CWN-551-20-0000

Headers, Male Pins Overview

The CWN-551-20-0000 is a vertical header connector manufactured by CW Industries, designed for board-to-board or cable applications. It features 20 positions arranged in a dual row with a 0.100-inch (2.54mm) pitch. The connector utilizes male pin contacts made of phosphor bronze, finished with gold plating on the mating interface and nickel on the tail. Rated for 1A current, it operates within a temperature range of -55°C to 125°C. The insulator is blue thermoplastic material rated UL94 V-0. Key mechanical features include an insulation height of 0.681 inches, a mating contact length of 0.240 inches, and push-pull locking mechanisms.
