The 70156-1172 optical sensor, also known as a photoelectric sensor, is an industrial-grade device designed to measure the presence or absence of an object. It is capable of precisely detecting objects located across a wide range of distances with angular divergences as low as 10°. As a result, this optical sensor offers superior reliability and repeatability than its predecessors.

In its most basic form, the 70156-1172 optical sensor consists of an emitter and a receiver. The emitter consists of a light-emitting diode (LED) which produces a visible beam of light. This beam is then directed at a special sensing surface, such as a mirror or a photodiode. When an object passes through the beam, the receiver captures the reflected light, providing functionality similar to that of a basic photocell.

The 70156-1172 optical sensor is capable of detecting objects within a wide range of distances, from inches to yards, with resolution as low as 0.001 inches. This makes it ideal for applications in the industrial field, such as quality assurance, monitoring and automation. The ability to detect extremely small objects is especially advantageous for applications requiring sub-millimeter resolution. For example, the optical sensor can be used in machining and assembly processes to detect the accurate placement of parts.

In addition to its accuracy and precision, the 70156-1172 optical sensor features a number of configurable operating parameters. This includes adjustable time delays for pulse width, response time, and maximum operating range. Additionally, power supply and output switching methods can be configured to maximize performance and enhance readability.

The working principle of the 70156-1172 optical sensor is quite simple. When the LED is illuminated, the light beam is projected towards the sensing surface. When an object passes close to or through the beam, the reflective light is captured by the receiver, which generates an electrical signal. This electrical signal is then processed and sent to an output device. Depending on the type of output selected, this signal can be used to trigger an on/off signal, an analog output, or a digital output.

In conclusion, the 70156-1172 optical sensor is a dependable and accurate device that offers superior performance over conventional photoelectric sensors. It is designed to detect small objects located at long distances with angular divergences as low as 10°. This makes it ideal for industrial applications requiring precise detection and measurement capabilities. Additionally, the configurable parameters allow users to optimize the sensor’s performance, while the simple working principle provides reliable results.
