What is BS 5992-6 - Dimensions of general purpose all-or-nothing relays specification about?
BS 5992-6 is a British standard as a part of the BS 5992 series that specifies the basic dimensional modules to be used in determining the external dimensions of general-purpose all-or-nothing relays and the location of their terminal and fixing centres.
BS 5992-6 applies equally to all such relays regardless of their type of construction (e.g., electromechanical, electronic, reed, etc.) and includes the height of the socket when the relay is socket-mounted.
BS 5992-6 also defines the external dimensions and gives preferred values for these in terms of multiples of the specified modules. The object of BS 5992-6 is to state the following for the external dimensions and location of the terminal and fixing centres for general-purpose all-or-nothing relays:
