EN 4008-005:2006

Overview

EN 4008-005:2006 is a European standard that specifies the product requirements for the positioner used with the M22520/2-01 crimping tool. This positioner is a critical accessory for crimping electrical contacts in aerospace applications, ensuring precise and reliable connections as dictated by the aerospace series elements of electrical and optical connection. Developed under the auspices of the AeroSpace and Defense Industries Association of Europe (ASD-STAN) and endorsed by CEN, this standard facilitates consistent quality and interoperability for aerospace electrical systems.

Key Topics

• Scope and Application
  Defines characteristics for a positioner component designed exclusively for use with the M22520/2-01 crimping tool. It focuses on achieving accurate longitudinal positioning of electrical contacts in compliance with EN 4008-002.

• Design and Functional Requirements

  • Positioner retention on the crimping tool uses two bayonet locks and a spring-loaded central locator.
  • The locator must provide a precise depression of 0.79 mm with a force of 9 ± 4.5 N to ensure the accurate placement of contacts.
  • Material specifications include a blue aluminium alloy body and stainless steel ferrule for durability in demanding aerospace environments.

• Dimensions and Tolerances

  • The positioner’s maximum mass is 30 grams.
  • Precise dimensions and tolerances (±0.25 mm) are mandated to ensure compatibility and repeatability.

• Marking and Identification

  • Clear product marking requirements are outlined for traceability, with examples provided for designation.

• Associated Standards Referenced
  Includes full alignment with related aerospace standards such as EN 4008-001 (technical specifications), EN 4008-002 (crimping tools), EN 2591-100 (test methods), and electrical contact product standards (EN 3155-032, EN 3155-033).
