Frequently Asked Questions
How many positions does the TSM-127-04-SS-DH-A-K-TR terminal strip provide and what pitch does it use?
The TSM-127-04-SS-DH-A-K-TR provides 54 positions arranged in a dual-row configuration with a 2.54 mm (0.100") pitch. This standard pitch spacing ensures compatibility with a wide range of mating connectors and PCB footprints, making it straightforward to integrate into existing board designs without custom routing adjustments.
Is the TSM-127-04-SS-DH-A-K-TR compatible with automated SMT assembly lines?
Yes, the TSM-127-04-SS-DH-A-K-TR is supplied in tape-and-reel format as indicated by the TR suffix, which is specifically designed for automated SMT pick-and-place assembly. The surface-mount termination style is compatible with standard reflow soldering processes at typical peak temperatures of 260°C, enabling high-throughput production without manual placement. The 2.54 mm pitch also simplifies pad design on standard FR4 PCBs.
Why choose stainless steel contacts in the TSM-127-04-SS-DH-A-K-TR over standard brass for industrial applications?
Stainless steel contacts in the TSM-127-04-SS-DH-A-K-TR offer significantly higher corrosion resistance than standard brass contacts, which is critical in industrial environments exposed to humidity, chemical vapors, or temperature cycling between -40°C and +85°C. For embedded computing and control systems in factory automation or outdoor equipment, stainless steel contacts maintain stable contact resistance over the product lifetime across all 54 positions, reducing field failure rates compared to brass alternatives.
