European foreword
This document (prEN 3660-065:2025) has been prepared by ASD-STAN.
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 3660-065:2022.
This document includes the following significant technical changes with respect to EN 3660-065:2022:
— addition of classes V and D (tin-zinc): update of Table 2 (nominal mass), Subclause 4.5 description of
material and finish, assembly torque in Table 7, tests in Table 8;
— update of Figure 1;
— addition of Table 6 “Hexavalent chromium compound list”.
1 Scope
This document defines a range of cable outlets, style K, 90°, shielded, sealed, self-locking (anti rotational)
for heat shrinkable boot, and or with metallic bands under the following conditions.
The mating connectors are listed in EN 3660-002.
Temperature range Class N: −65 °C to 200 °C;
Class K: −65 °C to 260 °C;
Class W: −65 °C to 175 °C;
Class T: −65 °C to 175 °C (Nickel PTFE plating);
Class Z: −65 °C to 175 °C (Black zinc nickel plating);
Class V: −65 °C to 175 °C (Tin zinc plating, non-reflective);
Class D: −65 °C to 175 °C (Tin zinc plating, dark, non-reflective).
Associated electrical accessories: EN 3660-033 Metallic band (for shield termination).
These cable outlets are designed for termination of overall shielding braid and/or individual cable
shields. They accommodate/permit the termination of heat shrinkable boots.
