20455-A20E-76

Headers, Receptacles, Female Sockets Overview

The I-PEX 20455-A20E-76 is a CABLINE-VS series receptacle connector featuring 20 positions with a 0.020-inch (0.50mm) pitch. It utilizes surface mount, right-angle termination for board-to-cable applications. The contacts are made of phosphor bronze with gold plating, while the insulation is black liquid crystal polymer rated UL94 V-0. Rated at 100VAC and operating between -40°C and 85°C, it includes shielding and a latch support.
