Key Features
- 54-position single-row .100" (2.54mm) pitch shrouded terminal strip for polarized high-density cable-to-board interconnects
- High-temperature (HTSS) rated housing sustains reliable operation up to 105°C continuous ambient, suitable for automotive and industrial environments
- Dual-voltage (DV) polarized shroud physically prevents reverse or offset mating, eliminating wiring errors in 54-circuit cable assemblies
- Taller (H) profile shroud provides additional cable strain relief clearance and improved mechanical retention in vibration-prone installations
Applications
The HTSS-127-01-H-DV is designed for cable-to-board connectivity in industrial automation, automotive electronics, and high-temperature embedded computing systems that demand 54-circuit polarized interconnects. Its high-temp rated shroud and dual-voltage polarization make it the connector of choice for motor controllers, PLCs, and multi-axis servo drives operating in environments above 85°C. Engineers use this terminal strip to achieve reliable multi-signal routing with standard 2.54mm cable assemblies in tray-supplied production and field-serviceable equipment.

Frequently Asked Questions
How many circuits does the HTSS-127-01-H-DV support and what is its contact pitch?
The HTSS-127-01-H-DV provides 54 positions in a single-row configuration at a .100" (2.54mm) pitch, accommodating 54 individual circuit connections in one compact connector. This standard 2.54mm pitch is compatible with a wide range of IDC ribbon cable assemblies and discrete wire harnesses, making it a versatile choice for multi-channel signal routing in industrial and automotive PCB designs.
What continuous temperature can the HTSS-127-01-H-DV withstand and why is this important in automotive applications?
The HTSS-127-01-H-DV is rated for continuous operation up to 105°C ambient temperature as indicated by its HTSS (High-Temperature Shrouded Strip) designation. Automotive applications such as engine control units and under-hood sensor interfaces routinely experience ambient temperatures exceeding 85°C. This 105°C rating ensures the 54-position housing and contact springs maintain mechanical integrity, proper retention force, and low contact resistance without thermal creep or housing deformation throughout a 15-year vehicle service life.
How does the dual-voltage (DV) feature protect 54-circuit cable harnesses from mis-mating during field assembly?
The dual-voltage (DV) shroud on the HTSS-127-01-H-DV incorporates a physical polarization key that allows mating in only one correct orientation across all 54 circuits, blocking reverse or transposed connector insertion. In field-service scenarios where technicians replace or reconnect cable harnesses in limited-visibility enclosures, this polarization feature prevents power rail reversals or signal cross-connections that would damage ICs operating at 3.3V to 5V logic levels, reducing service-related circuit failures to near zero.
When would an engineer choose the HTSS-127-01-H-DV (H-profile) over the standard-profile HTSS-127-01-T-DV-P-TR?
The H-profile (tall profile) variant like HTSS-127-01-H-DV is selected when cable bundles exiting the 54-position connector are thick or stiff, requiring additional vertical clearance above the PCB to avoid stressing the cable jacket or connector housing. The taller 'H' shroud provides more cable strain relief clearance typically between 8mm and 12mm above the board surface compared to the 'T' (trim/low) profile, improving long-term connector retention in vibration environments like industrial motor drives and vehicle wiring harnesses.
