Frequently Asked Questions
What total pin count and pitch does the TSM-135-04-TL-DH-A-K-TR provide?
The TSM-135-04-TL-DH-A-K-TR features 70 total contacts arranged in a dual-row layout on a standard 0.100 inch (2.54 mm) pitch, which is compatible with common PCB grid spacings used across industrial and embedded computing designs.
How do the through-hole locating pegs on this SAMTEC surface mount strip improve assembly reliability?
Through-hole locating pegs mechanically register the 70-position connector body to the PCB during reflow, preventing the part from shifting on 0.100 inch pitch pads before solder solidifies, which reduces misalignment defects in automated SMT production lines.
Can the TSM-135-04-TL-DH-A-K-TR be used in tape-and-reel automated placement for high-volume builds?
Yes. The TR suffix confirms tape-and-reel packaging, enabling this 70-pin dual-row terminal strip to be loaded into standard SMT feeders; this eliminates hand-placement of the connector and maintains consistent 0.100 inch pitch placement across high-volume PCB production runs.
What industries and design types commonly specify a 70-position 0.100 inch pitch surface mount terminal strip?
Industrial automation controllers, test and measurement backplanes, and embedded single-board computers frequently use 70-pin surface mount strips at 0.100 inch pitch to interconnect signal, power, and ground rails between modular PCB sections or daughter-card interfaces.
