For safety reasons, these analog sensors are packaged in the Tape & Reel (TR). Putting analog sensors into 20-TSSOP (0.173, 4.40mm Width) packages prevents them from being damaged. As a result, the sensor has 20 pins for proper operation. Ideally, this sensor should provide a voltage of 5.5V in a DC circuit. In the DC circuit, however, this magnetic switch can provide a minimum voltage of 3V. Analog sensors are capable of supplying 5.5V voltage when operating.
