The HD34-24-31PT-B019 is a receptacle connector from the DEUTSCH HD30 series designed for use in industrial and commercial transportation systems. It features a 24-shell size with 31 contact positions and utilizes pin contacts (P designation) with standard diameter wire seals (N designation) to maintain environmental sealing in rear connector cavities. The connector is part of the HD30 family, which provides robust connectivity solutions for on-board CAN systems, diagnostic interfaces, and power distribution in vehicles and heavy equipment. The standard wire seal accommodates 14–20 AWG wire (2.0–0.5 mm²) with an outside diameter range of 0.100–0.150 inches (2.54–3.81 mm). This receptacle connector is commonly used in agricultural, construction, and transportation applications where reliable environmental sealing and high-density contact configurations are required.
