What are the key features of TSM-143-02-LM-DV-P-TR?
- 86-position dual-row 2.54 mm pitch SMT terminal strip enabling high pin-count board interconnection
- Low-profile mounting post design reducing overall connector height for space-constrained enclosures
- Gold-plated contacts providing reliable low-resistance connections rated for multiple mating cycles
- Tape-and-reel format enabling automated pick-and-place assembly at high production volumes
- Standard 2.54 mm pitch compatible with IDC ribbon cable headers and breadboard prototyping grids
What is TSM-143-02-LM-DV-P-TR used for?
The TSM-143-02-LM-DV-P-TR suits low-profile embedded computing modules, industrial I/O expansion cards, and wire-to-board assemblies where 86 signal or mixed-signal lines must cross a PCB interface with minimal vertical clearance. Its standard 2.54 mm pitch enables direct mating with IDC ribbon cables rated at 1 A per contact for fieldbus and control wiring in factory automation. The tape-and-reel packaging supports uninterrupted high-volume production in consumer electronics and test equipment manufacturing.

Frequently Asked Questions
How does the low-profile mounting post of TSM-143-02-LM-DV-P-TR differ from the standard 4 mm post variant?
The LM (low-profile mounting) variant of the TSM-143-02-LM-DV-P-TR uses a shorter mounting post compared to the 4 mm post on standard variants, reducing the total connector height above the PCB by approximately 2 mm. This makes it suitable for enclosures where the board-to-cover clearance is under 8 mm and the full 86-position dual-row connector must fit without mechanical interference.
What current and signal capacity does the TSM-143-02-LM-DV-P-TR 86-position connector support?
Each of the 86 contacts in the TSM-143-02-LM-DV-P-TR is rated to carry up to 3 A when used for power distribution, or supports differential and single-ended signal lines at frequencies up to several hundred MHz with the 2.54 mm pitch spacing. The dual-row layout also allows alternating signal-ground assignments to achieve controlled impedance of approximately 50 Ω for sensitive digital signals.
In which industrial automation scenarios does the TSM-143-02-LM-DV-P-TR provide the best fit?
The TSM-143-02-LM-DV-P-TR is most appropriate for PLC I/O expansion modules, DCS controller backplanes, and relay output cards requiring 86 mixed-signal connections routed over short distances of under 30 cm. Its 2.54 mm pitch matches standard IDC cables used in 24 V industrial digital I/O wiring, and the SMT footprint integrates directly into reflow-soldered production boards without manual through-hole insertion.
How does tape-and-reel packaging of TSM-143-02-LM-DV-P-TR reduce assembly costs compared to bulk or tray packaging?
Tape-and-reel packaging allows the TSM-143-02-LM-DV-P-TR to be fed directly into pick-and-place feeders at speeds of several hundred placements per hour, eliminating the manual singulation step required for bulk-packed connectors. Standard reels contain 500 to 1000 pieces, supporting several hours of uninterrupted SMT line operation and reducing component handling errors by keeping 86-position connectors oriented and protected until placement.
