What are the key features of TSM-129-03-S-DH-A-P-TR?
- 58-position dual-row SMT terminal strip at 0.100" pitch provides 29 contacts per row for high signal count board-to-board interconnect
- Shrouded (S) housing with polarization peg (P) prevents misalignment and accidental reversal across all 58 positions
- Tape-and-reel (TR) format enables high-speed automated pick-and-place assembly with consistent component orientation
What is TSM-129-03-S-DH-A-P-TR used for?
The TSM-129-03-S-DH-A-P-TR is designed for high-density board-to-board signal routing in embedded computing, telecommunications, and industrial control systems requiring 58 simultaneous connections at 0.100-inch pitch. The shrouded and polarized design protects contacts during mating and prevents misconnection in field-serviceable modules or backplane-mounted cards. Tape-and-reel packaging ensures compatibility with standard SMT pick-and-place equipment for efficient high-volume board assembly.

Frequently Asked Questions
What is the contact arrangement of the TSM-129-03-S-DH-A-P-TR and how much PCB length does it occupy?
The TSM-129-03-S-DH-A-P-TR uses a dual-row configuration with 29 contacts per row at 0.100-inch pitch, totaling 58 positions and occupying approximately 2.9 inches of PCB board edge. This makes it suitable for mid-size embedded processor modules, FPGA development boards, and industrial I/O expansion cards needing a high-density shrouded SMT interface.
How does the shroud on the TSM-129-03-S-DH-A-P-TR protect contacts during module insertion in a rack-mount system?
The shrouded (S suffix) housing on the TSM-129-03-S-DH-A-P-TR surrounds all 58 contact pins, guiding the mating connector and shielding pins from physical damage during blind-mating in rack-mount or chassis applications. Combined with the polarization peg, the shroud ensures single-orientation insertion, which is essential for differential pair integrity on high-speed 0.100-inch pitch interfaces operating above 1 Gbps.
Is the TSM-129-03-S-DH-A-P-TR a suitable upgrade from an unkeyed 58-position strip in a design with frequent connector cycling?
Yes. Replacing an unkeyed 58-position terminal strip with the TSM-129-03-S-DH-A-P-TR adds a polarization peg and shroud that prevent misinsertion damage during the expected connector mating lifetime, typically rated at 30 or more insertion cycles. For service-accessible modules or test fixtures cycled more than 25 times per year, this keyed shrouded design significantly reduces connector damage and field repair costs compared to unprotected alternatives on 0.100-inch pitch boards.
