What are the key features of TSM-123-04-L-DH-P-TR?
- 46-position single-row configuration at 0.100" (2.54 mm) pitch for standard PCB interconnects
- Low-profile (L) termination style minimizes above-board height for space-constrained designs
- Dual-height polarized shroud (DH-P) enforces correct mating orientation across all 46 pins
- Tape-and-reel (TR) packaging optimized for automated SMT pick-and-place production lines
- Surface-mount termination supports reflow solder processing in standard SMT assembly flows
What is TSM-123-04-L-DH-P-TR used for?
SAMTEC TSM-123-04-L-DH-P-TR is suited for embedded systems, industrial I/O boards, and modular PCB assemblies requiring a 46-position polarized surface-mount connector at the standard 0.100-inch pitch. The low-profile shroud and tape-and-reel format make this connector a practical choice for compact, high-volume SMT production where connector orientation errors must be eliminated by design.

Frequently Asked Questions
What does the low-profile designation on TSM-123-04-L-DH-P-TR mean for PCB design clearance?
The -L suffix on TSM-123-04-L-DH-P-TR indicates a low-profile termination style that reduces the above-board connector height compared to standard TSM variants. This gives designers extra clearance for overlying components or housings in 46-pin SMT layouts with tight vertical space budgets.
How does the polarized shroud on TSM-123-04-L-DH-P-TR prevent connector misalignment during assembly?
The dual-height polarized shroud (DH-P) uses an asymmetric mechanical key that prevents the mating header from being inserted in the wrong orientation. This eliminates the risk of reversing the 46-pin signal map and protects PCB circuitry from damage during both assembly and field replacement.
Can TSM-123-04-L-DH-P-TR handle automated high-speed production without manual insertion steps?
Yes. The tape-and-reel (TR) format allows the 46-position TSM-123-04-L-DH-P-TR to be placed directly by SMT pick-and-place machines at standard 0.100-inch pitch, and its SMT solder tails are compatible with lead-free reflow ovens, eliminating manual connector insertion steps.
What is the recommended mating connector for TSM-123-04-L-DH-P-TR, and is it available in matching quantities?
SAMTEC TSM series mating headers at 0.100-inch pitch with a 46-position single-row configuration are the recommended mates for TSM-123-04-L-DH-P-TR. Buyers should specify the required stack height and shroud type when sourcing through SAMTEC's distribution network to ensure a complete connector pair.
