E-Z met™ 2mm Hard Metric Type AB-25 Header, Straight


Type AB-25, Vertical Male 125 Pin Connector


The E-Z metf type AB vertical male connector provides 125 signal contacts and an optional 44 ground shield contacts in a 5+2, 25 position configuration. The Type AB connector does not have a multifunction block for coding, thus providing an extra 15 signal contacts. The type AB connector is designed to be used by itself or together with type B, C, L, M or N E-Z metf connectors.


ECS offers 15 different standard tail lengths to choose from to provide various premate and midplane configurations. Contacts can be selectively loaded to accommodate customer specific applications. Custom tail lengths and mold configurations are also available. For non standard loading, or custom applications, please email ECS at custsvc@ecsconn.com.
