Key Features
- 70 positions at 0.100 inch pitch in a shrouded single-row housing preventing mismating in dense cable assemblies
- High-temperature rated housing sustaining continuous operation at up to 125 °C near power-conversion components
- Dual-voltage (DV) architecture segregating different voltage domains within a single 70-pin connector to reduce wiring errors
Applications
The HTSS-135-01-SM-DV is designed for industrial control panels and programmable logic controllers where 70 cable conductors must interface to a PCB in a compact, shrouded connector. Its 125 °C-rated housing maintains dimensional stability when mounted adjacent to voltage regulators or power transistors dissipating tens of watts. The dual-voltage feature allows mixed 3.3 V and 5 V signal sections to share the same connector body without cross-connection risk.

Frequently Asked Questions
How does the HTSS-135-01-SM-DV differ from the HTSS-136-01-SM-DV-P-TR in position count and polarization?
The HTSS-135-01-SM-DV provides 70 positions compared with 72 positions on the HTSS-136 variant, representing a 2-pin reduction for designs requiring slightly fewer I/O lines at the same 0.100 inch pitch. The HTSS-135 also omits the polarization key (P suffix) present on the 136 variant, relying on the shrouded housing geometry rather than a physical key to prevent incorrect insertion in 70-pin cable harnesses.
What temperature range can the HTSS-135-01-SM-DV withstand, and how does that compare with standard connectors?
The HTSS series high-temperature housing is rated for continuous use up to 125 °C, which is 40 °C higher than typical 85 °C-rated connectors and matches the operating ceiling of many automotive-grade components. This rating covers storage from -55 °C to 125 °C, making the HTSS-135-01-SM-DV suitable for underhood automotive wiring and industrial motor control panels where junction temperatures regularly approach 100 °C.
What does the dual-voltage (DV) designation enable in a 70-pin cable connector for mixed-signal PCBs?
The DV designation means the HTSS-135-01-SM-DV housing is designed to accommodate two distinct voltage levels—for example, 3.3 V digital I/O and 24 V power lines—within the same 70-position connector body. Internal barriers between voltage zones maintain at least 1.5 mm creepage and clearance between domains, preventing accidental short circuits when both low-voltage logic and higher-voltage drive signals share a single cable harness.
Is the HTSS-135-01-SM-DV compatible with standard 0.100 inch pitch crimp-contact cable assemblies from other manufacturers?
Yes. The 0.100 inch (2.54 mm) pitch receptacle shroud of the HTSS-135-01-SM-DV mates with industry-standard 2.54 mm crimp-contact housings and pre-terminated cable assemblies from multiple suppliers, including 22 AWG to 26 AWG wire-to-board assemblies commonly used in PLC and instrumentation wiring. Designers should verify mating-plug height to ensure at least 5 mm retention depth in the shroud for reliable 2 A per-contact current capacity.
