Frequently Asked Questions
What distinguishes the TM termination style in TSM-126-04-TM-DH-A-K-TR from other SAMTEC terminal strip variants?
The TM designation in TSM-126-04-TM-DH-A-K-TR specifies a top-mount termination style, where mating occurs perpendicular to the PCB surface. This enables vertical board-to-board stacking configurations, contrasting with horizontal H-style variants. The 52-position dual-row layout with 0.100 inch pitch remains consistent, but the mating direction supports different mechanical assembly orientations.
How many signal connections can the TSM-126-04-TM-DH-A-K-TR accommodate per connector unit?
The TSM-126-04-TM-DH-A-K-TR accommodates 52 signal connections total, arranged in 2 rows of 26 pins each at 0.100 inch (2.54 mm) pitch. This dual-row DH configuration allows dense signal routing within a standard 0.100 inch grid, supporting parallel bus architectures, digital I/O expansion, and multi-channel data interfaces in a single connector.
Is the TSM-126-04-TM-DH-A-K-TR available in tape-and-reel packaging for automated manufacturing?
Yes, the TR suffix in TSM-126-04-TM-DH-A-K-TR confirms availability in tape-and-reel packaging, which supports automated pick-and-place assembly on standard SMD production lines. Tape-and-reel delivery is essential for high-volume PCB manufacturing with reflow soldering, reducing manual handling and placement errors for this 52-position surface mount connector.
What PCB applications benefit most from a 52-position dual-row terminal strip like TSM-126-04-TM-DH-A-K-TR?
A 52-position dual-row terminal strip benefits applications such as FPGA daughtercard interfaces, multi-channel sensor array boards, industrial backplane connectors, and embedded processor expansion modules requiring more than 40 pins in a single connector. The 0.100 inch pitch is compatible with standard PCB routing grids, and the SMD format simplifies board fabrication compared to through-hole alternatives.
