For safety reasons, these analog sensors are packaged in the Tape & Reel (TR). As a measure of protection, analog sensors are enclosed in 20-SSOP (0.154, 3.90mm Width) packages. As a result of this sensor's 20 pins, it can be operated properly. The maximum voltage supplied by this sensor should be 5.5V in the DC circuit. However, this magnetic switch can supply 3V voltage in DC circuits. During operation, the analog sensors can supply 5.5V voltage. In this case, it has 20 pins.
