The European standard EN 50 262 “Metric Cable Glands for Electrical Installation” was ratified
on April 01, 1989 by CENELEC (European Committee for Electrotechnical Standardization) and
put into force.
A corresponding German standard DIN EN 50 262 published in March 1999
will then replace the national standards:
VDE security standard 0619 quoting standards DIN 46 319 and
DIN 46 320, with a transition period until March 01, 2001.
EN 50 262 is valid in all EC countries and countries not belonging to the EC and cooperating
in CENELEC will accept the standard.
The big difference in the new EN standard is its character as a security standard.
As a building standard it only defines the metric thread and its lead.
The changeover will affect all manufacturers of cable glands, cable entries and housings
for rectangular connectors.
The ten Pg sizes :
Pg 7 / 9 / 11 / 13.5 / 16 / 21 / 29 / 36 / 42 and 48
are replaced by eight metric sizes :
M 12 / 16 / 20 / 25 / 32 / 40 / 50 and 63
As the ten Pg sizes are replaced by eight metric threads, the users have to reassign the con-
nection ranges of the cables to the thread sizes and housings.
The cable gland manufacturers have different assignments because the new standard is not a
construction standard and does not specify any standardization.
