Magnetic Stimulation Accessories CatalogueMCF-B70 Butterfly Coil• The coil has electrical and magneticproperties similar to the MC-B70.• The Coil is designed for demandingclinical studies, requiring a high number ofstimuli without the need for externalcooling. Number of stimulations up to 3times more than MCF-B65.• The coil is produced with a slightly bentsurface to closely follow the shape of thehead. Motor threshold is achieved at 10%to 20% lower output compared to MCF-B65.• Large ergonomic handle.• Equipped with trigger button to supportclinical operation.Mechanical PropertiesWeight of transducer head 2.5kgCable length 1.3mDimensions of transducer head 180 x 116 x 45/64 mmAngle 150°Coil Winding DataInner diameter23mmOuter diameter97mmWinding height12mmNumber of windings 2 x 11Magnetic and Electrical PropertiesMax initial dB/dt28 kT/s near the coilsurfaceActive pulse width280μs (Biphasic)PerformanceNumber of stimulations before 5500 pulseswarm-up at ambient temperature20°C:Mean output 75% of maximumat 1pps.Protocol: 60 trains @ 50pulses/train @ 10pps @ InterTrain Interval: 25s @Output=75% @ total number ofstimulations 3000One protocol can beperformed withoutoverheating the coil.Minimum cooling timebetween protocols:2.5 hours at 20°C or1 hour at 7°COrdering Number 9016E040-23
