Key Features
- 52-position dual-row 0.100" (2.54 mm) pitch shrouded terminal strip for 52-circuit board-to-cable connections
- High-temperature rated housing suitable for industrial, automotive, and elevated-temperature environments
- Tin-over-nickel (Sn/Ni) contact finish provides corrosion barrier and reliable solderability
- Shrouded housing prevents mis-mating and protects square-pin contacts during cable insertion
- Non-taped (tray or bulk) format available for prototype and low-volume assembly
Applications
The HTSS-126-01-T-DV serves as the board-side mating connector in industrial PLCs, motor control panels, and embedded computing backplanes where 52 signals must be reliably routed over a 2.75 inch span. The shrouded 0.100" dual-row layout simplifies wiring harness assembly by aligning cable connectors automatically and preventing reverse insertion. High-temperature construction ensures performance in HVAC controllers, power electronics enclosures, and fieldbus wiring systems operating above standard commercial temperature ranges.

Frequently Asked Questions
How many circuits and what physical length does the HTSS-126-01-T-DV provide for industrial wiring harness applications?
The HTSS-126-01-T-DV offers 52 positions in a dual-row 0.100" (2.54 mm) pitch layout across a body length of 2.75 inches and a body depth of 0.4 inch. This provides 52 independent signal circuits in a compact footprint, making it well-suited for PLC I/O wiring, fieldbus distribution panels, and multi-axis motor drive cable assemblies.
What contact finish does the HTSS-126-01-T-DV use, and why does it matter for corrosion resistance?
The HTSS-126-01-T-DV uses a tin (Sn) mating contact finish over a nickel (Ni) barrier layer, which prevents tin whisker migration and blocks copper diffusion from the base metal. This Sn/Ni construction maintains contact resistance below acceptable limits over thousands of mating cycles and protects against oxidation in humid or mildly corrosive industrial environments, supporting long service life in 52-circuit wiring harness applications.
Under what conditions would a designer select HTSS-126-01-T-DV over a standard non-shrouded 52-pin header?
A designer selects the HTSS-126-01-T-DV when field technicians must reconnect 52-circuit cable harnesses without risk of pin-1 reversal or partial insertion, since the shroud enforces correct alignment on the 0.100" dual-row pitch grid. The high-temperature housing is chosen when ambient temperatures exceed the 85°C limit of standard commercial connectors, covering applications such as motor drive cabinets, HVAC inverter boards, and industrial sensor hubs.
