Frequently Asked Questions
How many positions does the TSM-128-01-LM-DH-A-K-TR provide, and what is the connector pitch?
The TSM-128-01-LM-DH-A-K-TR offers 56 positions arranged in a single-row configuration on a standard 2.54 mm (0.100") pitch. This combination delivers a high-density interconnect in a compact footprint, fitting 56 signal or power pins across approximately 139 mm of board edge length.
Does the TSM-128-01-LM-DH-A-K-TR support automated PCB assembly, and in what packaging format is it supplied?
Yes, the TSM-128-01-LM-DH-A-K-TR is supplied in tape-and-reel (TR) packaging, specifically designed for automated SMT pick-and-place machines. The reel format ensures reliable component orientation and consistent 2.54 mm pitch placement, supporting high-volume production with minimal manual handling steps.
In which embedded computing or industrial applications is a 56-position 2.54 mm pitch terminal strip most commonly used?
A 56-position 2.54 mm pitch surface mount terminal strip like the TSM-128-01-LM-DH-A-K-TR is commonly used in FPGA development boards, industrial PLC backplanes, data acquisition cards, and single-board computer expansion interfaces. The 56-pin count provides enough I/O for parallel bus interfaces running at up to 50 MHz or GPIO-rich embedded control systems.
How does the low-mount (LM) variant compare to standard-height SAMTEC TSM connectors for board stacking clearance?
The LM (low-mount) variant of the TSM-128-01-LM-DH-A-K-TR reduces the mated connector height to approximately 3.5 mm above the PCB surface, compared to 8 mm or more for standard-height configurations. This is critical in stacked PCB assemblies where board-to-board spacing must remain below 5 mm, such as in rack-mounted embedded computing modules with 1U chassis constraints.
