What are the key features of TSM-140-04-T-DV-P-TR?
- 80-position dual-row SMT layout on 0.100" (2.54 mm) pitch with polarized DV keying to prevent incorrect mating and mixed-voltage errors
- 3 A per-pin tin-plated contact rating enabling moderate power distribution alongside signal connections in compact board-to-board assemblies
- Extended temperature range from -65°C to +150°C for reliable operation in harsh thermal environments including automotive under-hood and industrial control enclosures
What is TSM-140-04-T-DV-P-TR used for?
The TSM-140-04-T-DV-P-TR is suited for board-to-board and backplane interconnects in industrial automation, embedded computing modules, and test and measurement instruments requiring 80 contacts at standard 0.100" pitch. The dual-voltage keying (DV) feature prevents incorrect card insertion in mixed-voltage chassis environments, protecting both boards and components. Its tape-and-reel packaging enables automated pick-and-place assembly in high-volume SMT manufacturing lines.

Frequently Asked Questions
What does the DV (dual-voltage) keying feature of the TSM-140-04-T-DV-P-TR prevent during board installation?
The DV keying on the TSM-140-04-T-DV-P-TR physically prevents mating with a connector on a board configured for a different voltage rail, such as connecting a 3.3 V card to a 5 V backplane slot. This mechanical polarization eliminates cross-voltage insertion errors that could damage components or corrupt signals across the 80 pins. The keying is especially valuable in mixed-voltage chassis with multiple card types sharing the same backplane.
How many amps per pin can the TSM-140-04-T-DV-P-TR carry, and how does this enable power plus signal on the same connector?
Each contact in the TSM-140-04-T-DV-P-TR is rated at 3 A. With 80 total pins in a dual-row 0.100" pitch layout, designers can allocate a subset of pins to power distribution—for example, 4 pins at 3 A each supply 12 A total—while using the remaining contacts for data, control, and ground signals. This mixed power-and-signal capability reduces the need for a separate power connector on compact embedded boards.
Is the TSM-140-04-T-DV-P-TR suitable for automated SMT assembly, and what tape configuration does it ship in?
Yes. The -TR suffix in TSM-140-04-T-DV-P-TR indicates tape-and-reel packaging, which is compatible with standard automated pick-and-place SMT assembly equipment. The surface-mount termination style and reel format allow high-speed component placement at PCB assembly facilities, reducing per-unit handling time compared to loose-piece connectors in high-volume production exceeding 1000 units per run.
