Overview
IEC 61076-3-115:2009 is an international standard published by the International Electrotechnical Commission (IEC) that specifies product requirements for protective housings used with 8-way rectangular shielded and unshielded connectors. These connectors operate at frequencies up to 600 MHz and are designed specifically for industrial environments. This standard incorporates the interface specifications from the IEC 60603-7 series and focuses on Variant 12, related to IEC 61076-3-106, which uses a push-pull coupling type.
The main objective of IEC 61076-3-115 is to enhance existing 8-way connector systems by providing detailed specifications for protective housings that upgrade connectors to meet IP65 and IP67 ingress protection ratings as defined in IEC 60529. This makes these connectors highly suitable for use in harsh industrial environments where resistance to dust and water ingress is critical.
