Proximity Sensors – Types, Working Principle & Applications

Inductive Sensor Detects metallic objects only Works using a magnetic field When metal comes near, the magnetic field changes and the sensor detects it Range: Up to 50 mm Commonly used in industrial machines Capacitive Sensor Detects metallic and non-metallic objects (plastic, wood, liquid, etc.) Works by detecting changes in capacitance Suitable for detecting a wide variety of materials Range: Up to 50 mm Photoelectric Sensor Detects objects using light rays Works by emitting light and sensing reflection or interruption Can detect both metallic and non-metallic objects Range: Up to 1.5 meters Used in conveyor systems and counting applications Ultrasonic Sensor Works using ultrasonic (sound) waves Measures the time taken for the echo to return Detects objects regardless of color or transparency Range: Up to 10 meters Best for distance measurement and object avoidance 👉 Conclusion: Each proximity sensor type has a different working principle and application, making them suitable for specific industrial and automation needs. #ProximitySensor #InductiveSensor #CapacitiveSensor #PhotoelectricSensor #UltrasonicSensor #IndustrialAutomation #ElectricalEngineering #Instrumentation #Sensors #AutomationTechnology #Electronics #ControlSystem #Industry40 #EngineeringBasics
