Electrical isolation
9-pin male SUB-D connector
Metallized enclosure
Cable size: 2 * 2 * 0.14 mm² + 2 * 0.25 mm² (AWG 26(4) + AWG 23(2))
2 * 0.25 mm² must be used for the power supply unit and for GND.
The cables have to be twisted in pairs and included in an overall shielding.
The following signal lines have to be twisted in pairs:
Clock - and Clock +
DATA - and DATA +
0 V and power supply
The shield must be connected to the connector housings on both ends of the
cable with the greatest possible surface area.
Material: Copper
Temperature class: 60 °C
Maximum cable length: 100 m
Dependent on the encoder type, the transmission frequency has to be reduced
due to the signal runtimes in long cables.
