Frequently Asked Questions
What does the triple-row (SM) configuration of TSM-120-03-SM-DH-P-TR mean for board layout and signal capacity?
The SM designation in TSM-120-03-SM-DH-P-TR indicates a triple-row contact arrangement providing 40 positions across 3 parallel rows at a 2.54 mm pitch. This allows more signal connections per connector body length than a single- or dual-row part, making it advantageous for dense embedded system boards where connector width must be minimized while maintaining a high pin count.
How does the press-fit (P) option improve PCB assembly reliability for the TSM-120-03-SM-DH-P-TR?
The press-fit (P) feature on the TSM-120-03-SM-DH-P-TR anchors the connector body to the PCB before and during the reflow soldering process, preventing the 40-position triple-row strip from shifting under the 2.54 mm pitch footprint. This mechanical pre-attachment reduces solder joint defects and tombstoning risk in automated SMT assembly, especially on larger, heavier connector housings.
In which embedded and industrial applications is the 40-position TSM-120-03-SM-DH-P-TR most commonly used?
The TSM-120-03-SM-DH-P-TR is most commonly used in industrial fieldbus interface cards, programmable controller I/O modules, and embedded single-board computers requiring 40-position triple-row SMT connections at 2.54 mm pitch. Its shrouded dual-height housing also makes it suitable for field-replaceable module designs where guided mating reduces assembly errors.
What RoHS and lifecycle status should procurement teams expect when sourcing the TSM-120-03-SM-DH-P-TR?
The TSM-120-03-SM-DH-P-TR is an active, RoHS-compliant product in SAMTEC's TSM surface mount terminal strip family, offering lead-free terminations for environmentally regulated supply chains. Its active status and tape-and-reel packaging make it straightforward to source through standard distributor channels for production quantities requiring 40-position 2.54 mm pitch connectors.
