What are the key features of TSM-122-04-TL-DH-A-K-TR?
- 44 pins at 2.54 mm pitch in a surface-mount tail-left (TL) DH orientation enabling right-angle or offset board-to-board mating
- Dual-height (DH) design with tail pins extending through-board for engagement from below, minimizing top-side component clearance requirements
- Tape-and-reel (TR) packaging for automated SMT pick-and-place assembly compatible with standard 8 mm carrier tape systems
What is TSM-122-04-TL-DH-A-K-TR used for?
The TSM-122-04-TL-DH-A-K-TR is used in right-angle or offset board-to-board interconnects where 44 signal lines must transition between a motherboard and a perpendicular daughter card without exceeding vertical height budgets. Its tail-left orientation directs the mating interface to the left side of the PCB edge, making it suitable for stacked module assemblies in industrial control panels, embedded computing enclosures, and test fixtures with restricted access from the top. The SMT body integrates into standard reflow assembly alongside other surface-mount components.

Frequently Asked Questions
What does the TL designation mean in TSM-122-04-TL-DH-A-K-TR and how does it affect PCB layout?
TL stands for tail-left, meaning the through-board tail pins exit toward the left side of the connector body when viewed from the top. This orientation redirects the mating connector entry to the PCB edge rather than the bottom surface, which is useful when stacking boards side-by-side in a rail-mount enclosure where bottom access for a mating plug is blocked and a 44-pin side-entry interface is needed.
How many positions does TSM-122-04-TL-DH-A-K-TR have, and what signal capacity does that provide?
The TSM-122-04-TL-DH-A-K-TR provides 44 positions at 2.54 mm (0.100 inch) pitch in a single-row strip spanning approximately 110 mm. A 44-pin single-row connector can carry 32 data or GPIO lines alongside power, ground, and control signals, making it practical for interfacing microcontroller expansion boards, sensor arrays, or peripheral interface cards to a host system board.
Can TSM-122-04-TL-DH-A-K-TR withstand standard lead-free reflow soldering?
Yes, the TSM-122-04-TL-DH-A-K-TR surface-mount body is rated for lead-free reflow at peak temperatures up to 260°C per IPC/JEDEC J-STD-020. The TR tape-and-reel suffix confirms the connector ships in 8 mm carrier tape for automated pick-and-place, allowing placement in the same SMT reflow pass as other components with no manual intervention for this 44-pin connector.
Which mating socket works with TSM-122-04-TL-DH-A-K-TR for a complete board-to-board assembly?
The TSM-122 tail-left variant mates with Samtec SSM-122 single-row socket strips or standard 0.100 inch pitch female headers providing 44 positions. The DH tail length through the PCB determines the mated stack offset — verify the tail extends at least 3 mm beyond the PCB surface to develop sufficient normal contact force across all 44 pins for reliable signal continuity in the assembled interconnect.
