Technical documentation R255EC Series (ELIO)

Applications
The R255EC series circular fiber optic connector is a multi-core environment-resistant fiber optic connector developed on the basis of the R255EC series optical connector. The EC4531 contact has a bayonet locking structure, which can be easily installed in the connector without any removal tools. The rear end of the contact is equipped with a seal, and no tail cover or wire seal is required. It has excellent performance such as vibration resistance, pressure resistance, rain resistance, salt spray resistance, and dust resistance.
The EC4531 contact can be equipped with a No. 8 cavity adapter to meet the ARINC 600 series 8# contact installation hole requirements. The product is suitable for aviation, aerospace, electronics, weapons, ships and other fiber optic communication systems with requirements.
