Optical sensors are an important and widely used type of sensors, especially in industrial and automotive applications. This type of sensor is used to detect the presence or absence of light, measure light intensity, and determine the wavelength of light. Among these sensors, the 70156-3560 Photoelectric Sensor is a widely used industrial-grade optical sensor capable of detecting light in various frequencies. In this article, we’ll discuss the application field and working principle of the 70156-3560 Photoelectric Sensor.

The 70156-3560 is a programmable Photoelectric Sensor that can be used in many industrial applications, such as machine automation, automatic sorting and counting, packing and bottling, robotics, and traffic control. It can detect changes in light within a certain range and provide a signal accordingly. The sensor can detect infrared light in the range of 830nm to 1060nm, and visible light from 400nm to 700nm. It is also available in three versions: the standard (70156-3560), the with-oc version (F7156-3560), and the unlit version (E7156-3560).

The 70156-3560 Photoelectric Sensor works on the principle of scattered light detection. It has a light emitter (LED) and a receiver (photodiode). When the LED is energized, it emits light, which falls on the object. When the object reflects the light back, it is detected by the photodiode. The sensor then processes the intensity of the received light and compares it with the minimum intensity required for detection. If the received light intensity is more than the minimum detectable level, the sensor then sends a signal to indicate the presence of an object.

In addition to its scattered light detection principle, the 70156-3560 Sensor is characterized by several features that make it suitable for industrial use. It has an operating temperature range of -55 to +80 degree Celsius and is available with water and oil-resistant connectors, which makes it suitable for use in harsh environments. The sensor has a wide operating voltage range, from 12 to 24 VDC, and a 5metre cable. It has an integrated amplifier, which makes it able to detect objects up to 4 metres away with a maximum of 4 objects in a single zone.

The 70156-3560 has a detection accuracy of ±10% at a distance of 1 metre, and an operating frequency of 1kHz. It also features selectable normally open/normally closed circuits, which allows the user to choose either of the two depending on the application. Moreover, the sensor has a fail-safe function, which keeps the output signal stable when light is interrupted. This is especially useful in applications such as traffic control, where there is a need to keep a continuous signal even in the event of power failure.

In conclusion, the 70156-3560 Photoelectric Sensor is an industrial-grade optical sensor that can detect the presence or absence of light, and it is widely used in industrial applications. It operates on the principle of scattered light detection and is characterized by features such as a wide operating voltage range, fail-safe function, and selectable normally open/normally closed circuits. It is available in three versions and has a detection accuracy of ±10% at a distance of 1 metre.
