Frequently Asked Questions
How many positions does the TSM-126-04-L-DH-A-K-TR provide, and what pitch does it use?
The TSM-126-04-L-DH-A-K-TR provides 52 positions (26 per row) in a dual-row configuration with a standard 0.100" (2.54 mm) pitch. This industry-standard pitch ensures compatibility with a wide range of mating headers and wire-to-board housings, making it straightforward to source matching connectors from multiple vendors for cost-effective PCB interconnect designs.
What does the DH designation in TSM-126-04-L-DH-A-K-TR indicate about stack height or polarization?
The DH suffix in SAMTEC TSM nomenclature stands for dual-height, indicating that the terminal strip is designed to mate with connectors at two defined stack heights. This feature provides mechanical keying that prevents incorrect board orientation during assembly and ensures repeatable board-to-board spacing in stacked PCB configurations, typically maintaining a gap of approximately 8 mm to 11 mm between mated boards depending on the series variant.
Can TSM-126-04-L-DH-A-K-TR carry power rails alongside signal lines?
Yes. SAMTEC TSM series terminal strips are rated at approximately 1 A per contact at ambient temperature, and with 52 contacts available, multiple pins can be ganged together to carry higher current power rails. For example, tying 5 adjacent pins to a 5 V power net allows up to 5 A of DC load current within thermal limits, while the remaining contacts carry digital control signals, making the connector suitable for mixed power-and-signal board interconnects.
How does tape-and-reel packaging benefit high-volume PCB assembly with the TSM-126-04-L-DH-A-K-TR?
Tape-and-reel packaging positions each 52-pin connector at a consistent orientation on a 24 mm or 32 mm carrier tape, enabling automated pick-and-place machines to place the component at speeds of 1,000 to 5,000 parts per hour with placement accuracy within ±0.1 mm. This eliminates hand-loading, reduces misalignment defects, and lowers per-unit assembly cost in high-volume PCB production runs compared to loose or tray-packaged alternatives.
