Frequently Asked Questions
How many signal positions does TSM-128-04-SM-DH-A-P-TR provide and at what pitch?
The TSM-128-04-SM-DH-A-P-TR provides 56 positions arranged in a dual-row format with a 0.100 inch (2.54 mm) pitch. This configuration allows designers to route 56 individual signals across a single connector interface, making it practical for FPGA breakout boards, data acquisition systems, and modular backplane designs.
Does the tape-and-reel packaging of TSM-128-04-SM-DH-A-P-TR suit high-volume automated SMT assembly?
Yes. The TR suffix indicates tape-and-reel packaging, which is compatible with standard pick-and-place equipment and reflow soldering at typical SMT peak temperatures around 260°C. This packaging reduces manual handling and supports high-volume production runs while maintaining consistent placement accuracy for the 56-position footprint.
What are the key differences between TSM-128-04-SM-DH-A-P-TR and a comparable through-hole terminal strip?
The surface mount design of TSM-128-04-SM-DH-A-P-TR eliminates the need for drilled through-holes, reducing PCB layer stack requirements and enabling denser routing on adjacent layers. With 56 positions at 0.100 inch pitch, it occupies less board real estate than through-hole equivalents and integrates directly into standard SMT assembly lines.
For which industrial or computing applications is TSM-128-04-SM-DH-A-P-TR typically specified?
This connector is commonly specified in industrial I/O expansion cards, embedded single-board computers, and test and measurement instruments that require 56 or more signal channels on a surface mount interface. Its dual-row 0.100 inch pitch format is well established in instrumentation, robotics controllers, and FPGA development platforms needing reliable multi-pin board-to-board connections.
