Frequently Asked Questions
How many positions does the TSM-134-03-LM-DH-A-P-TR provide, and what pitch does it use?
The TSM-134-03-LM-DH-A-P-TR provides 68 positions at a 2.54 mm (0.100 inch) pitch in a dual-row, dual-height surface-mount configuration. This gives designers 34 contacts per row for routing a large number of signals or mixed power-and-signal combinations on industrial control cards, embedded processor boards, and backplane interconnect systems within a standard through-hole grid-compatible footprint.
Which high-channel-count embedded board applications are best matched to the TSM-134-03-LM-DH-A-P-TR?
Industrial programmable logic controllers (PLCs) with 64+ discrete I/O channels, multi-axis motor control cards, and embedded SBC (single-board computer) expansion boards benefit from the TSM-134-03-LM-DH-A-P-TR's 68-position capacity at 2.54 mm pitch. The dual-height feature also suits stacked daughterboard architectures common in data acquisition systems sampling 32 or more differential input channels at sampling rates of 100 kHz or higher.
What does the dual-height (DH) designation mean for mating connector compatibility with the TSM-134-03-LM-DH-A-P-TR?
The dual-height (DH) designation means the TSM-134-03-LM-DH-A-P-TR accommodates two different mating connector or pin header heights, typically supporting both standard 8.5 mm and taller 11.0 mm mating post lengths. This flexibility allows the same footprint to accept different board-stacking heights in a product family, reducing the need for separate connector variants when changing PCB separation distance from 5 mm to 8 mm in stacked enclosure designs.
Does the tape-and-reel packaging of the TSM-134-03-LM-DH-A-P-TR support standard SMT feeder widths?
Yes, the TSM-134-03-LM-DH-A-P-TR in TR (tape-and-reel) format is packaged in carrier tape compatible with standard 24 mm or 32 mm SMT feeder systems, enabling direct loading into automated pick-and-place machines without manual component handling. This reduces placement cycle time on production lines processing hundreds of boards per hour, and the standardized reel format minimizes feeder changeover downtime compared to tray-fed large connectors.
