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:

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 66 67
