Round type through beam photoelectric sensor is used to detect the presence or absence of an object by transmitting a light beam from one side of the detection area to a receiver on the opposite side. Infrared photo electric switch can distinguish opaque reflective objects, with 5m detection distance and DC 12-24V power supply, less susceptible to interference.

Tips: How to choose the right photoelectric sensor for my application?

There are several key factors to consider when choosing the right photoelectric sensor:

Sensing distance: Determine the distance between the photoelectric sensor and the object to be detected. Choose a sensor with a sensing range that can easily cover this distance.
Environment: Evaluate the environmental conditions in which the photoelectric sensor will be installed. Factors such as ambient light, dust, humidity, and temperature can affect sensor performance. Choose a sensor with the appropriate environmental rating for your application (such as an IP rating for dust and water resistance).
Output type: Decide whether you need a sensor with a digital (on/off) output or an analog output. Digital sensors provide a simple indication of the presence of an object, while analog photoelectric sensors provide more detailed information about the object's distance or reflectivity.
Response time: Consider how quickly an object moves through the photo sensor detection area and the response time required for your application.
Mounting options: Determine how you plan to mount the photoelectric sensor, such as through-beam, retro-reflective, or diffuse. Depending on your application setup, different installation options provide varying levels of simplicity and flexibility.
