EM1791 Overview
Designed to protect magnetic switches from damage, the Tape & Reel (TR) package contains the switches. For safety reasons, the magnetic switches are packaged in 4-SMD, Gull Wing packages. The magnetic switches can supply 9μA as the maximum current for good performance. If these switches are operating properly, they can output 500μA as their maximum current. If magnetic switches are to be output, the maximum current should be 500μA. Normally, these switches supply 9μA current. For the magnetic switches, 85°C is the maximum operating temperature. This magnetic switch is only effective at temperatures greater than -30°C.
