Frequently Asked Questions
How many positions does the TSM-124-02-LM-DH-A-K-TR provide and how are they arranged?
The TSM-124-02-LM-DH-A-K-TR provides 48 positions arranged in a dual-row configuration on a .100" (2.54 mm) pitch. This dual-row layout allows high-density connections in a compact surface mount footprint, making it suitable for board-to-board applications requiring more than 24 signals per connector.
For a high-vibration industrial design, why is the locking feature of this terminal strip important?
In high-vibration environments, unmated or partially mated connectors can cause intermittent faults. The TSM-124-02-LM-DH-A-K-TR includes a locking mechanism (K suffix) that secures the mated pair, preventing accidental disconnection. This is critical in robotics, automotive electronics, and industrial machinery where 48 signal lines must remain reliable under continuous mechanical stress.
Which production environments benefit most from the TR (tape-and-reel) packaging of this part?
Tape-and-reel (TR) packaging is designed for automated surface mount assembly lines using pick-and-place equipment. High-volume production runs, contract manufacturers, and EMS facilities benefit most, as the continuous reel format eliminates manual handling of individual parts. The TSM-124-02-LM-DH-A-K-TR in TR packaging maintains consistent orientation across thousands of placements, reducing placement errors.
How does the TSM-124-02-LM-DH-A-K-TR compare to single-row .100" terminal strips for signal density?
Compared to single-row .100" terminal strips, the dual-row TSM-124-02-LM-DH-A-K-TR doubles the signal density in the same board length. Carrying 48 positions versus 24 in a single-row equivalent, it is preferred when board real estate is limited but a large number of parallel signal or power connections—such as data buses with 32 to 48 lines—must be routed through a single connector.
