What are the key features of TSM-112-01-LM-DH-A-K-TR?
- 24-position dual-row layout at 0.100" (2.54 mm) pitch for compact mid-density board-to-board signal routing
- Low-profile 'LM' mounting reduces connector height above PCB, optimizing designs with tight Z-axis clearance constraints
- Tape-and-reel (TR) packaging supports pick-and-place automation for high-volume SMT manufacturing
What is TSM-112-01-LM-DH-A-K-TR used for?
The TSM-112-01-LM-DH-A-K-TR is suited for embedded microcontroller boards, sensor interface cards, and compact industrial I/O modules needing 24 signals via a low-profile SMT connector. The dual-row 0.100" pitch format accommodates standard GPIO expansion headers and 16-bit bus interfaces with 8 control lines in a minimal board footprint. Its low-profile height makes it appropriate for slim enclosures and stacked PCB assemblies with less than 5 mm vertical clearance.

Frequently Asked Questions
How many contacts per row does TSM-112-01-LM-DH-A-K-TR offer, and at what spacing?
The TSM-112-01-LM-DH-A-K-TR provides 24 total contacts distributed across 2 rows, giving 12 contacts per row at a 0.100" (2.54 mm) pitch. This standard dual-row layout is compatible with widely available mating receptacles and supports 24-pin parallel interfaces such as GPIO headers and low-speed parallel buses.
In a stacked PCB enclosure with only 4 mm vertical clearance, is TSM-112-01-LM-DH-A-K-TR a suitable choice?
The 'LM' (low-profile) suffix indicates a reduced above-board height, typically around 3.00 mm, which can fit within a 4 mm clearance after accounting for solder joint thickness. This makes the TSM-112-01-LM-DH-A-K-TR one of the preferred options for slim consumer electronics or tightly stacked industrial module designs where standard-height connectors exceeding 5 mm would not fit.
How does TSM-112 (24-position) compare to TSM-114 (28-position) when selecting for a 20-signal interface?
For a 20-signal interface, the TSM-112 (24 positions) provides 4 spare contacts for ground or power routing within the same connector, while the TSM-114 (28 positions) offers 8 spare contacts. The TSM-112 is the more compact choice, saving approximately 10.16 mm (4 x 2.54 mm) in board length while still accommodating the 20 required signals plus 4 auxiliary lines.
Does the TSM-112-01-LM-DH-A-K-TR support RoHS-compliant board builds?
Yes, the 'A-K' suffix in the part number indicates RoHS-compliant construction with halogen-free materials and a tin-plated finish free of restricted substances. This allows the TSM-112-01-LM-DH-A-K-TR to be used in lead-free PCB assemblies meeting IPC and EU RoHS Directive requirements, supporting environmental compliance across 24-pin connector applications.
