Key Features
- 58 positions in dual-row (DH) layout at 0.100 inch (2.54 mm) pitch
- Top-mount (TM) termination style for flush component placement on PCB surface
- Polarized (P) contact design prevents reversed mating on 58-position dual-row interface
- Tape-and-reel (TR) packaging compatible with automated SMT pick-and-place equipment
- A-coded alignment feature for secure and repeatable board-to-board mating
- Standard 0.100 inch pitch ensures compatibility with common PCB EDA library footprints
Applications
The TSM-129-01-TM-DH-A-P-TR is suited for 58-signal board-to-board interconnect in embedded computing daughter cards, industrial I/O modules, communications expansion boards, and test equipment rear panels. Its 0.100 inch pitch dual-row layout supports routing of power and signal lines within standard PCB design rules, while the top-mount style minimizes the connector profile above the board surface. Tape-and-reel packaging makes it ready for automated volume SMT assembly.

Frequently Asked Questions
What termination style does the TSM-129-01-TM-DH-A-P-TR use, and how does it affect PCB clearance?
The TSM-129-01-TM-DH-A-P-TR uses a top-mount (TM) termination style where the contact tails fold onto the top surface of the PCB pads, eliminating the need for through-board clearance and allowing component placement on the opposite side of the board beneath the 58-position connector.
How does polarization (P) protect a 58-position dual-row SMT connection from assembly errors?
The P polarization feature physically keys the mating interface so the 58-position dual-row connector can only engage in the correct orientation, preventing the reversed insertion that would swap signal and power pins on a 0.100 inch pitch board and risk damaging connected logic or power circuits.
Which board-to-board applications typically require a 58-position 0.100 inch pitch terminal strip?
Embedded single-board computer stacking connectors, industrial digital I/O expansion modules, communications protocol daughter cards, and automated test equipment interface boards commonly use 58-position 0.100 inch dual-row terminal strips for signal and power distribution across 29 pairs of contacts.
Is the tape-and-reel format of TSM-129-01-TM-DH-A-P-TR compatible with standard SMT feeder widths?
Yes, SAMTEC TSM-series tape-and-reel parts use industry-standard carrier tape widths compatible with common SMT line feeders, so the 58-position TSM-129-01-TM-DH-A-P-TR can be loaded directly into existing pick-and-place equipment without special tooling changes.
