Technical Theory

The encoders can be selected with cable or connector. If you choose the connector option, you will need a mating connector or a cordset (both connector and cable). This will give you a connection point to the encoder but does not necessarily get you all the way to your control cabinet. Depending on the distance, you may need a junction box, conduit, and cable tray. Care should be taken when routing encoder cable to reduce the influence of "noise". To reduce this influence, the cable should have a braided shield around the wires and the wires should be twisted pair. The encoder cable should be in a conduit with only low DCV cables and keep AC and high-power cables separated. If there are cable trays with AC and DC cables, there should be a grounded metal divider between the DC and AC cables. If the encoder cable does need to cross an AC cable, it should cross perpendicular (90 degrees to each other). The shield should be connected to one earth ground location in your control cabinet (so it has a star topology).
