What are the key features of TSM-125-01-TM-DH-A-K-TR?
- 50-position dual-row terminal strip with 2.54 mm (0.100 inch) pitch and 25 pins per row for high-count SMT board-to-board connections in industrial systems
- Top-mount (TM) configuration allows board-edge placement for accessible signal distribution and daughtercard connector applications
- Surface mount design with tape-and-reel packaging for automated pick-and-place SMT assembly in high-volume PCB production
What is TSM-125-01-TM-DH-A-K-TR used for?
The TSM-125-01-TM-DH-A-K-TR 50-position terminal strip is ideal for high-density board-to-board and backplane interconnect in industrial controllers, embedded computing platforms, and data acquisition systems requiring a full 50-pin signal interface in a single 2.54 mm pitch connector. Its top-mount configuration suits board-edge daughtercard connections where signal distribution to expansion boards or peripheral modules is required. This terminal strip is commonly used in PLC I/O modules, automation system racks, and test fixture motherboards where 50-pin standardized 0.100 inch pitch connectivity is specified.

Frequently Asked Questions
What does the top-mount (TM) configuration of TSM-125-01-TM-DH-A-K-TR mean for PCB placement and mating direction?
The top-mount (TM) configuration of TSM-125-01-TM-DH-A-K-TR means the connector is designed to be placed and soldered on the top surface of the PCB with the mating direction oriented upward or perpendicular to the board plane. This allows a daughter card or mating socket to plug in from above, making it suitable for 50-position 2.54 mm pitch board-stacking and daughtercard applications in industrial backplane systems and expansion card designs.
For a 50-I/O industrial PLC module, how does TSM-125-01-TM-DH-A-K-TR simplify the I/O connector architecture?
A single 50-position TSM-125-01-TM-DH-A-K-TR consolidates all 50 I/O signals of a PLC module into one 2.54 mm pitch dual-row connector, providing 25 signals per row across a single SMT footprint. This eliminates the need for multiple smaller 10 or 20-position connectors, reduces PCB routing complexity, and ensures that all 50 digital or analog I/O channels can be accessed through one standardized mating interface on industrial rack-mount equipment.
How does the 50-position TSM-125-01-TM-DH-A-K-TR compare to the 48-position TSM-124-02-L-DH-A-K-TR for backplane applications?
The TSM-125-01-TM-DH-A-K-TR provides 50 contact positions with a top-mount configuration versus the 48 positions and standard L-mount of TSM-124-02-L-DH-A-K-TR, both at 2.54 mm (0.100 inch) pitch. Engineers choose the 50-position TSM-125 for backplane architectures that need exactly 25 pins per row aligned to 50-pin bus standards, while the 48-position TSM-124 suits designs based on 24-pin row groupings, with mount style selection driven by daughtercard insertion direction requirements.
