What are the key features of TSM-124-02-S-DH-A-K-TR?
- 48-position dual-row 2.54 mm pitch SMT terminal strip with shrouded housing for guided mating and robust connector alignment
- Single-post (S) termination style reduces PCB land area versus square-post variants while maintaining reliable electrical contact
- Tape-and-reel (TR) packaging enables automated pick-and-place for high-volume PCB assembly
- Dual-height (DH) construction accommodates different mating connector heights for design flexibility in stacked board assemblies
What is TSM-124-02-S-DH-A-K-TR used for?
TSM-124-02-S-DH-A-K-TR is used in dual-row shrouded board-to-board and board-to-cable interconnection in industrial automation, embedded control systems, and signal routing panels where 48 signal or power pins are needed at the standard 2.54 mm pitch. The shrouded housing and tape-and-reel packaging make it especially suitable for high-volume production of rack-mount equipment and embedded computing baseplates that require polarized guided mating.

Frequently Asked Questions
What distinguishes TSM-124-02-S-DH-A-K-TR from the TSM-124-02-F-DH-A-K-TR variant?
TSM-124-02-S-DH-A-K-TR uses a single-post (S) pin style, which has a smaller PCB land requirement than the square-post (F) style in TSM-124-02-F-DH-A-K-TR. Both offer 48 positions at 2.54 mm pitch in tape-and-reel, but the S variant suits designs where land area is constrained on the 0.100 inch grid.
How does the shrouded dual-row housing of TSM-124-02-S-DH-A-K-TR prevent mating errors?
The shrouded housing of TSM-124-02-S-DH-A-K-TR incorporates polarizing keys and a surrounding wall around all 48 positions in the 2.54 mm dual-row array, ensuring the mating connector can only be inserted in the correct orientation, preventing misalignment damage during field assembly or repeated plug-and-unplug operations.
For what industrial PCB designs is a 48-pin 2.54 mm SMT terminal strip like TSM-124-02-S-DH-A-K-TR preferred over a board-to-board socket?
Industrial control backplanes, PLC I/O modules, and relay driver boards prefer a 48-pin 2.54 mm SMT terminal strip like TSM-124-02-S-DH-A-K-TR because the standard 0.100 inch pitch is compatible with mass-termination cable connectors and breadboard prototyping, and the SMT footprint reduces BOM cost compared to through-hole socket alternatives while supporting reflow temperatures up to 260°C.
