                                                A1220EUA-T Overview
Magnetic switches are packaged in Bulk to prevent damage. As a safety precaution, the magnetic switches are packaged in 3-SSIP packages. Good performance is achieved by magnetic switches that can supply 4mA as maximum current. In operation, these switches can output a maximum current of 25mA. To output current, magnetic switches should be set to 25mA. This switch can supply a maximum of 4mA amps. During operation, the switches have 3 pins. The switches should typically output 25mA of current. It is possible to set the maximum operating temperature for magnetic switches to 85°C. Nevertheless, this magnetic switch must not operate at temperatures below -40°C. A maximum voltage of 24V can be provided by this electronic component. As a minimum voltage, these switches can supply 3V.
