Optical sensors are a type of sensing device, which can detect a range of physical stimuli, such as light, motion, temperature, and pressure. Photoelectric, industrial, and other types of optical sensors are used in a wide range of applications. 70156-3138 is a type of optical sensor, which can detect light and motion. In this article, we will discuss its application field and working principle.

Application Field

70156-3138 is a popular and versatile optical sensor. It can be used in a variety of industrial and commercial applications, including HVAC (Heating, Ventilation, and Air Conditioning) control, security systems, automation, and process control. The sensor is also used in medical equipment, rail and mass transport systems, aerospace applications, and military applications. This is due to its fast response time and high reliability.

Working Principle

70156-3138 consists of two parts, a transmitter and a receiver. The transmitter is usually a light emitting diode (LED). The LED emits light which is detected by the receiver, which is usually a photodiode. When the light is disrupted, the photodiode detects the change in incoming light and produces an electrical signal in response. This electrical signal is then sent to a control unit, which in turn is used to control the processes. This is usually done through a relay switch.

In addition, the receiver is also capable of detecting motion and other changes in the environment. This is done by the detector changing its output voltage when exposed to a change in the environment. The output voltage can be used to control a variety of processes, such as the speed of a motor or the on/off state of a switch.

70156-3138 optical sensors are highly sensitive and reliable. They are able to detect even subtle changes in the environment and react appropriately. The sensors are powered by a standard 5V power supply and have a response time of less than 10 milliseconds. The sensors are also very efficient, consuming only 1mA of current. In addition, they are highly resistant to interference from other sources, such as radio frequency and electrostatic interference.

70156-3138 optical sensors are a reliable and cost-effective option for a variety of industrial and commercial applications. They are easy to install and are reliable in operation. The sensors are able to detect a range of physical stimuli and respond to them quickly and accurately. The sensors are also resistant to interference and have a long life span, making them an ideal choice for a variety of applications.
