Key Features
- 34 positions in dual-row SMT layout on 0.100" (2.54 mm) pitch for reliable high-count signal interconnect
- Polarization (P) key preventing incorrect mating orientation and reducing assembly defects on multi-connector boards
- Dual-height (DH) body providing flexibility to mate with different stack-height headers without PCB redesign
- SMT termination enabling fully automated reflow soldering without through-hole drilling requirements
- Tape-and-reel (TR) packaging for continuous automated pick-and-place production line feeding
Applications
The TSM-117-02-SM-DH-P-TR is used in industrial automation controllers, embedded computing modules, and communications switching boards where 34-position dual-row SMT connectors are needed with polarization to prevent assembly errors. Its dual-height compatibility provides system designers flexibility when stacking PCBs at different board-to-board spacings. Tape-and-reel delivery minimizes handling interruptions during high-volume SMT production runs.

Frequently Asked Questions
How does the polarization feature of TSM-117-02-SM-DH-P-TR prevent costly assembly errors on boards with multiple similar connectors?
The polarization (P) key on TSM-117-02-SM-DH-P-TR creates a mechanical asymmetry that blocks the mating connector from being inserted backwards across all 34 positions on the 0.100 inch pitch dual-row footprint. This eliminates the risk of reversed connections during both automated and manual assembly, preventing damage to ICs and signal integrity issues.
What does the SM designation specify about how TSM-117-02-SM-DH-P-TR is soldered to a PCB, and is wave soldering supported?
The SM designation indicates surface-mount termination, meaning TSM-117-02-SM-DH-P-TR is designed for reflow soldering to SMT pads rather than wave soldering through holes. Lead-free reflow profiles up to 260°C peak temperature are supported, and all 34 positions are placed coplanarly to ensure uniform pad contact during the reflow process.
When would a designer choose TSM-117-02-SM-DH-P-TR over a non-polarized 34-position dual-row strip in a high-mix production environment?
In high-mix SMT production where multiple 34-position 0.100 inch pitch connectors populate the same board, the polarization feature of TSM-117-02-SM-DH-P-TR enforces correct orientation at the connector body level, eliminating dependence on operator visual inspection. This reduces rework rates and quality escapes, particularly when assemblers handle many different board variants in a single shift.
Is TSM-117-02-SM-DH-P-TR available in a packaging format compatible with automated SMT assembly lines, and what reel quantities are typical?
Yes, the -TR suffix confirms tape-and-reel packaging, meaning TSM-117-02-SM-DH-P-TR is delivered on standard reels compatible with automated SMT feeders. Tape-and-reel format typically ships in quantities of 250 to 1000 pieces per reel for a 34-position connector at 0.100 inch pitch, enabling uninterrupted high-volume production without manual loader intervention.
