Frequently Asked Questions
How many positions and rows does the TSM-125-03-LM-DH-A-K-TR provide, and what pitch does it use?
The TSM-125-03-LM-DH-A-K-TR provides 50 positions arranged in a dual-row configuration with a 0.100" (2.54 mm) pitch. This standard pitch makes it compatible with a wide range of mating connectors and simplifies PCB layout for high pin-count applications in industrial and embedded systems.
Can TSM-125-03-LM-DH-A-K-TR be used in automated SMT assembly processes?
Yes, this connector is designed for surface mount technology (SMT) assembly and is packaged on tape and reel (TR suffix) for pick-and-place automation. The SMT termination style supports standard reflow soldering at temperatures up to 260°C, making it suitable for high-volume automated PCB production lines.
In what applications is a 50-position terminal strip like the TSM-125-03-LM-DH-A-K-TR commonly deployed?
A 50-position dual-row terminal strip is commonly used in test and measurement equipment, industrial control boards, and embedded processor modules where 50 signal lines must be routed across a single connector. It also appears in backplane assemblies and FPGA development boards needing 50-pin or wider parallel bus interfaces.
How does the low-profile mounting option of TSM-125-03-LM-DH-A-K-TR compare to standard-profile variants?
The 'LM' designation in TSM-125-03-LM-DH-A-K-TR indicates a low-profile mounting height, typically around 3.00 mm above the PCB, compared to standard-profile versions that stand taller. This reduction of several millimeters in board clearance is critical for compact enclosures, stacked PCB designs, or systems with tight Z-axis constraints of less than 5 mm.
