Optical sensors are devices that can detect and measure light, generally in the form of visible, infrared (IR) or ultraviolet (UV) light. They allow machines to detect and monitor objects in their environment, and play a crucial role in automated processes. The 70156-1821 is a photoelectric industrial sensor that combines both the detection of discrete objects in the projected light field and the measurement of analog levels of light in the sensing field.

Application Field

The 70156-1821 industrial sensor is designed to provide reliable detection of discrete objects in a production environment. Common applications for this sensor include detecting items on a conveyor belt, detecting objects in an automated process, and detecting the presence of a human or machine in a production area. This sensor is also used to detect the levels of light in a factory, warehouse, or other industrial setting.

The 70156-1821 sensor is also used in a variety of safety applications, such as bicycle and pedestrian safety, machine or robotic monitoring, and in self-driving cars. It can be used to detect the presence of objects in a hazardous environment and help prevent accidents by alerting operators or other safety systems. This sensor is an important component in systems that are designed to automatically detect and manage safety risks.

Working Principle

The 70156-1821 sensor is a type of photoelectric sensor, which consists of an emitter, receiver, and amplifier. The emitter projects light in the form of infrared (IR), UV, or visible light, which is detected by the receiver. The receiver detects the difference between the projected light and the ambient light in the sensing area. This difference is amplified and converted into an electrical signal, thus creating an output from the sensor. Depending on the application, this output can either detect the presence of a discrete object or measure the level of light in the sensing area.

The 70156-1821 sensor can be used in a variety of applications where the detection of discrete objects or the measurement of light levels are necessary. This sensor is a reliable and cost-effective option for environments where accuracy and fast response times are essential. The sensor is easy to install and requires minimal maintenance, which makes it an ideal solution for industrial settings.
