Key Features
- 46-position dual-row terminal strip at 0.100 inch (2.54 mm) pitch providing 46 contacts in a compact SMT footprint
- Through-hole tail (T) contact style for mixed SMT and through-hole board attachment options
- Tape-and-reel (TR) packaging enabling automated pick-and-place assembly for high-volume production runs
Applications
The TSM-123-04-T-DH-A-K-TR suits applications requiring 46 connections across a dual-row 2.54 mm pitch terminal strip, such as embedded computing interfaces, test and measurement boards, and industrial control backplanes. Its through-hole tail variant provides additional mechanical retention compared to standard SMT-only footprints, making it useful where board vibration or stress is a concern. Tape-and-reel packaging supports scalable automated assembly workflows.

Frequently Asked Questions
What contact style does the TSM-123-04-T-DH-A-K-TR use and how does it affect PCB mounting?
The TSM-123-04-T-DH-A-K-TR uses a through-hole tail (T) contact style, which means the connector pins pass through PCB vias for additional mechanical anchoring beyond standard SMT pads. This provides stronger retention — important in applications with vibration or mechanical stress — while maintaining the 2.54 mm pitch and 46-position dual-row layout.
How does the 46-position count of TSM-123-04-T-DH-A-K-TR compare to related SAMTEC TSM variants?
Within the SAMTEC TSM series at 0.100 inch (2.54 mm) pitch, the 46-position TSM-123-04-T-DH-A-K-TR sits between smaller 26-position and larger 52-position or 68-position dual-row variants. Selecting 46 positions allows designers to allocate signals for 23 pairs or a 46-bit parallel bus in a dual-row configuration without the extra length of a 52-pin or 68-pin strip.
For which production environments is the TSM-123-04-T-DH-A-K-TR packaging format most suitable?
Tape-and-reel (TR) packaging on the TSM-123-04-T-DH-A-K-TR is optimized for automated SMT pick-and-place lines, making it most suitable for medium to high-volume manufacturing. Facilities running reel-fed assembly equipment benefit from reduced component handling time compared to loose or tube-packaged alternatives for a 46-position dual-row connector.
