BS EN 4644-021 specifies the size 2 plug for disconnect applications used in the family of modular rectangular electrical and optical connectors with rectangular inserts. The receptacle corresponding to this plug is defined in EN 4644-024 or EN 4644-025 or EN 4644-026.
BS EN 4644-021 covers the terms and definitions, required characteristics, designation, markings, and technical specifications of the connector with rectangular inserts on a size 2 plug with ground block.
BS EN 4644-021 has been prepared by the Aerospace and Defence Industries Association of Europe - Standardization (ASD-STAN).
BS EN 4644-021 on the plug without mounting holes for electrical connectors is useful for:
An electrical connector is a device that connects two active devices to transmit current or signals. Plugs provide reliable protection for all types of de-coupled connectors.
The guidelines provided in BS EN 4644-021 helps to select the right plug as well as a connector as they improve the production process and if an electronic component fails, the failed component can be replaced when an electrical connector is installed.
The guidelines provided in BS EN 4644-021 helps the design engineer with the use of electrical connectors, to have greater flexibility while designing and integrating new products with components as well. BS EN 4644-021 helps design engineers in designing electrical connectors as per specifications that enhance the reliability of their products.
BS EN 4644-021 creates a standardized approach for manufacturers of electrical connectors if they supply their electronic connectors to the aerospace industry.
By adopting BS EN 4644-021, manufacturers can demonstrate the reliability of their products and build trust in their use throughout the aerospace supply chain.
