attachment without additional tooling.
How does friction-lock keying on TSM-112-02-S-DH-A-K-TR reduce assembly errors in multi-connector boards?
The K keying option incorporates a physical polarization feature in the insulator housing that prevents engagement with non-keyed or differently-keyed mating headers. On boards with several 24-pin connectors in close proximity, such as multi-channel motor drives or backplane expansion slots, keying eliminates the risk of swapping connectors, protecting 3.3 V, 5 V, or 12 V circuits from reverse connection damage.
Which mating headers are compatible with TSM-112-02-S-DH-A-K-TR for board-stacking applications?
SAMTEC TSW-112 and SSW-112 series 24-pin dual-row headers on 2.54 mm pitch are the standard mating options for TSM-112 connectors. Stacking heights from approximately 8.5 mm to 20 mm are achievable by selecting the appropriate mating header, allowing flexible board-to-board separation in compact embedded modules, SBCs, and industrial expansion frames.
