Product type
Photoelectric sensors are devices that use light to detect the presence or absence of an object. They typically consist of a light source, a receiver, and a processing unit. When the light beam is interrupted by an object, the sensor detects the change and sends a signal to the control system. These sensors are commonly made from durable materials such as plastic and metal to withstand various industrial environments.
| Detection range | Up to 10 meters |
| Supply voltage | 10 to 30 VDC |
| Output type | NPN or PNP |
| Response time | 1 ms to 5 ms |
| Operating temperature | -25°C to +70°C |
| Housing material | Plastic or metal |
When selecting a photoelectric sensor, consider the detection range and the type of output required for your application. It's important to specify the supply voltage and the environmental conditions, such as temperature and humidity, where the sensor will operate. Additionally, check for necessary certifications that may be required for your industry, and determine the quantity needed for your project to receive accurate quotes.

There are several types, including through-beam, retro-reflective, and diffuse sensors.
Installation typically involves mounting the sensor at the appropriate height and aligning it with the object to be detected.
Most photoelectric sensors can last several years, depending on usage and environmental conditions.
Yes, but ensure to choose models rated for outdoor use to withstand weather conditions.
Common output types include NPN, PNP, and analog outputs.
Generally, they require minimal maintenance, but regular cleaning of the lens may be necessary.
