Optical Sensors - Photoelectric, Industrial

70156-4197 is a two-wire device developed to use in industrial applications as an optical sensor. It is based on the principle of photoelectric sensing using a laser beam to detect an object or motion. It works by sending a laser beam out through an optical lens and then detecting any reflections of the beam back to the lens. When the beam is reflected back, it activates an alarm, or triggers a response.

The 70156-4197 is able to detect low levels of light well and has a high sensitivity to motion. It is also able to work in adverse weather conditions, ranging from -20 to +50 degrees Celsius. This optical sensor is also resistant to vibration and shock, making it suitable for industrial applications that involve moving parts or extreme conditions. It is also relatively low-cost and is easy to install and maintain for long-term use.

The 70156-4197 can be used in a variety of industrial applications including monitoring the position of a mechanical part, detecting level changes in liquids, and detecting the presence of a foreign object in a restricted area. It is effective in challenging environments, such as foggy, dusty or smoke-filled conditions, where other sensors are not able to provide reliable data. This makes it ideal for applications in the automotive, aerospace, military, and mining industries.

The working principle of the 70156-4197 is based on the photoelectric effect. When a light is shone onto a metal surface, a voltage is created due to the interaction of the electrons in the metal and the light. The 70156-4197 takes advantage of this effect by generating a laser beam and then detecting the reflections of the beam on the metal surface. This produces an electronic signal when the beam is reflected back to the lens, which is then used to trigger an alarm or response.

The 70156-4197 is a reliable and cost-effective solution for industrial applications that need to detect objects or motion in challenging environments. Its use of the photoelectric effect to detect the reflection of the light beam makes it very sensitive and able to detect low levels of light in extreme conditions. This makes it an effective replacement for more expensive and complicated sensing systems, while still providing accurate sensing capabilities.
