Key Features
- 70-position dual-row layout on 0.100" (2.54 mm) pitch for high-density board-to-cable connectivity
- Stainless-steel (SS) contact plating provides superior corrosion and oxidation resistance in harsh environments
- High-temperature housing rated to 105 °C sustains contact retention in thermally stressed industrial assemblies
- Shrouded keyed body prevents 180-degree mismating across all 70 positions, protecting complex harnesses
- Through-hole DV (dual-row vertical) mounting configuration enables secure PCB anchoring without tape-and-reel limitations
Applications
The HTSS-135-01-SS-DV is suited for industrial automation boards, marine electronics, and outdoor instrumentation enclosures where 70-pin board-to-cable connectors must resist corrosion from humidity, salt spray, or industrial chemicals. Its stainless-steel contacts and high-temperature housing make it a reliable choice for motor-control backplanes, process-control field devices, and military-grade ancillary boards requiring long-term connection integrity in aggressive environments.

Frequently Asked Questions
What distinguishes the stainless-steel (SS) contact plating of the HTSS-135-01-SS-DV from standard tin or gold options for corrosive environments?
Stainless-steel contact plating resists oxidation and corrosion far better than tin at equivalent cost, maintaining stable contact resistance below 30 milliohms even after prolonged exposure to salt spray, industrial solvents, or high-humidity environments exceeding 85% relative humidity. Gold offers even lower resistance but at a significantly higher material cost, making SS the preferred balance of corrosion immunity and price for connectors on outdoor or marine electronics boards.
For a 70-position harness on a motor-control backplane, how does the shroud of the HTSS-135-01-SS-DV prevent damage during field maintenance?
The shrouded housing physically constrains the mating cable connector so it can only insert in the correct orientation. On a 70-pin dual-row strip, reversing the cable would invert all 70 signal and power lines simultaneously, potentially destroying motor-drive ICs or corrupting encoder feedback. The shroud eliminates that failure mode at zero additional wiring cost and requires no procedural reminder in the maintenance manual.
How does the non-tape-and-reel packaging of the HTSS-135-01-SS-DV (no TR suffix) affect procurement and assembly planning?
Without the TR suffix, the HTSS-135-01-SS-DV ships in tray or tube packaging rather than tape-and-reel. This suits low-to-medium production volumes where manual placement or semi-automated insertion is used. Tray packaging typically comes in quantities of 50 to 200 pieces per tray, which simplifies inventory management for prototyping or production runs under 1,000 boards per month without requiring dedicated SMT reel feeders.
Which SAMTEC cable assemblies mate with the HTSS-135-01-SS-DV, and at what operating temperature should the full cable assembly be derated?
The HTSS-135-01-SS-DV is designed to mate with SAMTEC HTSM series cable assemblies, which share the same 70-position 0.100 inch pitch keyed interface. The HTSS housing is rated to 105 °C continuous, but cable assemblies using PVC wire jackets should be derated to 80 °C to prevent jacket softening. For full 105 °C system operation, SAMTEC recommends pairing with HTSM cable assemblies using PTFE or silicone wire jackets rated to 150 °C or higher.
