BS EN IEC 61076‑3‑123 is one of the series of international standards used for connectors for electrical and electronic equipment that specifies the characteristics, measuring methods and procedures.
The test method helps in ensuring the sustaining of the rectangular connectors in different environmental conditions which result in producing good quality electronic equipment.
BS EN IEC 61076‑3‑123 covers hybrid rectangular connectors with 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 regard 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.
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.
Note: Only the phase or neutral contacts are loaded upon the 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).
BS EN IEC 61076‑3‑123 on connectors for electrical and electronic equipment is useful for:
Connectors are useful in joining the circuits together and the rectangular connector is a system of housing that inserts and contacts together to offer robustness.
BS EN IEC 61076‑3‑123 guides you in determining the compatibility and performance level of rectangular used in electrical and electronic equipment.
The dimension for the fixed connector mentioned in BS EN IEC 61076‑3‑123 is useful in designing and constructing the rectangular connectors used in electronic equipment.
The electrical properties of connectors are specified in BS EN IEC 61076‑3‑123 that aid in the resistance to the shield and insulation, as well as in estimating the current capacity of the connectors.
Overall, BS EN IEC 61076-3-123 guides you through the electrical, mechanical, and technical features that are important in evaluating the performance of connectors, which are a system of housings, inserts, and contacts that work together to provide a durable, secure, and simple-to-assemble solution. The measuring method and test procedure verify the quality of rectangular connectors used in electronic equipment to supply electricity from circuits.
