PROXIMITY SENSOR

A proximity sensor is a type of sensor that detects the presence of nearby objects without any physical contact. NPN refers to the type of transistor used in the output configuration of the sensor.

Proximity sensors are commonly used in automation, robotics, manufacturing, and safety systems to detect objects at a short range. They work on different principles such as inductive, capacitive, ultrasonic, or infrared.

Wiring of NPN Proximity Sensors

• Brown wire (VCC): Power supply
• Blue wire (GND): Ground connection.
• Black wire (Output): The signal output, which is pulled to ground when an object is detected.

Applications of NPN Proximity Sensors:

• Automated assembly lines: To detect the presence of metal parts.
• Robotics: For obstacle detection or end-of-arm positioning.
• Conveyor systems: To detect objects passing by without contact.
