This part of IEC 61076 specifies circular connectors with size B12, B17, B23 and B40 with bayonet-locking, typically used for power, signal and data transmissions in industrial applications. These connectors consist of fixed and free connectors either rewirable or non-rewirable.
Power contacts of male connectors are round contacts with Ø 1 mm, Ø 1,5 mm, Ø 1,8 mm, Ø 2,25 mm and Ø 4 mm, with current ratings up to 64 A per pole and rated voltage of 50 V, 300 V or 600 V AC/DC. Power contact groups are classified by type and identified throughout this document as “P” followed by two digits “01” through “09” (see 4.3, Table 1).
Signal contacts of male connectors are round contacts with Ø 1 mm and Ø 1,8 mm, with current ratings up to 20 A per pole and rated voltage of 50 V AC/DC. Signal contact groups are classified by type and identified throughout this document as “S” followed by “0”, “1”, or “2” (see 4.3, Table 2).
Data contacts of male connectors are round contacts with Ø 0,8 mm and Ø 1 mm, with current ratings up to 8 A and rated voltage of 50 V AC/DC, Data transmission performance with frequencies up to 600 MHz. Data modules are classified by type and identified throughout this standard as “D” followed by “1”, or “2” (see 4.3, Table 3).
Besides the size of their bayonet locking (B12, B17, B23 or B40), connectors according to this document can be identified by data module (D) and complementing power (P) and signal (S) contact groups and optionally by number of poles, and finally by their application.
These connectors are designated for two main target applications, which differ as follows:
• Application A is for data transmission with power over data
• Application B is for data transmission without power over data
Connectors with power, signal and data contacts of the same gender are intended to transmit also power over the data contacts (application A), while connectors with data contacts not of the same gender of power and signal contacts are not intended to transmit power over the data contacts (application B).
The codings provided by this document prevent the mating to any other connector with similary sized interfaces covered by this document.
NOTE: B indicates that the connector is equipped with bayonet locking, while 12, 17, 23, 40 are the approximate dimensions in millimetres of the contact carrier diameter of these circular connectors.
