What are the key features of TSM-124-02-T-DH-A-K-TR?
- 48 pins in a dual-row 2.54 mm pitch SMT strip, combining standard 0.100 inch spacing with surface-mount processability
- DH (dual height) tail-down design enables simultaneous top-side SMT reflow and bottom-side mating connector engagement
- Tape-and-reel (TR) packaging on 8 mm carrier tape for automated pick-and-place at high-volume production rates
What is TSM-124-02-T-DH-A-K-TR used for?
The TSM-124-02-T-DH-A-K-TR is used in test and measurement boards, embedded controller modules, and evaluation platforms requiring 48-pin board-to-board signal routing at 2.54 mm pitch. Its dual-row layout provides a high pin density in a short strip length, suitable for connecting processor daughter cards, FPGA breakout boards, and peripheral interface modules. The tail-down design also enables right-angle board stacking in enclosure-constrained industrial products.

Frequently Asked Questions
How many positions and what pitch does the TSM-124-02-T-DH-A-K-TR connector provide?
The TSM-124-02-T-DH-A-K-TR provides 48 positions arranged in a dual-row configuration with 2.54 mm (0.100 inch) pin pitch. This 48-pin count is sufficient to carry 16 data lines plus address, control, and power signals in parallel bus interconnects typical of embedded microcontroller and FPGA development boards.
What does the DH designation mean for TSM-124-02-T-DH-A-K-TR and how does it influence board stack-up design?
DH stands for dual height, indicating the connector has tail pins that extend through the PCB and a surface-mount body that reflows to the top side. This construction allows a mating plug connector to engage from below the board, creating a board-to-board stack height determined by the DH tail length, typically 3 mm to 6 mm, making it suitable for tight 10 mm or less stack-up assemblies.
Can TSM-124-02-T-DH-A-K-TR be processed through standard reflow soldering without manual assembly steps?
Yes, the SMT body of TSM-124-02-T-DH-A-K-TR is designed for paste-and-reflow processing in standard reflow ovens at peak temperatures up to 260°C per IPC/JEDEC J-STD-020. The TR suffix confirms tape-and-reel delivery compatible with automated pick-and-place machines, eliminating manual placement of the 48-pin connector during SMT line production.
Which Samtec mating connector series is compatible with TSM-124-02-T-DH-A-K-TR?
The TSM series mates with Samtec SSM (single-row socket) and SSW (square post socket) connectors at 2.54 mm pitch, as well as standard 0.100 inch dual-row socket housings from compatible families. Designers should verify the mated stack height against the DH tail dimension, typically requiring a socket with 3 mm to 8 mm of engagement depth to achieve reliable 48-pin electrical contact across the connector interface.
