BS EN 3155 is a European standard on electrical contacts used for elements of connection.
BS EN 3155-075 specifies the required characteristics, tests and tooling applicable to female electrical quadrax contacts, shielded, size 8, type E, class R used in elements of connection according to EN 3155-002.
BS EN 3155-075 is to be used with BS EN 3155-001.
The associated male contacts are defined in EN 3155-074.
The contacts defined in BS EN 3155-075 are designed for size 8 polarized connector cavities.
BS EN 3155-075 on female electrical quadrax contacts for aerospace is applicable to:
Female contact is used for electrical, physical, or data transfer and is generally a receptacle that receives and holds the male contact and are more resistant to damage or contamination.
Quadrax contacts are type E contacts with screening feature specify high frequency characteristics and class R corresponds to an operating temperature range from -65°C to 150°C. Quadrax contacts consist of an outer contact with four inner contacts spaced to form two 100 or 150 Ohm controlled impedance differential pairs.
BS EN 3155-075 assists aerospace industries as well as testing agencies in manufacturing and testing aerospace products with respect to proper dimensions, colour code, tensile strength, and alloy.
BS EN 3155-075 assist design engineers in designing electrical contacts as per specifications and enhances the reliability of their product.
BS EN 3155-075 covers all the requirements for female electrical contacts. It creates a standardized approach for manufacturers of electrical connectors if they supply their metallic materials to the aerospace and defence industry.
With obedience and compliance to BS EN 3155-075, manufacturers can demonstrate the reliability of their female electrical quadrax contacts with size 08, type E, crimp, class R, and build trust in its use throughout the aerospace supply chain.
