It is for safety reasons that these analog sensors are packaged in the Tube. A 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package protects the analog sensors from damage. As a result, the sensor has 8 pins for proper operation. In this electronic component, there are 8 terminations. It is possible that the current supplied by the analog sensors could be 12μA when it operates. DC circuits require a maximum voltage of 5.5V. DC circuits with this magnetic switch can supply 3V as a minimum voltage. If the analog sensors were operating, they could supply 5.5V. This device has 8 pins. Normally, this sensor will provide a voltage of 3.3V.
