Frequently Asked Questions
How many signal positions does the TSM-127-04-S-DH-P-TR support, and what is its pin pitch?
The TSM-127-04-S-DH-P-TR supports 54 positions in a dual-row configuration with 0.100" (2.54 mm) pitch, delivering 27 contacts per row for standard PCB grid signal routing in industrial and embedded communications boards.
What role does the polarizing post play in the TSM-127-04-S-DH-P-TR, and how does it benefit board assembly?
The polarizing post (P designation) acts as a mechanical keying feature preventing reverse or incorrect mating, protecting 54 signal contacts from damage. It is especially valuable during field installation where the connector operates across temperatures from -55°C to +125°C.
Which types of PCB designs benefit most from choosing the TSM-127-04-S-DH-P-TR over fewer-pin SAMTEC terminal strips?
Designs requiring 54 dedicated signal lines, such as FPGA configuration interfaces, parallel bus backplanes, or multi-channel data acquisition boards, benefit from this connector's dual-row 2.54 mm pitch layout that maximizes signal density within a compact board footprint.
Is the TSM-127-04-S-DH-P-TR suitable for automated SMT production, and what packaging quantity is available on tape and reel?
Yes, the TR suffix confirms tape-and-reel packaging for automated pick-and-place assembly, with typical reel quantities of 500 or 1,000 pieces per reel, supporting high-volume production of 54-pin dual-row connector assemblies while maintaining each connector's gold-plated contact quality.
