Optical Sensors have a wide range of applications in many industrial and commercial applications. In this article, we will look at the industrial applications and working principle of the 70156-4396 sensor. This is a Photoelectric Sensor manufactured by the American company Omron, which is an industry leader in the sensing and control technology.

Introduction to Photoelectric Sensors

Photoelectric sensors are used to detect the presence and position of objects in industrial and commercial applications. They can be used to detect the presence and motion of objects in factory automation, manufacturing, packaging, and material handling. Photoelectric sensors consist of two main components: a light source and a receiver. The light source emits a light beam, typically in the form of a visible beam, and is typically infrared or ultraviolet in the form of a visible light beam.

When the object passes the light source, the light beam is interrupted, resulting in a change in the electrical output of the receiver. This change is then detected and interpreted by a logic circuit to give the desired output. The size, type, and cutoff distance of the light beam dictate the sensitivity of the sensor.

Application and Working Principle of the 70156-4396 Sensor

The 70156-4396 Photoelectric Sensor from Omron is a high-precision device that offers an output with both “dark” and “light” response times of less than one millisecond. This makes it particularly suitable for factory automation environments, where time is of the utmost importance. It is designed for reliable sensing of small objects at a short distance. The device comes in a variety of sizes and shapes, allowing it to be fitted in a variety of industrial locations.

The working principle of this device is relatively simple. The device can be set to detect any object that interrupts its light source, which can be configured to have either a “dark” response (the device detects a change in light when an object is detected) or a “light” response (the device detects a change in darkness when an object is detected). A variety of electronic controls are mounted on the device to adjust the sensitivity and response time of the device to fit the application.

The device can be configured with a range of different specifications, including distance, focus spot, beam spread, and sensing angle, to tailor it to the particular application. For example, if you wanted the device to detect objects at a longer distance, you could decrease the sensitivity and increase the beam spread, while if you wanted the device to detect a specific size of object, you could adjust the focus spot and sensing angle, or use a combination of both.

Conclusion

The 70156-4396 Photoelectric Sensor from Omron is a high-precision device that offers both “dark” and “light” response times of less than one millisecond. This makes it ideal for factory automation and other industrial applications. The device is configurable, allowing the user to adjust the sensitivity and response time to suit the particular application. The device is a simple but powerful tool, offering excellent reliability and versatility for sensing small objects at a short distance.
