Technical Parameters:Working Voltage: 12VSuction: 35NDiameter: 25mm/0.98"Height: 20mm/0.79"Description:1. Electric Magnet can be used in the transportation and delivery of material products in the laboratory equipment, treatment, grinding, cutting, cutting and other automated processing production lines.2. Electric Magnet requirements of the object surface should be as flat as possible, and the adsorption area should not be less than the suction side of the electromagnet, otherwise it will affect the suctionNote:1.The Force will be decrease due to long time working ,lower voltage and improper Sucked object ect.2.Please pay attention to the size before purchasing, make sure our product is right what you want.
