Optical Sensors - Photoelectric, Industrial

Optical sensors are devices that emit or detect light to interpret and analyze the surrounding environment. Common types of optical sensors consist of photoelectric sensors, industrial sensors, and other specialized sensors. The 70156-1696 model is one such specialized device that is utilized in a variety of settings for different applications. This article examines the features of the 70156-1696 optical sensor, exploring its application field and working principle.

Design and Components

The 70156-1696 is designed to detect the absence of a beam of light to ensure the accuracy of sensors used in manufacturing processes. It is equipped with a total of seven components, including a laser diode, amplifier board, amplifier, LED indicator, optical head, and two antennae. The laser diode is constructed of quartz and has a wavelength of 745nm, visible to the human eye. The amplifier board amplifies and amplifies the output of the laser diode and sends it to the amplifier. The amplifier amplifies the signal before outputting it to the LED indicator. The output signal from the LED indicator is sent to the optical head and then to the two antennae for transmission.

Features

This sensor has a number of features that make it suitable for a wide range of applications. Its laser diode has a wide emission angle, allowing it to detect a beam of light at greater distances. It is also capable of detecting motion in complete darkness, making it ideal for night operations. Additionally, its high sensitivity can detect even minute changes in signal intensity.The sensor is also designed to be energy efficient. It does not require a large amount of power to operate, making it suitable for batteries or solar power applications. It is also designed to be resistant to strong electromagnetic interference, allowing it to function even in harsh environmental conditions.

Applications and Working Principle

The 70156-1696 optical sensor is used in a variety of settings. It is commonly utilized in industrial applications such as robotics, packaging, and print manufacturing. Additionally, it is used for medical purposes, to monitor the health of patients through the detection of pulse, temperature, and other vital signs.In operation, the sensor sends out a beam of light from the laser diode. If the beam is not blocked, the LED indicator remains off. However, if the beam is blocked, the LED indicator turns on. The LED indicator then sends a signal to the amplifier, which amplifies the signal and sends it to the optical head. Finally, the signal is transmitted through the two antennae. This process allows the sensor to detect the absence of a beam of light, which is useful for a number of applications.

Conclusion

The 70156-1696 optical sensor is a specialized device that is utilized in a wide variety of industrial and medical applications. It is able to detect the absence of a beam of light and is designed to be energy efficient. Additionally, its laser diode has a wide emission angle, making it suitable for long-distance detection. Its features and design make it a suitable choice for a number of applications.
