What are the key features of TSM-128-03-SS-DH-P-TR?

  • 56-position single-sided (SS) dual-height (DH) SMT terminal strip at 0.100" (2.54 mm) pitch, offering reliable one-sided signal or mixed power-signal connectivity
  • Polarized (P) keying prevents incorrect connector mating orientation, reducing assembly errors in systems with 56 contacts at 2.54 mm pitch
  • Tape-and-reel (TR) delivery format compatible with automated pick-and-place SMT manufacturing lines for efficient high-volume production

What is TSM-128-03-SS-DH-P-TR used for?

The TSM-128-03-SS-DH-P-TR is used in embedded industrial controllers, communications backplanes, and test-and-measurement boards requiring a 56-position polarized dual-height SMT terminal strip at 0.100" pitch. Its single-sided contact configuration and polarized keying simplify interface design in systems where board-to-board mating orientation is critical.

Frequently Asked Questions

What role does the SS (single-sided) designation play in the TSM-128-03-SS-DH-P-TR's performance?

The SS (single-sided) designation means contacts are arranged on one side of the dual-height body, providing 56 signal or power connections at 0.100" (2.54 mm) pitch without opposing contacts. This simplifies the mating interface and PCB routing in applications where unidirectional board interconnection is required.

How does the polarized keying feature of TSM-128-03-SS-DH-P-TR prevent mating errors during assembly?

The P (polarized) feature introduces a physical keying element to the 56-position 0.100" (2.54 mm) pitch dual-height body, ensuring the connector seats in only one correct orientation. This eliminates mismatched pin assignments, preventing potential short circuits or signal errors caused by reversed mating in automated or manual assembly.

How does TSM-128-03-SS-DH-P-TR compare to TSM-130-02-STL-DH-P-TR for a 56-vs-60-position design choice?

Both share the 0.100" (2.54 mm) pitch and polarized dual-height SMT body; the TSM-128 provides 56 contacts while the TSM-130 offers 60. If the interface protocol requires fewer than 60 signals, the TSM-128-03-SS-DH-P-TR avoids unused pins and may offer a marginally smaller PCB footprint for the terminal strip area.
