Customer cables that interface to Mercury II ™ series
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 the encoder, for example
24AWG gauge wire for a 2m length cable.
Examples of acceptable cables with 24AWG
gauge wire and 4 twisted pairs are Belden
9831, 8104, and 9844 or other
manufacturer’s equivalents.
• Single shield cable with a minimum of 90%
coverage. Note that a double shielded cable
may be required in high-noise applications.

Signal Wiring
Each differential signal should be connected to
a corresponding twisted pair as follows:
