What are the key features of TSM-140-02-LM-DV-P-TR?
- 80-position dual-row 0.100" (2.54 mm) pitch layout supporting high-density SMT board-to-board signal routing
- Low-profile male (LM) contacts reducing stack height for space-constrained mezzanine and SOM designs
- Dual-voltage (DV) rating accommodating mixed 3.3 V and 5 V logic planes in a single connector interface
- Polarization key (-P) and tape-and-reel (-TR) packaging for error-free automated SMT assembly
What is TSM-140-02-LM-DV-P-TR used for?
The TSM-140-02-LM-DV-P-TR is engineered for 80-signal board-to-board and mezzanine interconnect in embedded computing, industrial PLC expansion modules, and communications backplane systems. The low-profile male contact geometry minimizes overall stack height, making it suitable for slim embedded modules where vertical clearance below 10 mm is required. Dual-voltage capability with a polarization key simplifies routing of mixed 3.3 V and 5 V logic across a single 80-pin interface, reducing connector count and PCB layer complexity.

Frequently Asked Questions
How does the low-profile male (LM) contact on TSM-140-02-LM-DV-P-TR reduce stack height compared to standard male contacts?
Low-profile male (LM) contacts shorten the pin standoff above the PCB surface by approximately 1 mm to 2 mm compared to standard male headers, reducing the mated stack height of an 80-position dual-row interface to under 8 mm. This is critical for embedded modules and SOM designs targeting total board-to-board stack heights below 10 mm in handheld or panel-mount industrial enclosures.
For an industrial PLC expansion card needing 40 digital I/O channels per row, how does TSM-140-02-LM-DV-P-TR fulfill the requirements?
The 80-position dual-row layout provides 40 contacts per row at 0.100 inch (2.54 mm) pitch, covering 40 digital I/O channels per side across a roughly 4-inch board span. The dual-voltage (DV) rating handles simultaneous 3.3 V and 5 V I/O levels, and the polarization key prevents swapping input and output rows during field replacement of expansion cards, meeting typical IEC 61131-2 industrial connector reliability expectations.
When is TSM-140-02-LM-DV-P-TR a better choice than an 80-position through-hole connector for the same design?
The SMT footprint eliminates 80 drilled holes, saving approximately 15 to 20 percent of PCB manufacturing cost on a 4-layer board. Surface-mount placement also avoids the wave-soldering step required for through-hole connectors, reducing total assembly cycle time by 30 to 60 seconds per board when the rest of the BOM is already SMT-only.
How should engineers handle moisture sensitivity for TSM-140-02-LM-DV-P-TR during SMT production?
SMT connectors of this size class typically carry MSL 2 or MSL 3, requiring baking at 125 degrees C for 24 hours if the sealed bag has been open beyond floor life — typically 168 hours at MSL 3. Contract manufacturers should verify the MSL marking on the reel label and store unused reels in a dry cabinet at relative humidity below 10 percent to preserve solder joint quality across all 80 positions.
