Frequently Asked Questions
What is the total contact count and row arrangement of the TSM-143-04-L-DV-P-TR terminal strip?
The TSM-143-04-L-DV-P-TR provides 86 positions in a dual-row configuration with 43 contacts per row and a 2.54 mm (0.100 inch) pitch. This standard pitch matches the most common prototyping and production PCB grid, allowing direct use with 2.54 mm headers, breadboards, and IDC cable assemblies carrying up to 86 signal lines.
How do the 4 mm mounting posts on the TSM-143-04-L-DV-P-TR improve PCB assembly reliability?
The 4 mm mounting posts anchor the 86-position connector mechanically to the PCB before and during reflow, preventing the part from shifting more than 0.1 mm in x or y during solder paste melting at peak temperatures of 260°C. This alignment ensures all 86 SMT pads make reliable solder joints simultaneously, reducing rework rates in high-volume production runs.
For which embedded computing and industrial control applications is the TSM-143-04-L-DV-P-TR the right choice?
The TSM-143-04-L-DV-P-TR suits backplane bus interfaces in PLCs and DCS modules where 86 digital or analog lines must span board-to-board distances up to 10 mm. Its 2.54 mm pitch is compatible with standard ribbon cable IDC connectors rated at 1 A per contact, making it appropriate for mixed-signal I/O expansion boards, motor drive interface cards, and industrial fieldbus adapters.
What procurement advantage does the tape-and-reel format of TSM-143-04-L-DV-P-TR offer for manufacturing?
The TR (tape-and-reel) packaging of the TSM-143-04-L-DV-P-TR allows automated pick-and-place machines to feed the 86-position connector at production rates of hundreds of placements per hour, eliminating manual loading and reducing placement errors compared to loose-piece bulk packaging. Standard reel quantities typically contain 500 to 1000 pieces, supporting uninterrupted production runs without operator intervention for hours at a time.
