SIST EN 4640-003:2008

Overview

SIST EN 4640-003:2008 is a European standard developed by CEN that specifies the product requirements for aerospace-grade plug optical connectors. These connectors are rectangular, rack and panel mounted, and designed with multicontact interfaces featuring a 1.25 mm diameter ferrule and a removable alignment sleeve holder. This standard ensures high-quality, reliable optical connectivity tailored to the stringent demands of aerospace electrical systems and equipment.

The standard is part of a broader aerospace series focused on optical connectors, ensuring compatibility and standardization for aerospace applications. It aligns with ARINC Specification 600, which governs air transport avionics equipment interfaces, providing dimensional and mechanical consistency.
