General Rules for Implementation

About us
Installation
Connecting or disconnecting the standard 15 pin SUB-D connectors of the TSX CTY 2A/ 4A/ 2C modules to/from the encoder and sensor supplies present is not recommended as this may damage the encoder. Some encoders cannot withstand sudden and simultaneous signal and supply power-ups or outages.
General wiring instructions
Wire sections
Use wires of a satisfactory section to avoid drops in voltage (mainly with 5 V) and overheating.
Example of falls in voltage for encoders supplied with 5 V with a cable length of 100 meters:

Connection cable
All cables carrying the sensor supply (encoders, proximity sensor etc.) and the counting signals must:
The connection cable between the module and encoder should be as short as possible to avoid creating loops, as the circuit capacities can interfere with operation.
NOTE: If necessary, direct the flow of the signal in the same cable as the supplies. Cables with twisted pairs should preferably be used for this.
