A3250LUA Overview
In order to protect the magnetic switch from damage, it is packaged in the Bulk enclosure. For safety reasons, magnetic switches are packaged in 3-SSIP packages. To ensure good performance, the magnetic switches are capable of delivering 7mA as the maximum current. It is possible for these switches to operate at a maximum current of 20mA. This has 3 terminations. When this switch is functioning, its maximum voltage should be 24V. When this switch is operating reliably, it will supply 12V voltage. There is 4.5V minimum voltage that this magnetic switch can provide.
