What are the key features of TSM-124-03-SS-DH-A-K-TR?
- 48-position dual-row SMT terminal strip at standard 0.100" (2.54mm) pitch for high pin-count board-to-board connections
- Double-height (DH) profile providing additional mating clearance for stacked PCB assemblies and mezzanine card configurations
- Tape-and-reel (-TR) packaging enabling automated pick-and-place assembly for medium and high-volume PCB production
What is TSM-124-03-SS-DH-A-K-TR used for?
The TSM-124-03-SS-DH-A-K-TR is used in board-to-board and daughtercard interconnect for embedded computing platforms, industrial automation controllers, and telecommunications equipment requiring 48 signals at 0.100" pitch. Its double-height profile accommodates stacked PCB designs where board separation of several millimeters is needed between parallel boards. This terminal strip in tape-and-reel format is also applied in instrumentation modules and expansion interface cards that require consistent dual-row 2.54mm pitch SMT connections in volume production.

Frequently Asked Questions
What position count and pitch does the TSM-124-03-SS-DH-A-K-TR offer for board-to-board connections?
The TSM-124-03-SS-DH-A-K-TR provides 48 positions in a dual-row layout at the standard 0.100" (2.54mm) pitch, with 24 pins per row. This configuration is well suited for industrial backplane-to-daughterboard and embedded computing module connections where a large number of signals must be routed reliably at a familiar 2.54mm contact spacing.
When should a PCB designer choose the double-height (DH) profile of the TSM-124-03-SS-DH-A-K-TR?
A designer should select the DH (double-height) profile when the mating connector or board assembly requires extra vertical separation between 2 stacked PCBs. The double-height standoff accommodates taller SMT or through-hole components between the boards, ensuring adequate clearance without mechanical interference in a 48-pin 0.100" (2.54mm) pitch dual-row stacked configuration.
How does the TSM-124-03-SS-DH-A-K-TR's tape-and-reel packaging support high-volume SMT production?
Tape-and-reel (-TR) packaging allows the TSM-124-03-SS-DH-A-K-TR to be fed directly into automated pick-and-place machines without manual loading, reducing handling time for 48-pin SMT connectors at 0.100" (2.54mm) pitch. This packaging format improves placement accuracy and throughput in medium-to-high volume PCB assembly environments, minimizing the risk of manual misalignment on fine-pitch pads.
Which industries most commonly use the TSM-124 series connectors in their product designs?
The TSM-124 series, including the TSM-124-03-SS-DH-A-K-TR, is commonly used in industrial automation, embedded computing, telecommunications, and test and measurement equipment. Applications requiring 48-pin dual-row board-to-board interconnect at 0.100" (2.54mm) pitch — such as I/O expansion cards, backplane interfaces, and data acquisition modules — rely on the TSM series for reliable SMT connectivity in multi-board system designs.
