Optical sensors are devices that use light to measure physical parameters, and the 70156-3797 sensor is no exception. It\'s a photoelectric, industrial type with 5 different sensing functions available - background suppression, light operate, retro-reflective, polarised retro-reflective and diffuse, and has a modular design for easy and fast setup. Here, we\'ll be looking into application field and working principle of the 70156-3797 sensor.

The 70156-3797 sensor is designed for use in a range of applications, including automation, robotics, material handling systems, printing device, machine vision systems, and textiles. It works well in applications that require accurate, repeatable and high-speed detection and with its two fibre-optic models, it can be used in very harsh and hazardous environments. The 70156-3797 has a dual stage thermoplastic housing with a compact design, making it suitable for difficult and restricted locations as well as for easy integration into existing systems.

The 70156-3797 can sense object up to 11 metres away, with a minimum object detection size of 2.5mm. It has a large variety of operating modes, such as fixed and adjustable sensitivity, adjustable beam width, mode for precise object orientation and height, single-pulse modes and pulse-length control. This allows users to easily configure the sensor to best suit their applications. The sensor also comes with warning and diagnostics LEDs, enabling users to quickly diagnose any problems with the device.

Now let’s move on to the working principle of the 70156-3797 sensor. It is designed to have light emitted from an LED source, which is sent out in a visible beam to detect objects in its range. When a reflected light is received by the sensor, it is then processed by the sensor controller and a corresponding signal is then sent to a connected device to indicate the presence, absence or intensity of the object being detected. The variuos operating modes of the 70156-3797 allows for more extended features such as high-end applications that require precise object detection, object size and orientation detection, as well as pulse-length control.

At the same time, the 70156-3797 sensor also has a dynamic background suppression mode, which allows the device to detect objects in a moving environment and variable background. The background suppression mode works by first comparing the current background scene to a value saved in memory. The sensor then detects changes in light intensity and subsequently outputs a signal according to the changes.

In addition, the 70156-3797 has an automatic amplifier and threshold adjustment feature. This allows users to set the threshold and saturation outputs of the device, and the sensor automatically adjusts its emission to optimize the sensor’s performance to different object sizes and parameters. This makes the device suitable for use in different applications without needing manual configuration to reach the desired results.

Overall, the 70156-3797 sensor is a great choice for industrial applications that require accurate, repeatable and high-speed detection. The device offers a range of sensing functions, with variable detection and threshold outputs, allowing users to set up their system quickly and efficiently. The dynamic background suppression mode also ensures the device can be used in different applications with varying backgrounds, making this a highly versatile and dependable photoelectric, industrial sensor.
