ABL-254-56-SR45

Headers, Receptacles, Female Sockets Overview

The ABL-254-56-SR45 is a 56-position female surface mount header connector from the Assmann WSW A-BL254 series. It features a 0.100 inch (2.54 mm) pin-to-pin spacing and a dual-row configuration with straight (180°) orientation. The contacts are made of bronze with gold plating, rated for 3A current and 500V voltage. Designed for PCB mounting, it operates within a temperature range of -40°C to 105°C and utilizes UL 94 V-0 rated housing material.
