Frequently Asked Questions
How does the stainless steel (STL) hardware in TSM-120-02-STL-DH-P-TR improve connector reliability versus standard variants?
The STL designation indicates stainless steel hardware components, which provide significantly higher mechanical strength and corrosion resistance than standard plated steel or brass alternatives. For 40-position dual-row connectors subjected to repeated mating cycles or harsh industrial environments, stainless steel hardware extends operational lifetime and maintains contact integrity.
What board-to-board stacking clearance does the dual-height (DH) housing provide in TSM-120-02-STL-DH-P-TR mezzanine designs?
The DH (dual-height) housing on TSM-120-02-STL-DH-P-TR provides a taller body profile that creates additional clearance between stacked PCBs in mezzanine configurations. This extra space accommodates surface-mount components or routing traces under the connector body, useful in compact 40-pin stacking assemblies typical in embedded computing and industrial I/O boards.
Which SMT assembly processes are compatible with TSM-120-02-STL-DH-P-TR, and what reel size is typically available?
TSM-120-02-STL-DH-P-TR uses surface-mount termination and ships in tape-and-reel (TR) packaging, compatible with automated pick-and-place SMT reflow processes at standard reflow temperatures. SAMTEC typically offers standard reel quantities for 40-position connectors; buyers should confirm reel size with their distributor when planning volume production schedules.
In which high-vibration or defense-grade applications would TSM-120-02-STL-DH-P-TR be preferred over a standard TSM connector?
TSM-120-02-STL-DH-P-TR with stainless steel hardware is preferred in aerospace, defense, or industrial control applications where mechanical shock, vibration, or repeated mating with 40-position dual-row headers are expected. The combination of STL hardware, polarization, and a 2.54 mm pitch design ensures long-term mechanical retention and signal integrity in demanding environments.
