Description: This sucked electromagnet is widely used in the transportation and delivery of material products in the laboratory equipment, medical treatment, grinding, cutting, cutting and other automated processing production lines. Easy to control and remote operated. Saving energy, safe and reliable. Suction cup electromagnet requires the object surface should be as flat as possible, and the absorption area should not smaller than the suction surface, otherwise it will affect the suction, the effective distance is 0. The suction can be adjusted by adjusting the voltage within the rated voltage range, DO NOT above the voltage range. Specification: Material: metal Model: XRN-P49/21 Voltage: DC12V Suction: 40kg/400N/88.18lb Size: Outer Dia.: approx. 49mm/1.93inch Height: approx. 21mm/0.82inch Suction Surface Dia.: approx. 22mm/0.87inch Package Includes: 1 Piece Sucker Electromagnet Note: Please allow slight dimension difference due to different manual measurement
