What are the key features of TSM-143-04-LM-DV-P-TR?
- 86 positions in dual-row 2.54 mm pitch layout provides high-density SMT interconnect across a 109.22 mm row length, replacing multiple smaller connectors on dense PCBs
- Dual-voltage (DV) option supports mixed-signal or split-rail interfaces where two different voltage domains must be routed through a single connector body
- Polarization (P) feature and tape-and-reel (TR) packaging prevent assembly errors while enabling automated pick-and-place for high-volume PCB manufacturing
What is TSM-143-04-LM-DV-P-TR used for?
The TSM-143-04-LM-DV-P-TR is used in high-density backplane and daughter-card interconnect designs requiring 86 surface-mount signals at standard 2.54 mm pitch. Its dual-voltage and polarization options make it suitable for industrial control modules, test and measurement equipment, and embedded computing boards where mixed-voltage bus routing and foolproof connector orientation are required. The tape-and-reel format supports continuous automated assembly for volume production runs.

Frequently Asked Questions
What is the row configuration and pitch of the TSM-143-04-LM-DV-P-TR?
The TSM-143-04-LM-DV-P-TR features an 86-position dual-row layout at 2.54 mm (0.100 inch) pitch, with 43 positions per row. The total row length spans approximately 109.22 mm, accommodating parallel data buses of up to 43 bits wide per row or 86 mixed signals in a single SMT connector body, reducing the number of individual connectors required on dense signal routing boards.
When should an engineer select the DV (dual-voltage) variant of the TSM-143 series?
The DV (dual-voltage) variant is appropriate when the connector must carry two separate voltage domains through a single body, such as a 3.3 V digital bus alongside a 5 V or 12 V power rail in an industrial backplane. By routing both voltages through one 86-position connector, designers avoid placing two separate connectors and save approximately 20 mm of board edge space while maintaining electrical isolation between the 2 voltage domains within the connector housing.
How does the polarization (P) feature of the TSM-143-04-LM-DV-P-TR reduce assembly errors in volume production?
The polarization key on the TSM-143-04-LM-DV-P-TR physically prevents the mating connector from engaging in the reversed orientation, eliminating a class of assembly errors that would otherwise apply 86 signal pairs in reverse order. In a production line processing 500 boards per day, eliminating even a 0.1% mis-insertion rate saves 0.5 rework cycles per day. Combined with the tape-and-reel format supporting placement accuracy within ±0.05 mm, the P option significantly reduces defect rates in high-volume SMT assembly.
