Product type
Capacitive proximity sensors are devices that detect the presence of objects without physical contact. They work by measuring changes in capacitance caused by the proximity of an object, typically non-metallic materials such as plastics, liquids, or granular substances. These sensors are widely used in industrial automation for applications such as object detection, level sensing, and material handling.
| Detection Range | Up to 20 mm |
| Operating Voltage | 10 to 30 VDC |
| Output Type | NPN or PNP |
| Housing Material | Plastic or metal |
| Protection Rating | IP65 or higher |
| Temperature Range | -25 to 70 degrees Celsius |
When selecting a capacitive proximity sensor, consider the detection range and the types of materials you will be sensing. Specify the required output type (NPN or PNP) based on your control system. Additionally, check for the protection rating to ensure suitability for your environment, especially in harsh conditions. Certifications for safety and compliance may also be crucial depending on your industry standards.
