What Is NPN & PNP in Sensors?

NPN and PNP Output depends on the type transistor used in trigger circuit of sensor.It can be NPN or PNP,when we wire a PNP type sensor and NPN type sensor.

4-20 mA Signal

All your answers are given in this video. We have also seen the use of 0-10 V but we prefer current variation.Analog Sensor Will only give Current 4-20mA current variation.

Cross-Talk in Sensors
Crosstalk occurs when multiple sensors emit sound, and the returning sound pulses are received at different times by a sensor that was not the sender.
