The general pattern of our symbols is:
XX-HY-0Z K* VV
XX - stands for the interface of a products (1-Wire or RS232)
HY - refers to the height of a coil described in millimetres
Z – gives us information about the number of wires in cable and consequently about the LED diode.
03 – three wires. No LED diode
04 – four wires. Single colour LED diode
05 – five wires. Bicolour LED diode
06 - six wires. Bicolour LED diode
K* - an optional version of reader with a common cathode
VV – provides additional information about the product:
M12 – mounted with M12 thread
WR – (water resistant) stands for additional, waterproff plastic casing (WR readers are mounted with an M12 thread)
P - side-conduction of the flat wire
BZ - additional buzzer that can provide sound notification
The difference between reader with a common anode and a common cathode comes down to the configuration of LED in a reader. It is well explained in pictures given below:
