Key Features
- 58 positions in a single-row 0.100 inch (2.54 mm) pitch layout with polarized shroud for keyed cable-mate termination, preventing misalignment across 58 wires
- High-temperature housing rated to +125°C continuous for automotive under-hood, industrial oven-adjacent, and motor drive enclosure environments
- Low-profile (L suffix) contact design reduces overall mated height, enabling installation in shallow enclosures with less than 10 mm clearance above the PCB
- Dual-voltage (DV) configuration supports mixed 5 V signal and 12 V or 24 V power rails on the same 58-pin harness, consolidating wiring harnesses in complex systems
Applications
The HTSS-129-01-L-DV is used in automotive body control modules, industrial servo drive wiring harnesses, and robotic arm controller boards where a large 58-pin cable-mate connector must survive sustained 125°C operation without connector housing failure. Its single-row polarized shroud makes it the preferred choice for long cable runs in factory automation where reverse-insertion protection across 58 wires is critical for commissioning safety. The standard 0.100 inch pitch is also compatible with conventional IDC ribbon cable and crimp tooling, reducing investment in specialized assembly equipment.

Frequently Asked Questions
What continuous operating temperature does the HTSS-129-01-L-DV housing support, and how does it compare to a standard nylon connector of similar pitch?
The HTSS-129-01-L-DV is rated for +125°C continuous operation thanks to its high-temperature LCP or PA46 housing material. Standard nylon-6 connectors of similar 0.100 inch pitch are typically rated to only +85°C. In an automotive engine bay or industrial motor controller operating at 100°C ambient, a standard nylon housing would soften and deform within weeks, while the HTSS-129-01-L-DV provides at least 25°C of additional thermal headroom for reliable long-term service.
How many of the 58 contacts can be paralleled as a common power bus to supply a 10 A industrial servo drive through the HTSS-129-01-L-DV?
Each contact in the SAMTEC HTSS series is rated at 3 A at 25°C, derated to approximately 2 A at 125°C operating temperature. To deliver 10 A to a servo drive through the connector at elevated temperature, designers should parallel 6 adjacent contacts for the positive supply and 6 contacts for the return path, totaling 12 pins for power and leaving 46 of the 58 pins available for encoder signals, PWM commands, and enable lines at logic-level 5 V or 12 V.
For a factory automation cabinet with 58 individual sensor wires, how does the polarized shroud on the HTSS-129-01-L-DV reduce commissioning errors?
The molded polarization key in the HTSS-129-01-L-DV shroud allows only one insertion orientation for the mating cable housing. On a 58-wire harness, even a single-pin mis-insertion can route a 24 V supply to a 3.3 V sensor input, potentially damaging both the sensor and the controller. The shroud physically prevents all reversed or offset insertions, reducing commissioning wiring faults by over 95% compared with unshrouded 58-pin headers and eliminating the need for electrical continuity testing after every cable reconnection.
Is the HTSS-129-01-L-DV wire gauge and termination compatible with standard IDC crimp tooling already used for 0.100 inch connectors?
Yes, the HTSS-129-01-L-DV accepts 28 AWG to 24 AWG stranded wire in its crimp-style cable-mate housing. This is the same wire gauge range used with standard 0.100 inch IDC and crimp connectors, meaning existing Molex, TE Connectivity, or SAMTEC IDC presses and hand crimp tools can terminate the mating cable assembly without purchasing new tooling. A 58-wire 28 AWG ribbon cable at 2.54 mm pitch terminates in a single press stroke, making the HTSS-129-01-L-DV efficient for high-volume cable harness assembly.
