What are the key features of HTSS-127-01-SM-DV?
- 54-position single-row layout at 0.100-inch (2.54 mm) pitch accommodates standard IDC ribbon cable assemblies for dense signal routing
- High-temperature shroud construction tolerates elevated ambient conditions during automated reflow soldering and in-service operation
- Polarizing shroud prevents incorrect cable insertion, reducing field wiring errors in multi-connector panel assemblies
- Surface-mount (SM) footprint with dual-via (DV) anchor posts combines SMT assembly efficiency with through-hole mechanical retention strength
What is HTSS-127-01-SM-DV used for?
The HTSS-127-01-SM-DV is used in industrial control panels, embedded computing backplanes, and test instrumentation where 54 digital or analog signals must transition from a PCB header to a routed ribbon cable harness. Its high-temperature shroud maintains contact alignment at reflow temperatures up to 260°C, enabling pick-and-place assembly on standard SMT production lines. Engineers in robotics, PLC expansion modules, and aerospace ground support equipment choose this connector when both reliable cable mating and high-density signal consolidation on a 0.100-inch pitch are required.

Frequently Asked Questions
How many positions does HTSS-127-01-SM-DV carry and what pitch spacing is used for cable mating?
HTSS-127-01-SM-DV provides 54 positions in a single-row configuration at 0.100-inch (2.54 mm) pitch. This matches standard 54-conductor IDC ribbon cable assemblies, making it directly compatible with flat cables terminated using industry-standard IDC tooling without requiring custom cable assemblies or pitch adapters.
In a high-temperature PCB assembly process, what maximum temperature can the HTSS-127-01-SM-DV shroud withstand during reflow?
The high-temperature shroud on HTSS-127-01-SM-DV is rated to withstand standard SMT reflow profiles peaking at 260°C for up to 30 seconds, in compliance with IPC/JEDEC J-STD-020 reflow guidelines. This allows the connector to be placed alongside other SMD components on the same reflow pass without warping or deformation that would compromise the 0.100-inch pitch contact alignment.
How does the dual-via (DV) anchor post design of HTSS-127-01-SM-DV improve mechanical retention compared to a standard SMT header?
The dual-via anchor posts insert through 2 PTH holes in the PCB and are soldered from the back side, providing resistance to cable pull-out forces perpendicular and parallel to the board surface. Samtec specifies the combined pull strength of anchor posts plus SMT pads at greater than 50 N in-plane shear, approximately 3x the retention of SMT-only headers, making this configuration suitable for hand-mated cable connections that undergo repeated plug/unplug cycles.
For a 54-signal PLC expansion module, is HTSS-127-01-SM-DV interchangeable with a standard HTSS-127-01-L-DV through-hole variant?
HTSS-127-01-SM-DV uses surface-mount solder tails with dual-via anchor posts, while HTSS-127-01-L-DV (Long version) uses through-hole tails that extend 6.35 mm below the PCB surface for wave soldering. Both carry 54 positions at 0.100-inch pitch and share the same mating cable footprint, so the cable assembly is interchangeable. However, the PCB land patterns differ: SM requires SMD pads plus 2 anchor holes, whereas the L variant requires 54 through-holes, so PCB layouts are not directly swappable between the two variants.
