GRS-C is a cantilever-mounted rotatable magnetron by Gencoa which combines high load bearing and power delivery. The GRS-C is for horizontal drum type web coating machines with the end-block located outside the chamber side wall, and the target rotating within the chamber.

The GRS-C compact nature and varying target diameters allows multiple sources to be located around the drum.

Its unique design addresses the key points in reliable sputter process delivery with excellent results. The magnetic array angle can be set externally by a hand crank or a stepper motor.

Despite its compact size, the GRS-C can be assembled with targets of up to 2.4m and is vibration-proof and robust. Its cooling and power capacity matches the largest cantilever-style rotatable magnetrons on the market.
