Why should you use BS EN 4165-021 - Coupling system keyway for plug?
Keyway connections are made comprised of slots cut into one part of the coupling and a key on the other. The keying mechanism provides different position keying capabilities. These positions are given different coding pins which are identified by different colours.
BS EN 4165-021 provides users guidance on required characteristics for coupling system keyway for plug, including dimensions, design, and positions for standard key, purple key, yellow key, green key, blue key, orange key and white key, enabling users to adopt standardized positions to accurately identify and classify in keyway connections.
With obedience and compliance to BS EN 4165-021, users can develop and assess coupling system keyway for plug, ensuring stable operability, thermal resistance and performance in high-temperature aerospace applications.
