Product Name: Capacitive Proximity Switch Switch Appearance Type: Cylinder Type Sensor Type: Capacitance Sensor Output Type: NPN NO (Normally Open) Head Diameter: 18mm Detecting Distance: 1-10mm Detecting Object: Metal or Nonmetal Materials Supply Voltage: DC 6-36V Current Output: 300mA Response Frequency: 100Hz Size: 7.5 x 4cm / 3" x 1.6" (L x Max. Dia) Material: Plastic, Alloy This component is widely used in the automatic control industry for detection, control, and non-contact switching. When the proximity switch is close to a target object, it sends out a control signal. As a capacitive type proximity switch, it can detect not only conductive materials but also non-conductive materials such as liquids, powders, plastic, water, glass, and oil. It is commonly used in machinery, paper manufacturing, and light industry applications for position limiting, object detection, counting, and speed monitoring. Package Contents: 1 x Capacitive Proximity Switch Note: The package includes only the items listed above. Other products are not included. Note: Lighting and display settings may cause slight color differences between the image and the actual item. Measurement error is +/- 1-3cm.
