EM6781 Overview
Magnetic switches are packaged in Tape & Reel (TR) to prevent damage. In order to ensure safety, magnetic switches are packaged in TO-236-3, SC-59, SOT-23-3 packages. As a maximum current, magnetic switches can supply 9μA. If they are working properly, these switches can output a maximum current of 500μA. A magnetic switch should only output 500μA current. It is possible for these switches to supply a maximum current of 9μA. Magnet switches can be set to operate at 85°C. The operating temperature of this magnetic switch must not be lower than -30°C.
