Frequently Asked Questions
What does the LM designation mean for TSM-121-01-LM-DH-P-TR board height clearance?
LM stands for low mount, meaning the TSM-121-01-LM-DH-P-TR has a reduced mating height compared to standard configurations. This is critical in stacked PCB designs where board-to-board clearance is limited, allowing a 42-position dual-row 0.100" pitch connector to fit within tight enclosure constraints.
Can TSM-121-01-LM-DH-P-TR handle both signal and power contacts in a 42-position layout?
Yes. The 42-position dual-row configuration of TSM-121-01-LM-DH-P-TR with 0.100" (2.54 mm) pitch allows designers to allocate contacts for both signal lines and low-current power distribution within the same connector footprint, reducing component count on boards for industrial and embedded system applications.
How does tape-and-reel packaging benefit procurement and production planning for TSM-121-01-LM-DH-P-TR?
Tape-and-reel (TR) packaging enables automated SMT pick-and-place loading for the TSM-121-01-LM-DH-P-TR, supporting continuous reel-based feeding during high-volume reflow assembly runs. This reduces manual handling errors and shortens cycle time, which is especially beneficial when placing 42-pin dual-row connectors at high placement rates.
