Key Features
- 10 positions at 0.100-inch (2.54 mm) pitch dual-row layout for versatile board interfacing
- Top-load (TL) contact design allows vertical wire or pin insertion after board mounting
- Surface-mount termination enables reflow soldering with standard SMT production equipment
- Tape-and-reel packaging optimized for automated pick-and-place in high-volume manufacturing
- Dual-height (DH) housing option accommodates various mating pin lengths and stack heights
Applications
The TSM-105-04-TL-DH-A-K-TR is used in modular PCB interconnect systems, test and measurement boards, and industrial control panels where a 10-position 0.100-inch pitch dual-row terminal strip provides reliable wire-to-board or board-to-board connectivity. Its top-load entry configuration is particularly convenient in service-accessible enclosures requiring field wire termination without desoldering the connector from the board.

Frequently Asked Questions
What does the TL designation mean, and how does it affect wire insertion in the TSM-105-04-TL-DH-A-K-TR?
The TL suffix stands for top-load, meaning wires or pins are inserted vertically from the top of the connector housing after the part is soldered to the PCB. This allows the 10-position 0.100-inch pitch terminal strip to be populated during field installation or rework without disturbing the SMT solder joints on the board.
For a 10-channel power distribution or signal interface board, what pitch and row density does this connector offer?
The TSM-105-04-TL-DH-A-K-TR provides 10 positions in a dual-row arrangement at 0.100-inch (2.54 mm) pitch, giving a total row span of approximately 0.5 inches for a compact yet accessible terminal strip suitable for power rail distribution or multi-channel analog signal interfaces in industrial and lab instrument designs.
How does the -TR tape-and-reel packaging support automated SMT assembly of this SAMTEC terminal strip?
The tape-and-reel packaging places each TSM-105-04-TL-DH-A-K-TR connector in a pocket tape on 7-inch or 13-inch reels, enabling pick-and-place machines to place 10-position dual-row connectors at automated production speeds without manual feeding, supporting high-volume builds requiring consistent SMT solder joint quality across 10 contact positions per connector.
When is a 0.100-inch pitch 10-position terminal strip a better fit than a 0.050-inch pitch alternative for the same channel count?
A 0.100-inch pitch terminal strip is preferred when wire gauge or mating pin size exceeds what a 0.050-inch pitch housing can accommodate, typically AWG 22–28 wires or standard 0.100-inch header pins. The larger 2.54 mm pitch also improves solderability during rework, lowers contact resistance for moderate current loads up to 3 A per pin, and reduces the risk of solder bridging between adjacent contacts compared to 0.050-inch alternatives.
