What are the key features of HTSS-121-01-SS-DV-P-TR?
- 42 dual-row contacts on 2.54 mm pitch provide high-density cable-to-board wiring in a single polarized shrouded housing
- High-temperature rating from -55°C to 105°C enables deployment in industrial motor-drive enclosures and thermally stressed environments
- Stainless-steel (SS) hardware variant offers superior corrosion resistance over standard hardware in humid or chemically aggressive environments
- Tape-and-reel (TR) packaging with standard 24 mm carrier tape enables automated pick-and-place assembly in high-volume SMT production
What is HTSS-121-01-SS-DV-P-TR used for?
The HTSS-121-01-SS-DV-P-TR is used in industrial wiring harnesses for programmable logic controllers, servo drive controllers, and power distribution panels where 42 reliable cable-to-board connections must withstand continuous temperatures up to 105°C. The stainless-steel hardware option makes it particularly suitable for food-processing equipment, marine electronics, and outdoor enclosures exposed to moisture, salt spray, or cleaning chemicals that would corrode standard brass hardware over time. Tape-and-reel delivery integrates seamlessly into automated SMT assembly lines building high-volume embedded control boards for HVAC systems and industrial sensors.

Frequently Asked Questions
How many contact positions and what pitch does the HTSS-121-01-SS-DV-P-TR offer for cable harness termination?
The HTSS-121-01-SS-DV-P-TR provides 42 contact positions arranged in 2 rows of 21 contacts each on a 2.54 mm (0.100") pitch, giving a connector body length of approximately 53.3 mm. The dual-row layout doubles contact density versus a single-row strip of the same footprint, enabling 42 individual signal or power lines from a cable assembly to terminate to a PCB in one keyed, shrouded mating action. This pin count suits medium-density I/O expansion headers on embedded controllers and data acquisition cards.
What does the SS suffix indicate on HTSS-121-01-SS-DV-P-TR, and in which environments is it specifically advantageous?
The SS suffix designates stainless-steel hardware for the mounting and latching elements of the HTSS-121 series, replacing the standard brass hardware with a material that resists corrosion in salt-spray environments per ASTM B117, humidity above 90% RH, and exposure to mild acids or alkalis found in food-processing and chemical-plant settings. Brass hardware corrodes within 200 hours of 5% salt-spray exposure at 35°C, whereas stainless steel retains structural integrity beyond 1,000 hours. For marine control panels or outdoor HVAC controllers installed in coastal regions, the SS option prevents hardware seizure that would prevent field connector removal.
What is the maximum continuous operating temperature of the HTSS-121-01-SS-DV-P-TR, and why does it matter for motor-control panels?
The HTSS-121-01-SS-DV-P-TR is rated for continuous operation from -55°C to +105°C, providing a 20°C margin above the 85°C upper limit of standard commercial-grade connectors. Motor-drive control panels that house variable-frequency drives and servo amplifiers can reach internal ambient temperatures of 70°C to 90°C during full-load operation, meaning standard connectors near heat sources operate at or above their rated ceiling. The 105°C-rated thermoplastic housing prevents pin-position shift, mating force degradation, and contact resistance increase that standard connectors exhibit when repeatedly thermally cycled between 25°C and 100°C.
How does HTSS-121-01-SS-DV-P-TR compare to HTSS-127-01-S-DV-P-TR for a 42-position wiring harness application?
Both connectors share the 2.54 mm pitch, 105°C temperature rating, dual-row shrouded housing, and TR tape-and-reel packaging, but the HTSS-121 provides exactly 42 positions versus 54 positions on the HTSS-127. For a wiring harness with 38 to 42 conductors, the HTSS-121 is the correct fit since using the HTSS-127 would leave 12 empty contacts that add unnecessary connector length of approximately 15.2 mm. The HTSS-121-01-SS variant additionally offers stainless-steel hardware absent on the standard HTSS-127-01-S, making the -121 preferable in corrosive environments regardless of pin count.
