A3251LUA Overview

Magnetic switches are packaged in Bulk to prevent damage. For safety reasons, magnetic switches are packaged in 3-SSIP packages. For good performance, magnetic switches can supply 7mA as their maximum current. When they work, these switches can output 20mA as their maximum current. Switches work with 3 pins. It has 3 terminations. Switches should generally output 20mA current. When this switch is working, it should supply a voltage of 24V . For reliable operation, this switch supplies 12V voltage. Magnetic switches can supply voltages as low as 4.5V.
