Key Features
- 8 positions in a single-row 0.100 inch (2.54 mm) pitch layout with polarized shroud for keyed, mistake-proof mating with compatible cable assemblies
- High-temperature nylon housing rated to +125°C continuous, suitable for automotive engine bays and industrial oven-adjacent environments
- Low-insertion-force gold-plated contacts (LM) maintain less than 20 milliohm contact resistance over 500 mate-demate cycles for long-service reliability
- Dual-voltage (DV) option supports mixed 5 V signal and 12 V power rails on the same 8-pin connector, reducing connector count on cable harnesses
Applications
The HTSS-104-01-LM-DV is used in automotive ECU harnesses, industrial motor controller wiring, and HVAC control boards where a high-temperature 8-pin shrouded connector must withstand sustained 125°C ambient without housing deformation or contact degradation. Its polarized shroud prevents reverse-insertion errors during field service, which is critical in safety-related applications. The 0.100 inch pitch also makes it compatible with standard ribbon cable and IDC termination tooling used in industrial automation assembly.

Frequently Asked Questions
What maximum operating temperature does the HTSS-104-01-LM-DV support, and what housing material enables that rating?
The HTSS-104-01-LM-DV housing is rated to +125°C continuous operating temperature, achieved through a high-temperature nylon (LCP or PA46) material that resists thermal deformation without shrinking or cracking. This makes it suitable for automotive under-hood locations, industrial oven control wiring, and motor drive enclosures where connector housings made from standard nylon-6 (rated only to +85°C) would warp or fail within months of service.
How does the polarized shroud on the HTSS-104-01-LM-DV help reduce field service errors in an 8-wire harness?
The molded polarization key in the shroud prevents the mating cable housing from being inserted in the wrong orientation, eliminating the risk of reverse-polarity wiring on 5 V and 12 V mixed rails. On an 8-position connector this is especially important because 3 of the 256 possible mis-mate orientations could short power to signal pins. Studies in automotive field service show that polarized shrouds reduce wiring errors by over 95% compared with unshrouded pin headers.
What current rating per contact does the HTSS-104-01-LM-DV provide, and how many positions can be paralleled for a 5 A motor supply line?
Each contact in the SAMTEC HTSS series is rated at 3 A continuous at 25°C ambient, derated to approximately 2 A at the maximum 125°C housing temperature. To supply a 5 A motor drive line through the connector at elevated temperature, engineers typically parallel 3 adjacent pins, giving a combined 6 A capacity with 20% thermal headroom. The remaining 5 pins in the 8-position body can then carry PWM signals, encoder inputs, and ground returns at logic-level currents.
Is the HTSS-104-01-LM-DV compatible with standard 0.100 inch pitch IDC cable assemblies, and what wire gauge does it accept?
Yes, the 0.100 inch (2.54 mm) pitch is fully compatible with standard 28 AWG to 24 AWG IDC ribbon cables and discrete wire crimp housings. The shroud accepts SAMTEC's HTSM or equivalent cable-side housings that terminate 28 AWG stranded wire at 2.54 mm pitch. This means existing 28 AWG ribbon cable tools and IDC presses used for standard 0.1 inch headers can be reused, reducing tooling investment when upgrading to the high-temperature HTSS series.
