34、pecified shall be one of the following types: Type A: contact for general application; Type C: contact for thermocouple; Type D: contact with screening feature (including the coaxial contacts, triaxial contacts and bifilar contacts). These have no characteristic impedance and are therefore not recom
35、mended for use at high frequency. Type E: contact with screening feature, including coaxial, triaxial, bifilar and quadrax contacts. These have matched impedance. NOTE Non-removable contacts are defined in the connector specifications. 4.2 Temperature classes The contacts specified shall be from one
36、 of the classes specified below: Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS EN 3155-001:2009EN 3155-001:2009 (E) 7 class P: maximum operating temperature 125 C; class R:
37、maximum operating temperature 150 C; class S: maximum operating temperature 200 C; class T: maximum operating temperature 260 C; class U: maximum operating temperature 350 C. The minimum operating temperature shall be 65 C, unless otherwise specified in the product standard. 4.3 Permissible wires an
38、d cables 4.3.1 The conductors which are acceptable in the crimping barrels and the coding by means of colour bands are specified in ISO 8843. The contact detail specification shall state the acceptable conductors for each size of contact. 4.3.2 The type of cable, coaxial, triaxial, etc. shall be spe

40、emale contact, cylindrical contacts Unless otherwise stated in the product standard, the mating end of female contacts from size 12 to 24, shall be of the restricted entry type and shall not permit the introduction of a gauge which has a diameter 0,13 mm greater than the maximum diameter of the male
41、 contact. 5.1.3 Mating end of male contacts, cylindrical contacts Unless otherwise stated in the product standard, the mating end of the male contacts shall be approximately spherical. A flat is permitted at the end; its dimensions are given in Table 1. Copyright European Committee for Standardizati
