Product Name: Capacitive Proximity Switch Switch Appearance Type: Cylinder Type Capacitance Sensor Output Type: NPN NO (Normal Open) Diameter of Head: 18mm Detecting Distance: 1-10mm Detecting Object: Metal or Nonmetal Material Supply Voltage: DC 6-36V Current Output: 300mA Response Frequency: 100Hz Size: 7.5 x 4cm or 3" x 1.6" (LxMax. Dia) Material: Plastic, Alloy This component is commonly utilized in the automatic control industry for detection, control, and non-contact switching. When the proximity switch is near a target object, it emits a control signal. As a capacitive type proximity switch, it can detect not only conductors but also liquids and powders, including plastic, water, glass, oil, and more. It's widely employed in machinery, paper production, and light industries for station limiting, orientation counting, and speed trials. Package Contents: 1 x Capacitive Proximity Switch Only the above package content is included other products are not part of this offer.
