14、ve applications requiring high performance.

Example 169-15 IEC-G1 (40/85/21) denotes a connector with mating face as specified in Clause 5 of this standard belonging to climatic category 40/85/21. NOTEIn the present standard, Grade 2 is under consideration. Deviating from normal practice, the dim

16、ensions and tolerances are specified for Grade 1 connector (see Clause 5). Dimensions and tolerances of the Grade 0 connector are specified in Sub-clause 6.2. 3 Ratings The r.f. connectors defined in this standard are designed for use with a variety of flexible and semi-rigid coaxial cables and rigi

17、d coaxial lines and Grade 1 will not introduce a reflection factor greater than 0.1 at frequencies up to 24 GHz under optimum conditions. NOTE“Under optimum conditions” means that all circumstances are the best possible, for instance straight connector, mounting to a rigid or semi-rigid line, carefu

18、l manufacturing. Bearing in mind the design concept of the connector, the reflection factor specified under the optimum conditions should be achievable in practice, the percentage of connectors from any production batch failing to obtain the specified performance being reasonably low. The following

19、limits for coupling torque are recommended: minimum: 0.791 Nm; maximum: 1.130 Nm. Working voltage: Current: 0.25 A d.c. maximum. 4 Preferred climatic categories (see IEC Publication 68: Basic Environmental Testing Procedures) NOTESelect climatic category to suit cable used.
