What are the key features of TSM-135-04-FM-DH-A-P-TR?
- 70-position dual-row female SMT terminal strip on a 0.100" (2.54 mm) pitch, providing 35 contacts per row for high-density board-to-board mating
- Friction-lock (FM) contact feature maintains positive retention force during and after mating, preventing unintentional connector separation under vibration
- Tape-and-reel (TR) packaging enables automated high-volume SMT pick-and-place assembly with 0.100" grid placement precision
What is TSM-135-04-FM-DH-A-P-TR used for?
The TSM-135-04-FM-DH-A-P-TR is designed for high-density female SMT interconnects on embedded computing modules, industrial backplane daughtercards, and instrumentation expansion boards requiring 70 contacts on a 0.100" pitch. The friction-lock feature keeps the connector seated reliably in vibration-prone environments such as motor drives and vehicle-mounted controllers. Tape-and-reel packaging suits automated assembly in high-volume production settings.

Frequently Asked Questions
How does the friction-lock (FM) feature of the TSM-135-04-FM-DH-A-P-TR prevent connector separation during operation?
The friction-lock contact design generates a controlled retention force across all 70 positions when mated, resisting axial pull-out forces that could cause intermittent connections. In vibration environments rated up to 15 G per IEC 60068-2-6, friction-lock SMT headers maintain electrical continuity without requiring secondary latching hardware, making them practical for industrial motor drives and mobile equipment PCBs on a 0.100" pitch grid.
Which SAMTEC male header mates with the TSM-135-04-FM-DH-A-P-TR 70-position female interface?
The TSM-135-04-FM-DH-A-P-TR female SMT strip mates with SAMTEC's corresponding male TSM or TSW series headers on the same 0.100" (2.54 mm) dual-row pitch. The 70-position count requires a 35-positions-per-row male counterpart to ensure correct contact alignment across the full 70-pin interface for signal and power distribution up to the rated current per contact.
How does TSM-135-04-FM-DH-A-P-TR compare to TSM-135-03-S-DH-A-P-TR for the same 70-position SMT application?
Both parts share the same 70-position, 0.100" dual-row SMT layout, but differ in contact style. The TSM-135-04-FM-DH-A-P-TR uses friction-lock (FM) contacts that provide higher pull-out retention force, while the -03-S variant uses a straight contact without the locking feature. Choose the FM version when vibration resistance is required; select the straight (-S) version when the lowest connector height below 5 mm is the priority.
