Proximity Sensor Npn Vs Pnp

Proximity Sensor Npn Vs Pnp. It switches the ground/negative side, whereas a pnp switches the positive side to power i.e. Both types are used for the same purpose;

For npn sensors, the positive side is connected to common. Hence it is known as sourcing sensor. The plc input supplies voltage and the sensor grounds the voltage, then current flows.

All Models Provided With An Operation Indicator.


The relevant difference is output. Npn sensors are also known as current sinking. What is the difference between npn and pnp proximity sensors.

If A Pnp Cable Is Damaged There Is A Chance The Signal Could Short To Ground And Damage The Sensor.


I added a 10k resistor between output and gnd. If the readout changes to a number between 10 and 30, then the sensor output is a pnp type, also known as sourcing. if the meter display remains at 0, then the sensor output is an npn type, also known as sinking. if you believe that the sensor is npn, there is an additional test that may be done to confirm. Pnp sensors are also known as current sourcing.

With Respect To Sensors, An Npn Device Is One That Can Switch The Negative Side Of The Circuit While A Pnp Device Switches The Positive Side.


Mungkin kita sudah biasa memahami model istilah kontak nc (normaly close) & no (normaly open) pada suatu sirkuit, It switches the ground/negative side, whereas a pnp switches the positive side to power i.e. Hence it is known as sourcing sensor.

Pnp sensors are sometimes called “supply sensors,” because the power supply is positive at the output. Benefits of pnp versus npn. But what are the differences between them?

The Difference Is A Result Of The Internal Circuit Design And Type Of Transistors Used.


Without any load resistor : High and low levels of pnp and npn output signals are different. The selection of a pnp sensor relative to an npn sensor is determined by the nature of the circuit the device is to be used in.
