Key Features
- 18-position dual-row configuration at 0.100 inch (2.54mm) pitch provides 18 signal contacts in a compact 22.5mm wide shrouded body for space-constrained PCB layouts
- High-temperature shroud thermoplastic maintains dimensional accuracy and contact retention at continuous operating temperatures up to at least 105°C for demanding thermal environments
- Polarized shroud key prevents 18-pin cable harness mis-mating, protecting signal and power lines from incorrect orientation during maintenance and field installation
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly for high-volume production runs with consistent connector placement accuracy
- SAMTEC SS-series surface-mount termination style provides low-profile PCB attachment with solder joint integrity suited for automated reflow at 245°C to 260°C peak temperature
Applications
The HTSS-109-01-SS-DV-P-TR suits 18-signal cable-to-board interfaces on compact industrial sensor modules, embedded controller boards, and test fixture daughtercards that require a polarized high-temperature shrouded connector in a small footprint. Its 0.100 inch pitch and dual-row 18-position layout provides a standardized mating interface for ribbon cable or discrete wire harnesses used in PLC I/O modules, motor encoder interfaces, and field instrument calibration ports. The tape-and-reel SMT format enables efficient automated assembly in high-volume production of IoT gateways, HVAC controllers, and building automation terminal units.

Frequently Asked Questions
How many signal positions does the HTSS-109-01-SS-DV-P-TR have, and how does the dual-row arrangement benefit PCB layout?
The HTSS-109-01-SS-DV-P-TR has 18 positions in a dual-row (DV) layout with 9 pins per row at 0.100 inch (2.54mm) pitch, giving a connector body length of approximately 22.5mm across the 9-position row. The dual-row arrangement at 2.54mm pitch allows 18 signals to be routed through a connector footprint that is roughly half the length of a single-row 18-pin connector, which saves PCB edge space and enables the cable harness to exit perpendicular to the board without a long single-row connector extending to the board edge.
What is the temperature capability of the HTSS-109-01-SS-DV-P-TR shroud, and how does it compare to standard nylon connectors?
The HTSS-109-01-SS-DV-P-TR uses a high-temperature thermoplastic shroud rated for continuous operation at temperatures up to at least 105°C, compared to standard PA66 nylon connectors that are typically rated only to 85°C continuous. This 20°C to 25°C additional thermal margin is significant in industrial enclosures near power electronics where local PCB temperatures regularly reach 90°C to 100°C. The high-temperature material also survives standard SMT reflow profiles at 245°C to 260°C peak temperature without shroud distortion or pin pitch shift, which standard connectors may not tolerate reliably.
How does the polarization feature of the HTSS-109-01-SS-DV-P-TR reduce installation errors on 18-pin cable harnesses?
The polarized shroud on the HTSS-109-01-SS-DV-P-TR includes a molded key that mates only with the correctly oriented cable-mate housing, preventing the 18-pin connector from being inserted rotated 180 degrees or shifted by one row. On an 18-pin dual-row connector, a half-pitch mis-insertion would cross-connect all 18 signals to the wrong board nets, which at 3.3V or 5V logic levels could damage ICs on both the cable and PCB ends simultaneously. The polarization key eliminates this failure mode without requiring the technician to verify pin-1 orientation against a reference label during field service.
For automated SMT assembly, how does tape-and-reel packaging affect placement accuracy of the HTSS-109-01-SS-DV-P-TR?
Tape-and-reel (TR) packaging for the HTSS-109-01-SS-DV-P-TR orients each connector consistently in the tape pocket so that pin 1 is always in the same position relative to the tape feed direction. Modern pick-and-place machines achieve placement accuracy of ±0.05mm to ±0.1mm for SMT components in tape-and-reel, which is well within the 2.54mm pin pitch tolerance for reliable solder paste registration on the 18-pin SMT footprint. Consistent tape orientation also eliminates the manual orientation step required for bulk-packed connectors, reducing placement cycle time by approximately 2 to 5 seconds per connector on semi-automated lines.
Which cable assemblies mate with the HTSS-109-01-SS-DV-P-TR, and what conductor gauges are compatible?
The HTSS-109-01-SS-DV-P-TR mates with SAMTEC HTSD-109 and HTSL-109 series 18-position cable assemblies at 0.100 inch (2.54mm) pitch, available in IDC ribbon cable or discrete wire termination styles. Compatible conductor gauges for IDC ribbon cable mating range from 26 AWG to 30 AWG, supporting per-pin current ratings from 1A to 3A depending on conductor cross-section. Discrete wire harnesses using 24 AWG conductors at 2.54mm pitch connectors can carry up to 3A per pin, making the 18-position interface capable of delivering up to 54A total harness current when all pins are loaded for mixed power and signal assignments.
