Abstract
IEC 61076-2-101:2024 describes M12 screw-locking circular connectors with 2-way up to 17‑way, for data transmission with frequencies up to 100 MHz and signal and power transmission at up to 250 V rated voltage and up to 4 A rated current per contact.
These connectors consist of fixed and free connectors, either rewirable or non-rewirable.
Male connectors have round contacts, Ø 0,6 mm, Ø 0,76 mm, Ø 0,8 mm or Ø 1,0 mm according to number of ways and coding, all contacts with the same size.
The different codings prevent the mating of differently coded male and female connectors.
This fourth edition cancels and replaces the third edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Technical specifications regarding dimensional information (Clause 5) and characteristics (Clause 6) have been updated, and new subclauses have been added.
b) New style NF (free connectors) has been added.
c) Fixed connectors with glass to metal seals (former styles WM, XM, YM, ZM and WF, XF, TF and ZF) are no longer covered by this document: relevant definitions and requirements have been removed.
d) The P-coding has been eliminated.
e) Annex B (informative) Steel conduit thread, sizes has been deleted and a new Annex B (informative) Orientation of cable outlet in relation to coding has been added.
f) The dimension specification of former styles AM and BM have been moved into a new Annex C (normative).
