More power and precision in electro-hydraulic cylinders

Parker Hannifin’s new HMIX cylinder is a fully integrated sub-system which combines tie-rod cylinder technology with a high precision feedback transducer, manifold and pipework into a single unit.

The system design reportedly enables machine developers and builders to enhance the functionality and performance of machine systems, while reducing installation, configuration and maintenance times.

The internally mounted magnetostrictive transducer provides continuous analogue or digital feedback of the actuator’s position, derived from the interaction of two magnetic fields.

These are reportedly generated by a permanent magnet attached to the actuator piston, and by a magnetic pulse produced by a current pulse launched along a copper core inside a waveguide tube, which runs the length of the piston rod.

The system also features a non-contacting transducer design, tough steel protection tube for the transducer electronics and connector, and high tensile, carbon alloy steel piston rods as well as one-piece steel piston, mechanically locked to the rod

The HMIX electro-hydraulic cylinders are are available in a range of eight mounting styles, with bore sizes from 40mm to 200mm and stroke lengths of up to 3000mm. Typical applications include machine tools, plastic injection moulding machines, welding machines and test equipment.
