Frequently Asked Questions
What does the friction lock (F) suffix mean in TSM-122-04-F-DH-P-TR and how does it benefit connector retention?
The F suffix in TSM-122-04-F-DH-P-TR indicates a friction lock feature, which adds mechanical retention force between the terminal strip and its mating connector. This increases resistance to accidental unmating in environments with vibration or mechanical shock, making the 44-position strip more reliable in industrial automation, transportation electronics, and ruggedized embedded systems where standard press-fit connections might loosen over time.
How does the 44-position count of TSM-122-04-F-DH-P-TR compare to 56-position variants for signal channel planning?
The TSM-122-04-F-DH-P-TR provides 44 total positions (22 per row) at 0.100 inch pitch, compared to 56-position variants that provide 28 per row. Designers with fewer than 44 signal or power lines can use this part to avoid the wasted footprint and cost of larger connectors, while maintaining identical 0.100 inch pitch compatibility with standard mating headers across the SAMTEC TSM series.
Is TSM-122-04-F-DH-P-TR suitable for applications requiring compliance with environmental regulations?
SAMTEC TSM series terminal strips are manufactured with RoHS-compliant materials and lead-free finishes, making the TSM-122-04-F-DH-P-TR appropriate for products sold in markets subject to EU RoHS and REACH regulations. The lead-free solder termination is compatible with standard SAC305 reflow profiles at peak temperatures up to 260°C, supporting environmentally responsible PCB manufacturing.
For a new industrial control board design, what PCB layout footprint does TSM-122-04-F-DH-P-TR require?
The TSM-122-04-F-DH-P-TR has a dual-row layout with 22 positions per row at a 0.100 inch (2.54mm) pitch, so the connector spans approximately 2.2 inches (55.88mm) along the row axis. The dual-height (DH) body adds board clearance above the PCB surface, which designers should account for in 3D clearance checks when placing components on the opposite or adjacent board in a stacked assembly.
