Product type
Photoelectric sensors are devices that use light to detect the presence or absence of an object, or to measure distance. They typically consist of a light emitter, often a laser or LED, and a receiver that detects the light reflected from an object. These sensors are widely used in industrial automation for tasks such as counting, positioning, and safety applications.
| Detection range | Up to 10 meters |
| Output type | NPN, PNP, or analog |
| Operating voltage | 10 to 30 VDC |
| Response time | 1 ms to 10 ms |
| Housing material | Plastic or metal |
| Environmental rating | IP65 to IP69K |
When choosing photoelectric sensors, consider the detection range and the type of output required for your application. It's important to specify the environmental conditions, such as exposure to dust or moisture, to ensure the sensor's durability. Additionally, check for any necessary certifications for safety and compliance, and determine the quantity needed for your project to obtain accurate quotes.
