What are the key features of HTSS-121-01-LM-DV-P-TR?
- 42-position single-row layout on 0.100 inch (2.54 mm) pitch provides dense cable termination in a compact shrouded strip for mid-range pin-count cable harnesses
- High-temperature housing material withstands sustained operating temperatures up to 105°C, suitable for industrial enclosures and motor drive cable assemblies
- Polarized shroud design prevents reversed cable mating in field installations, reducing wiring errors in 42-way control and signal harnesses
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly for high-volume PCB production with consistent component orientation
What is HTSS-121-01-LM-DV-P-TR used for?
The HTSS-121-01-LM-DV-P-TR is designed for high-temperature cable-to-board interconnects in industrial automation controllers, servo drive control wiring, and embedded computing modules requiring 42-way signal connectivity near heat-generating power stages. Its 0.100 inch shrouded terminal strip is compatible with standard IDC and discrete wire cable assemblies, making it suitable for panel wiring in PLCs, motor drive I/O expansion boards, and ruggedized test equipment. The tape-and-reel format supports volume SMT assembly in high-throughput PCB production for industrial gateway and control module applications.

Frequently Asked Questions
How many positions and what pitch does the HTSS-121-01-LM-DV-P-TR provide for cable harness termination?
The HTSS-121-01-LM-DV-P-TR provides 42 positions in a single-row layout on a 0.100 inch (2.54 mm) pitch. This contact count suits mid-density cable harnesses used in industrial PLC I/O modules, servo drive feedback wiring, and embedded controller expansion boards where 42 discrete signal or power lines must be routed in a single shrouded connector.
What temperature rating makes the HTSS-121-01-LM-DV-P-TR suitable for industrial enclosure wiring?
The HTSS-121-01-LM-DV-P-TR uses a high-temperature housing rated to approximately 105°C continuous operating temperature, making it appropriate for wiring harnesses routed near motor drivers, power supplies, or other heat-generating components in industrial enclosures where standard 70°C-rated connectors would soften or degrade over the product lifetime.
How does the HTSS-121-01-LM-DV-P-TR polarized shroud reduce field installation errors in 42-way wiring harnesses?
The integral polarizing shroud of the HTSS-121-01-LM-DV-P-TR physically prevents the mating cable plug from being inserted in the reversed orientation, eliminating the risk of miswiring 42 signal lines in field-service scenarios. This is especially valuable in industrial servo drive I/O panels and automated factory equipment where incorrect cable insertion without polarization can damage sensitive encoder or analog sensor inputs operating at 3.3 V or 5 V logic levels.
When should a designer choose the HTSS-121-01-LM-DV-P-TR over a standard (non-high-temperature) shrouded strip?
The HTSS-121-01-LM-DV-P-TR should replace standard 70°C-rated shrouded strips whenever the cable harness runs within 50 mm of components that dissipate more than 5 W, or when the enclosure ambient temperature exceeds 70°C during normal operation. Typical applications include motor drive control boards, industrial power supply secondary wiring, and outdoor embedded equipment exposed to solar heating that can raise enclosure temperatures above 85°C.
