Frequently Asked Questions
How many positions and what contact pitch does the HTSS-121-01-H-DV terminal strip provide?
The HTSS-121-01-H-DV provides 42 positions with 0.100 inch (2.54 mm) pitch between contacts arranged in a dual-row rectangular pattern. The 2.25 inch body length and 0.365 inch breadth house male square-pin contacts, accepting standard 0.100 inch pitch cable mates commonly used in industrial control wiring harnesses rated above 85°C.
What mechanical advantage does the polarized shroud of the HTSS-121-01-H-DV offer in dense industrial wiring environments?
The polarized shroud on the HTSS-121-01-H-DV ensures that all 42 contacts align correctly during cable mating, preventing pin-shift errors that can occur in dense wiring environments with multiple identical connectors installed side by side. This polarization reduces field service errors in PLC I/O assemblies and motor drive panels operating at temperatures up to 105°C with hundreds of reconnection cycles.
When would an engineer select the HTSS-121-01-H-DV over a standard non-shrouded header for a 42-pin cable interface?
An engineer would select the HTSS-121-01-H-DV when the 42-pin cable must be field-mated in low-visibility or high-vibration conditions, since the shroud provides physical guidance for correct 0.100 inch pitch alignment and the high-temperature rating ensures performance above 85°C. A non-shrouded header requires visual pin alignment and offers no mechanical protection against lateral cable forces, increasing field fault risk in industrial panel installations.
