Product Description:
A Photoelectric Sensor is a type of sensor that detects the presence or absence of an object using a light transmitter and a receiver. One popular variation of this sensor is the Infrared Light Sensor, which utilizes infrared light to sense objects. The Photoelectric Sensors are widely used in industrial automation applications due to their reliability and versatility.
What is a photoelectric sensor?
A photoelectric sensor is a type of position-sensing device widely used in industrial automation to detect the presence, absence, or distance of an object using a beam of light. It operates based on the principle of light transmission and reception. The sensor system primarily consists of two main components: an Emitter, which produces a beam of light (typically infrared or visible), and a Receiver, which detects the presence or absence of this light.

Applications:
KRONZ Photoelectric Sensors are versatile devices that can be used in a wide range of product application occasions and scenarios. These sensors, originating from Guangdong, China, are CE certified and offer a sensing distance of 20-300mm with a response time of 1ms.
How are photoelectric sensors used in industrial automation?
When the emitted light travels from the Emitter to the Receiver without interruption, the sensor remains in a default state. However, when an object passes through or reflects the light beam, it disrupts or redirects the light path. This change is detected by the Receiver, which converts the variation in received light intensity into an electrical signal. This signal is then used to trigger a response, such as activating a machine, stopping a conveyor belt, or counting parts on a production line.
