Quadrature Cable

Part Number: RMC-CB-QUAD-01-xx

 

A cable can be purchased that connects directly to the RMC150 Quad module or the RMC75E QA1 and QA2 modules' DB-25 connectors. The cable can be purchased in one of three lengths.  It separates the wires into three groups: drive, encoder, and limits.  Each group has its own braided shield and insulation.

Part Number

RMC-CB-QUAD-01-06

RMC-CB-QUAD-01-10

RMC-CB-QUAD-01-015

Length

6 feet (2 m), 10 ft (3 m), or 15 ft (4.5 m)

Connector

DB-25 male with shielded housing (mates to connector on RMC QUAD)

User Connections

Flying leads (pigtails)

Cable

Each DB-25 connectors has three cables coming from it.  Each has 24-gauge twisted pairs with an overall braided shield:

  • Drive (3 pair):
    Amplifier connections

  • Encoder (4 pair):
    Quadrature encoder connections

  • Limits (3 pair):
    Home and limit switches

Wire Colors

Notice that the cable connects to the same pins for the QA1, QA2, and QUAD modules, because these modules have identical pinouts.
