What are the key features of TSM-143-05-LM-DV-P-TR?
- 86-position dual-row layout at 0.100" (2.54 mm) pitch provides ample contact count for wide parallel buses and mixed signal/power interfaces
- Surface-mount termination with tape-and-reel (TR) packaging supports automated high-volume pick-and-place SMT assembly
- Dual-voltage (DV) configuration accommodates both signal and power contacts in the same connector body for versatile PCB designs
- Gold-plated contacts ensure low contact resistance and reliable mating over extended operating life
What is TSM-143-05-LM-DV-P-TR used for?
The TSM-143-05-LM-DV-P-TR is used in industrial control boards, embedded computing backplanes, and test fixture interfaces that require a high-density 86-pin dual-row surface-mount terminal strip at 2.54 mm pitch. Its dual-voltage capability makes it suitable for mixed power-and-signal edge connectors on PCIe riser cards and peripheral expansion modules. The tape-and-reel format enables seamless integration into automated SMT manufacturing lines for high-volume production.

Frequently Asked Questions
What pitch and contact count does the TSM-143-05-LM-DV-P-TR terminal strip provide?
The TSM-143-05-LM-DV-P-TR provides 86 total contact positions in a dual-row configuration at a 0.100" (2.54 mm) pitch, giving 43 contacts per row. This 2.54 mm pitch is the industry-standard spacing for a wide range of through-hole and SMT connector mating systems used in embedded computing and industrial control.
What does the DV (dual-voltage) designation mean in the TSM-143-05-LM-DV-P-TR, and how does it benefit mixed power-and-signal board designs?
The DV designation in the TSM-143-05-LM-DV-P-TR indicates dual-voltage capability, meaning the connector is designed to handle both signal-level and higher-voltage power contacts within the same 86-position strip. This allows designers to consolidate signal and power distribution in a single connector body, reducing BOM complexity and PCB edge connector count for systems with multiple voltage rails such as 3.3 V, 5 V, and 12 V.
For an 80-channel industrial I/O backplane, does the TSM-143-05-LM-DV-P-TR have adequate contact positions to handle signal and ground pins?
Yes. The TSM-143-05-LM-DV-P-TR provides 86 contact positions at 2.54 mm pitch, which is sufficient to accommodate 80 signal channels plus at least 6 dedicated power or ground pins on a single dual-row connector. At 2.54 mm pitch, the total connector length is approximately 55 mm, fitting on standard 3U or 6U industrial card edge profiles.
How does surface-mount termination of the TSM-143-05-LM-DV-P-TR compare to through-hole terminal strips of similar 86-pin count for PCB assembly?
The surface-mount TSM-143-05-LM-DV-P-TR eliminates the need for through-hole drilling across 86 positions, saving PCB manufacturing time and reducing drill tooling cost. SMT termination also allows the connector to be placed on the same reflow pass as other surface-mount components, whereas a through-hole 86-pin strip requires a separate wave-solder or hand-solder step, increasing production cycle time.
