E DIN EN IEC 61076-2-118 VDE 0687-2-118:2025-06

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, Table1).
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 have 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 cores are classified by type and identified throughout this standard as “D” followed by “1”, or “2” (see 4.3 Table 3).
Connectors can be identified by data core (D) and complementing power (P) and signal (S) groups and optionally by number of poles, hence by the function provided for field applications.
