70156-3700

Optical sensors are sensing devices that utilize light in order to detect the presence of an object. The optical sensor acts as a switch, controlling the different types of industrial applications. A type of optical sensor that operates as a switch is the 70156-3700. This article will explain it further, including its application field and working principle.

Application Field

The 70156-3700 is a universal optical sensor, applicable in many industrial applications. It can be used to detect objects made of various materials, such as wood, metal, stone, plastic, and foam. Moreover, it is able to respond to varying light conditions and temperature levels, which makes it suitable for operation in a wide range of environmental conditions. Because of its ability to detect various objects accurately, the 70156-3700 is ideally suited for applications that involve non-contact inspection, such as automated production lines, robotics, and 3D printing. In addition, it is suitable for automation operations that require accuracy, precision, and reliability such as CNC (Computer Numerical Control) machining, control system applications, and general industrial automation.

Working Principle

The 70156-3700 employs a small emitter and detector to sense objects. The emitter emits a focused light beam, which reflects off the object and into the detector. Depending on the material of the object, the amount of light reflected back will be different; this reflected light is then processed by a microcontroller. If the amount of light reflected back is within the predetermined limits, the optical sensor will output a "strong signal" that triggers, or activates the desired output. However, if the amount of light reflected is outside the predetermined limits, the sensor will output a "weak signal". Thus, a strong signal is generated only when an object is detected within the optimal sensing area and the microcontroller is able to differentiate between a strong and a weak signal.

The 70156-3700 optical sensor is ideal for industrial operations where accuracy, precision, and reliability are essential. Its ability to sense various materials, operate in a wide range of environmental conditions, and process signals quickly make it the perfect solution for a wide range of applications.
