HAL549SF-K Product Details

HAL549SF-K Overview


The magnetic switch is packaged in the Tape & Reel (TR) in order to prevent damage. As a safety precaution, the magnetic switches are packaged in TO-243AA, Variant packages. A magnetic switch can supply a maximum current of 4.2mA if it is well designed. If these switches are operating properly, they can output 20mA as their maximum current. Magnet switches should have a maximum current of 20mA in order to function correctly. There is a limit to 4.2mA current that can be supplied by these switches. Magnetic switches can be set to 140°C for the maximum operating temperature. To ensure that this magnetic switch functions properly, the operating temperature should not be greater than -40°C.
