In machines and equipment, there is a need for flexible I/O interfaces for applications involving rotating tables, moving pallets, punches, and forming dies. Interfaces of this type require that the sensors follow the movements of the machine. The operation cannot be obstructed by the wiring of the cables. Applications such as this are not possible with fixed or hardwired connections.

The use of the Balluff Remote Systems is a proven technology to solve the problems and demands of flexible automation.

Remote systems allow the transfer of signals to a controller through an air gap without the need for physical contact or hardwiring. A remote system consists of three components: the output sensor, transmitter, and the detector sensors. The output sensor connects to the power source and inputs of a controller. When power is applied to the output sensor, the coil is energized. When the transmitter is placed within the sensing range, the transmitter is inductively coupled and powered, allowing the transfer of power to the detector sensors. When the detector sensor sees a target, the output produced is transmitted through the transmitter across the air gap to the controller.
