LM18 Analog Inductive Proximity Sensor

The LM18 Analog Inductive Proximity Sensor is used for detecting metallic objects by utilizing inductive technology. This sensor provides an analog output that is proportional to the distance of a metal object from the sensor. It is commonly used in industrial automation, robotics, and metal detection applications.

Applications:

• Metal detection in automation systems
• Robotics for obstacle detection
• Industrial machinery for presence detection
• Proximity sensing for safety and control systems

Key Features:

• Analog output for distance measurement
• Sensitive to metals
• Long detection range
• Simple wiring and installation
• High reliability in industrial environments

Pinout Description:

• VCC: Power supply (5V to 24V)
• GND: Ground
• OUT: Analog output (corresponding to the detection distance of the metal object)

Sample Working Code for Arduino:

// LM18 Analog Inductive Proximity Sensor Example

int sensorPin = A0;  // Pin for reading the analog output of the LM18 sensor
int sensorValue = 0;  // Variable to store the sensor reading

void setup() {
  Serial.begin(9600);  // Start serial communication
}

void loop() {
  sensorValue = analogRead(sensorPin);  // Read the analog value from the sensor
  Serial.print("Sensor Value: ");
  Serial.println(sensorValue);  // Print the sensor value to the Serial Monitor
  delay(500);  // Delay for half a second before the next reading
}
