Overview

The 51740-10202402AALF is a 28-position vertical receptacle from the Amphenol PwrBlade series designed for high-power board-to-board connections. It combines power blades and signal contacts into a single housing, supporting up to 30A per power contact and 300V. This through-hole connector features integrated board locks and guide pins to ensure secure mechanical alignment and stability during the soldering process.

Why Choose This Part

This connector offers a high current density with a 30A rating per blade and a low contact resistance of approximately 0.7 mohms, minimizing thermal dissipation. The shrouded design and high-temperature thermoplastic housing with a UL94V-0 rating ensure safety and durability in demanding environments. Integrated guide pins facilitate blind mating, reducing the risk of contact damage during system assembly.
