For safety reasons, these analog sensors are enclosed in the Tape & Reel (TR). It is important to protect analog sensors by packaging them in 20-SSOP (0.154, 3.90mm Width) packages. To operate properly, the sensor has pins 20. DC circuits should have a maximum voltage of 5.5V. In a DC circuit, this magnetic switch can produce 3V as the minimum voltage. When it operates, analog sensors can provide 5.5V voltage.
