Leitreihen

Leitreihen, a German term roughly translating to "leading series" or "reference series," is a concept used in various fields, particularly in engineering and design, to denote a standardized sequence of values or dimensions. The primary purpose of a Leitreihe is to simplify design processes and ensure interchangeability and compatibility between components. Instead of allowing for an infinite range of possible dimensions, designers are encouraged or required to select values from a predefined Leitreihe.

This standardization offers several advantages. It reduces the number of different parts and components that need to be manufactured and stocked, leading to cost savings and increased efficiency. It also facilitates assembly and maintenance, as parts from different manufacturers adhering to the same Leitreihe are likely to fit together. Examples can be found in screw thread sizes, standard shaft diameters, or even preferred resistance values in electronics. The concept promotes modularity and a systematic approach to product development, ensuring that components can be easily integrated into larger systems. While the specific Leitreihen vary depending on the application and industry, the underlying principle of establishing a limited, standardized set of values remains consistent.
