Frequently Asked Questions
What is the pin count and pitch of the TSM-127-02-STL-DH-A-K-TR connector?
The TSM-127-02-STL-DH-A-K-TR has 54 positions arranged in a dual-row layout with a 2.54 mm (0.100 inch) pitch. This standard spacing accommodates a wide range of mating headers and simplifies PCB layout for high-density interconnect designs.
Which PCB assembly processes are compatible with the TSM-127-02-STL-DH-A-K-TR surface mount design?
This connector features SMT tails designed for reflow soldering, making it compatible with standard surface mount assembly processes. The solder reflow temperature range typically follows J-STD-020 profiles up to 260°C peak, supporting lead-free assembly in automated production lines.
In what industrial or embedded applications is the TSM-127-02-STL-DH-A-K-TR commonly used?
The TSM-127-02-STL-DH-A-K-TR suits applications requiring 54 signal connections in a compact form factor, including industrial backplane systems, test and measurement instrumentation, data acquisition cards, and embedded processor modules. Its dual-row 2.54 mm pitch format supports reliable multi-channel signal routing at voltages up to 250 V.
How does the TSM-127-02-STL-DH-A-K-TR compare to single-row terminal strips for space-constrained PCB designs?
The dual-row configuration of the TSM-127-02-STL-DH-A-K-TR provides 54 positions in roughly half the board length required by a comparable single-row strip, saving significant PCB real estate. This makes it advantageous for designs with limited space where routing 54 signals across a 2.54 mm pitch footprint is required.
