ČSN EN IEC 61076-3-123

This part of IEC 61076 covers hybrid rectangular connectors with a 3 poles 16 A electric portion for power supply and a duplex fibre optic connector type LC portion for data transmission. These connectors consist of fixed and free connectors, either rewirable or non-rewirable (for both portions) and use the rectangular push-pull housing described in IEC 61076-3-117 with IP65/IP67 degree of protection, for harsh applications. The mating dimensions of such housings allow fulfilling the performance class Category I according to IEC 61753-1-3 in regards to the fibre optic portion of the connector with the exception of the operating temperature range which is -25 °C/+70 °C.
