In order to protect the magnetic switch from damage, it is packaged in the Tape & Reel (TR) enclosure. In order to protect the switches from damage, they are packaged in 3-SIP packages. In order to function well, magnetic switches should be able to supply a maximum current of 8mA. If these switches are operating properly, they can output 15mA as their maximum current. In order to be output, magnetic switches should have a maximum current of 15mA. It is possible to supply 8mA current with these switches. Switches have 3 pins for operation. Magnetic switches can operate at a maximum temperature of 115°C. This magnetic switch is only effective at temperatures greater than -20°C.
