1 Scope

This part of IEC 61076 covers 8-way, shielded, free and fixed rectangular connectors for I/O and data transmission with frequencies up to 500 MHz. It is intended to specify the common dimensions, mechanical, electrical and environmental characteristics and tests for this family of connectors.

Connectors complying with this document provide an ingress protection level of IP20; however, they are particularly suited for industrial environments with a high level of vibration.

NOTE 1 In terms of the MICE system as defined in ISO/IEC 11801‑1, the connector matches the requirements of the M₃I₁C₃E₃ levels.

There are two classes of connectors defined in this document, indicated by "class A" and "class B" which are distinguished by some electrical and mechanical characteristics to meet the particular sets of requirements of some industrial applications.

NOTE 2 Class A meets the requirements defined in Ed.1 of this document.

NOTE 3 With the two classes A and B, the two codings Type I and II, and the two sets of transmission requirements according to the component categories Cat 5 and Cat 6_A as defined in ISO/IEC 11801‑1, this document specifies $2 \times 2 \times 2 = 8$ variants.

All connectors covered by this document feature a current-carrying capacity beyond the minimum requirement of 0,75 A per pin for an ambient temperature of 60° C as defined in ISO/IEC 11801‑1.

NOTE 4 The current-carrying capacity is given by the current-temperature derating defined in this document and is dependent on the wire size of the cable attached to the connector.

NOTE 5 With a current-carrying capacity of 0,5 A per pin and with matching the requirement of withstanding the test current of 2 A for unmating under load as defined in IEC 60512‑99‑002, the connectors covered by this document support the highest Power over Ethernet level as defined by IEEE 802.3bt (100 W PoE++ Type 4).
