SFA-5000 / SFA-10000 is the extensive range of cable-pulling measuring systems with integral absolute encoder. It is offered in a wide choice of Ethernet and fieldbus interfaces:
Profinet, EtherNet/IP, EtherCAT, POWERLINK, MODBUS TCP, Profibus, CANopen, DeviceNet,
The working principle of SFA draw-wire encoders relies on the back-and-forth movement of a robust stainless steel measuring wire fixed to the moving axis, controlled by the absolute encoder (the wire is pulled out and rewound). The measuring wire is able to reach measuring lengths up to 5,000 mm (196.85”) and 10,000 mm (393.7”) and can operate at a maximum speed of 2 m/s (78.7 inches per second). The flexibility of the wire enables linear paths to be measured and even curved paths through guiding rollers. They are also ideally suited for a variety of industrial applications. The enclosure is compact and rugged and provides IP65 protection.
SFA draw-wire encoders come in a large variety of Ethernet and fieldbus models and offer the full set of information and configuration parameters: position and velocity readout, full scaling with resolution programmable down to 0.024 mm (24 µm), preset, code sequence, extensive diagnostics, Ethernet and bus network settings.
Wire-actuated encoders can replace standard encoders in many uses. They can be a good solution, when the operational space is constricted or the environmental conditions are severe.
The encoder body in fact can be mounted in a safe place, easily accessible, and adequately protected. While the measuring wire requires minimum space and can be subjected to harsher conditions. Typical applications are mobile equipment and construction machinery (outriggers, stabilizing slides, booms), telescopic cranes, bucket trucks, forklift trucks, automated guided vehicles, agricultural/forestry machinery and equipment, scissor lifts, car lifts, loading platforms, warehouses, electro-medical equipment (computed tomography scans, operation and examination tables, hospital beds and dentist's chairs, etc.).
