Applications
The TSM-135-01-LM-DH-A-K-TR is used in high-density board-to-board and board-to-module interconnect designs where a 70-position dual-row SMT terminal strip with a low-profile mounting style is required. It is commonly specified in industrial control systems, data acquisition modules, and embedded computing platforms where space constraints demand a low-profile connector with a large number of signal positions on standard 0.100" pitch.

Frequently Asked Questions
What does the LM suffix in TSM-135-01-LM-DH-A-K-TR indicate about the connector's mounting profile?
The LM suffix designates a low-profile mounting style, which reduces the above-board height of the 70-position SMT terminal strip compared to standard mounting variants. This lower profile is critical in slim enclosures and stacked board assemblies where clearance between the PCB and an adjacent surface or cover is less than 5 mm.
How many signal positions does the TSM-135-01-LM-DH-A-K-TR provide and how are they arranged across the connector body?
The TSM-135-01-LM-DH-A-K-TR provides 70 total positions arranged in a dual-row configuration with 35 positions per row on a 0.100" (2.54 mm) pitch. This high position count allows simultaneous routing of up to 70 independent signals or a mix of power, ground, and differential signal pairs in a single compact connector footprint.
For high-volume PCB manufacturing, is the TSM-135-01-LM-DH-A-K-TR compatible with standard automated assembly equipment?
Yes, the TR suffix confirms tape-and-reel packaging, making the 70-position, 0.100" pitch SMT connector fully compatible with automated pick-and-place machines and standard reflow soldering processes. The surface mount termination style supports high-volume production lines with reflow profiles up to 260°C peak temperature.
In what embedded computing or industrial designs is the 70-position dual-row TSM-135-01-LM-DH-A-K-TR typically used?
This 70-position, 2.54 mm pitch dual-row SMT terminal strip is typically specified in industrial data acquisition boards, modular PLC I/O expansion cards, and embedded computing backplanes where a large number of signals must be routed through a single low-profile connector. The 35 positions per row on 0.100" pitch align with standard 0.1" grid PCB layouts, simplifying routing on both the motherboard and daughter card sides.
