What are the key features of TSM-140-04-LM-DV-P-TR?
- 80-position dual-row terminal strip on 0.100" (2.54 mm) pitch supports mixed signal and power distribution in a single connector body
- Dual-voltage (DV) contact design accommodates both power and signal contacts within the same 80-position connector for flexible system architecture
- Polarization peg (P suffix) prevents mis-mating and incorrect orientation in multi-connector high-density board assemblies
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume and high-throughput production lines
What is TSM-140-04-LM-DV-P-TR used for?
The TSM-140-04-LM-DV-P-TR is suited for board-to-board power and signal distribution in industrial PLC backplanes, rack-mount computing systems, and high-density I/O expansion cards where 80 connections and dual-voltage capability are required. The 0.100" pitch provides robust mechanical contact suitable for vibration-prone environments such as factory automation and transportation electronics. Tape-and-reel packaging enables efficient automated assembly for medium-to-high volume manufacturing runs.

Frequently Asked Questions
What is the contact pitch of the TSM-140-04-LM-DV-P-TR, and how does it compare to the SFM series 0.050" pitch connectors?
The TSM-140-04-LM-DV-P-TR uses a 0.100" (2.54 mm) pitch, which is exactly double the 0.050" (1.27 mm) pitch of the SFM series. This means the 80-position TSM-140 body spans approximately 100 mm (40 positions × 2.54 mm per row), compared to about 53 mm for the same-position SFM-140. The wider pitch provides more robust solder joints and better mechanical retention, making TSM better suited for power contacts and vibration environments.
What does the DV designation in TSM-140-04-LM-DV-P-TR indicate about its contact capability?
The DV designation stands for dual-voltage, meaning the connector is designed to carry both signal-level and higher-voltage power contacts within the same 80-position housing. This allows a single TSM-140-04-LM-DV-P-TR to route 3.3 V or 5 V logic signals alongside 12 V or 24 V power rails, reducing the need for separate power and signal connectors on the PCB and simplifying board-to-board cable harness design.
How does the LM (low-profile) variant of TSM-140-04-LM-DV-P-TR benefit stacked PCB enclosure designs?
The LM (low-profile mating) designation reduces the connector's unmated height above the PCB surface, allowing for tighter board-to-board stacking clearances, typically under 8 mm including the mated stack. In rack-mount or compact industrial enclosure designs where vertical board spacing is constrained to 1U (44 mm) or less, the LM profile enables fitting additional circuit boards within the chassis. The 80-position count retains full I/O density despite the reduced profile.
