Key Features
- 68-position dual-row layout with 0.100" (2.54 mm) pitch provides 34 contacts per row for high-density parallel bus interconnect
- Stainless steel (SS) contacts deliver superior corrosion resistance and mechanical durability for harsh or humid environments
- Tape-and-reel (TR) packaging supports fully automated SMT pick-and-place assembly on high-volume production lines
Applications
The TSM-134-04-SS-DH-A-K-TR is used in backplane interconnect assemblies, industrial control cards, and rack-mounted network equipment requiring high-density, corrosion-resistant dual-row connectors. Its 68-position configuration handles 64-bit parallel buses plus ancillary signal lines on a single connector. The stainless steel contact variant is preferred in environments with elevated humidity, condensation, or mild chemical exposure where standard brass contacts may corrode over time.

Frequently Asked Questions
How does the TSM-134-04-SS-DH-A-K-TR differ from the TSM-134-04-STL-DH-A-K-TR in contact construction?
The TSM-134-04-SS-DH-A-K-TR uses stainless steel (SS) contacts, while the STL variant also specifies stainless steel contacts with a specific plating designation. Both provide corrosion-resistant contacts for harsh environments, but designers should consult the SAMTEC datasheets to confirm exact plating thickness and contact resistance specifications, which may vary between the two suffix options across 68 positions at 0.100" pitch.
What bus width does the 68-position TSM-134-04-SS-DH-A-K-TR support in a dual-row backplane interconnect?
With 68 total positions in 2 rows at 0.100" pitch, the TSM-134-04-SS-DH-A-K-TR can carry a 64-bit wide data bus plus 4 signals for address, power, or control lines. This makes it suitable for 64-bit processor buses, wide memory interfaces, or dual 32-bit buses sharing a single backplane connector on industrial and telecom PCBs.
For a sealed industrial enclosure with humidity above 85% RH, why would TSM-134-04-SS-DH-A-K-TR be chosen over a standard brass contact connector?
At humidity levels above 85% RH, standard brass contacts can develop an oxide layer that increases contact resistance from a few milliohms to tens of milliohms over time, degrading signal integrity. Stainless steel contacts in TSM-134-04-SS-DH-A-K-TR resist oxidation and corrosion without surface treatment degradation, maintaining stable contact resistance across the 68 positions over years of operation in humid industrial enclosures.
How does tape-and-reel (TR) packaging of TSM-134-04-SS-DH-A-K-TR support high-volume SMT manufacturing?
The TSM-134-04-SS-DH-A-K-TR is packaged in tape-and-reel format, allowing direct loading into standard SMT pick-and-place machine feeders typically using 12 mm or wider carrier tape. The embossed tape maintains consistent orientation and spacing of each 68-position dual-row connector, enabling accurate automated placement on PCB pads at the 0.100" pitch and reducing per-unit assembly cycle time in high-volume production runs.
