Optical Sensors are used to sense various parameters, such as presence, absence, position, and color. The 70156-3058 is a Photoelectric type of industrial Optical Sensor. This article will cover the application field and working principles of the 70156-3058, enabling readers to get a better understanding of how this type of Optical Sensor functions.

The 70156-3058 Optical Sensor is typically used for industrial applications like safety limit switches, sensors, and light obstruction. It is also suitable for use in office automation, office equipment, machine tools, and home appliance applications. The Sensor consists of an LED, a phototransistor, and related optical elements. When an obstacle is present in the sensing range of the Sensor, light emitted from the LED is blocked, and the phototransistor does not respond, thus switching the output of the Sensor to "OFF".

The working principle of the 70156-3058 Optical Sensor is based on a basic optical sensing technique. The LED emits light, which is then picked up by the phototransistor. When an obstacle or some other kind of object is present in the sensing range of the Sensor, the light is blocked, and the phototransistor does not respond. Therefore, the output of the Sensor is switched to "OFF". Also, the 70156-3058 is equipped with an "OFF shutter", which prevents the LED from being over-driven in cases where light is being blocked for an extended period of time. This helps to extend the life of the Sensor and keep it from being damaged.

The 70156-3058 Optical Sensor is available in two different models: a "direct drive" type and a "single-ended" type. The "direct drive" model has an LED that is directly wired to the phototransistor, meaning that the output of the Sensor is directly affected by the amount of light received by the phototransistor. The "single-ended" model, on the other hand, has a separate light source for each phototransistor, meaning that the output of the Sensor is affected by the total amount of light received, even if one or more phototransistors do not receive any light.

The 70156-3058 Optical Sensor also comes with manual control buttons, which allow the user to manually adjust the sensitivity of the sensor. This feature can be used to adjust the amount of light that the Sensor is exposed to, thus increasing or decreasing the sensitivity of the Sensor accordingly. This allows the user to customize the performance of the Sensor to suit their own needs.

The 70156-3058 Optical Sensor is a reliable and versatile Sensor that is suitable for a variety of applications. It is easy to install and maintain, and provides superior performance in a wide range of lighting conditions. This makes it an ideal choice for a variety of applications, from safety limit switches to light obstruction. With its reliable and accurate performance, the 70156-3058 Optical Sensor is well-suited to any industrial or office automation application.
