BS EN IEC 61076-3-123:2019

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.

The electric portion may have different rated insulation voltages. Male connectors have 3 electric round contacts Ø1,6 mm, with 16 A rated current.

NOTE Only the phase/neutral contacts are loaded upon current-carrying capacity test of 4.4 and 6.4.3 and electrical load and temperature test in 7.2.2.6 (DP2) and 7.2.2.12 (KP5)

The fibre optic portion provides data transmission by using the common mating configurations for all variants of the type LC duplex fibre optic connectors as defined in IEC 61754-20, for dedicated fibre types and fibre termination technology covered therein.

The different codings provided by this document prevent the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards and the cross-mating between the different codings provided by this document.
