Product type
Photoelectric sensors are devices that use light to detect the presence or absence of an object. They work by emitting a beam of light, typically infrared, and measuring the amount of light that is reflected back. Depending on the configuration, they can operate in different modes such as through-beam, retro-reflective, or diffuse reflection. These sensors are widely used in automation systems to enhance operational efficiency and safety.
| Sensing range | Up to 10 meters |
| Output type | NPN or PNP |
| Supply voltage | 10 to 30 VDC |
| Response time | 1 ms to 5 ms |
| Environmental rating | IP65 or higher |
| Operating temperature | -25°C to 70°C |
When selecting a photoelectric sensor, consider the sensing range and the type of output required for your specific application. It's important to specify the environmental conditions, such as temperature and exposure to dust or moisture, to ensure compatibility. Additionally, inquire about certifications and compliance with industry standards, as well as the quantity needed for your project to receive an accurate quote.
