Customer Interface Cable Requirements
Customer cables that interface to LSC20 encoders must have the following
characteristics:
• Twisted pair signal wiring.
• Characteristic impedance of 100-120 ohms.
• Sufficient wire gauge to meet the minimum voltage requirement at
• Single shield cable with a minimum of 90 % coverage. Note that a dou-
