Omron Proximity Sensors – Inductive & Capacitive Sensors

Types of Omron Proximity Sensors

Omron proximity sensors are available in inductive and capacitive sensing types for detecting different target materials without physical contact. The suitable sensor depends on the target material, required sensing distance, mounting arrangement, and output configuration.

Omron Inductive Proximity Sensors

Omron inductive proximity sensors detect metal objects using an electromagnetic sensing field without requiring physical contact. They are commonly used for metal part detection, position confirmation, counting, and machine movement monitoring. Different models are available with various sensing distances, body sizes, and PNP or NPN output configurations.

Omron Capacitive Proximity Sensors

Omron capacitive proximity sensors can detect suitable metallic and non-metallic targets, including materials such as plastic, glass, liquids, and powders. They are used for object and level detection applications where inductive sensing alone is not suitable. Available configurations vary by sensing distance, mounting method, output type, and model.

Applications of Omron Proximity Sensors

Omron proximity sensors are used in industrial machines to detect objects, confirm component positions, monitor movement, and identify material presence without physical contact. Inductive and capacitive models support different detection requirements depending on the target material and application.

• Metal object detection in conveyor systems
• Position and presence detection in industrial machines
• Part detection in packaging and labeling equipment
• Level detection of suitable liquids and materials
• Component detection in material handling systems
• Position confirmation in automated assembly equipment
• Machine movement and end-position detection

How to Select an Omron Proximity Sensor

Select an Omron proximity sensor by matching the target material, sensing distance, sensor size, output configuration, power supply, and installation conditions with the requirements of the machine or application.

• Sensing Type: Choose an inductive proximity sensor for metal targets or a capacitive proximity sensor when suitable metallic or non-metallic materials need to be detected.
• Sensor Size: Select a suitable body size such as M8, M12, or M18 according to the available mounting space and required sensing characteristics.
• Output Type: Choose a PNP or NPN proximity sensor according to the PLC or controller input configuration, and verify whether NO or NC switching is required.
• Sensing Distance: Check the required distance between the sensor and target. Long-range proximity sensor models can be considered where a greater detection distance is required.
• Power Supply: Verify the operating voltage of the selected model and match it with the machine control system, including applicable DC or AC configurations.
• Operating Environment: Consider temperature, mounting conditions, target material, surrounding metal, and environmental exposure. Specialized models may be required for high-temperature or other demanding applications.
