Intrinsically safe explosion-proof compound cable, signal processor provided with the intrinsically safe explosion-proof compound cable, teach pendant provided with the intrinsically safe explosion-proof compound cable, and robot provided with the intrinsically safe explosion-proof compound cable

摘要

An intrinsically safe explosion-proof compound cable includes a plurality of unit cables. Each of the unit cables is configured to transmit a signal or power. The plurality of unit cables include one or more shielded cables each having a shield layer and one or more unshielded cables without the shield layer. At least a highest-frequency unit cable that is the unit cable configured to transmit the signal or power at the highest frequency among the plurality of unit cables is the unshielded cable.
