How does the serial number look like?

The serial number of the encoder is build up like this:

 

  1 2 3 4 5 6 7 8 9
the serial number on the electronic type label Y M W W z z z z p
the serial number on the type label on the encoder y y W W z z z z p

 

The electronic serial number can be read out with the command "56h"

The difference is in the 1st and the 2nd letter.

  • the serial number in the EEprom shows, in the 1st letter, the year in 1 alphabetic character, e.g. Y, Z, A, B, ...
    additionally, the month is shown, in the 2nd letter, as HEX digit, e.g.: 1, 2, 3, ..., A, B, C
  • the serial number of the type label shows the year in 2 letters directly, e.g.: 22, 23, 24, 25, ...

The meaning of the characters:

 

Letter Meaning
Y

year as a alphabetic character (see explanation below)

--> used at the electronic serial number
y

year as number (21 = 2021)

--> used at the type label
M month as a HEX letter (1 = January; A = October; C = December)
--> used at the electronic serial number
W calendar week
z counting number within the week
p product identification

The year letter (Y) as a alphabetic letter has the following meaning:
A 1998 2024
B 1999 2025
C 2000 2026
D 2001 2027
E 2002 2028
F 2003 2029
G 2004 2030
H 2005 2031
I 2006 2032
J 2007 2033
K 2008 2034
L 2009 2035
M 2010 2036
N 2011 2037
O 2012 2038
P 2013 2039
Q 2014 2040

S 2016 2042
T 2017 2043
U 2018 2044
V 2019 2045
W 2020 2046
X 2021 2047
Y 2022 2048
Z 2023 2049

What is the reason for this difference?

The formatting of the serial number (electronic version and type label version) was defined when Hiperface was introduced by the Max Stegmann GmbH in the year 1996.

Since 2002, the Max Stegmann GmbH is part of the SICK AG. This was the reason why the serial number on the type label was changed to the SICK standard.

Due to the fact, that customer systems were used to the old Stegmann format, we decided to keep the format in the electronic serial number.

 

At Hiperface DSL, we decided to use the same format as at Hiperface.
