What is BS EN 186130 - Type LSA about?
BS EN 186130 discusses a harmonized system of quality assessment for electronic components. Harmonized system of quality assessment for electronic components is an internationally standardized system of names and numbers to classify traded products.
BS EN 186130 covers type LSA fibre optic connector sets. Type LSA defines single way connectors with a M 5,5 mm× 5 mm screw thread coupling mechanism and a cylindrical butting ferrule of 2,5 mm nominal diameter. BS EN 186130 contains the requirements for type LSA connector sets.
Who is BS EN 186130 - BS EN 186130 - Type LSA for?
BS EN 186130 on Type LSA for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use BS EN 186130 - Type LSA?
Harmonized systems of quality assessment for electronic components are organized logically by economic activity or component material. To ensure the general interpretability of connectors following BS EN 186130 a minimum clearance of 0,5 4m must be kept within the temperature range of the specified climatic category. If different materials are used the specific coefficients of expansion have to be considered. As a basic a coefficient of expansion of! = 6.10–6 K–1 has been defined. For those connectors which are specified for a temperature range from + 5 °C to + 55 °C the single limit mating face dimension for ferrule and sleeve can be determined from the following diagram.
This diagram shows the dependency of the diameters of the sleeve and ferrule on the temperature with respect to different coefficients of expansion. The temperature can be read from the X-axis. The deviation from the nominal diameter is given on the Y-axis. The coefficient of expansion! = n·10–6 K–1 is represented by a lot of curves signed with the parameter n for ferrules and sleeves respectively. The unknown single limit mating face dimensions can be determined from the Y-value. Using BS EN 186130 you can specify the type LSA fibre optic connector sets.
