Optical Sensors are widely used in various industrial applications. photointerrupters, or sometimes referred to as slotted optical sensors, are a type of optical sensor capable of detecting the presence of an object based on it\'s interrupting a light beam as it trips across the sensor. The WF15-95B410 is a Slot Type Photointerrupter with Transistor Output, capable of detecting passing objects up to 5mm in diameter.

The WF15-95B410 performs its detection by generating a beam of light from its emitter diode, directed towards a total reflection prism which reflects the light against a slot in its face. As an object passes across the slot, it interrupts and blocks the light, preventing it from reaching the phototransistor at the other side. By monitoring the output of the phototransistor, one can determine the moment when an object has passed in front of the slot.

The main application field for the WF15-95B410 is in industrial automation and process control, where the presence of an object must be quickly detected and its rotational speed calculated. It is also used for automatic turnstile doors, security sliding gates or any other application which requires an efficient and safe detection mechanism. The working principle of the WF15-95B410 allows it to detect a passing object up to 5mm in diameter, regardless of whether it is a metal or non-metallic object. Apart from this, its small size and efficient design also make it suitable for a variety of applications, including machine vision systems, detecting the presence of a person in a dark environment.

The WF15-95B410 operates by providing a constant DC Voltage, typically 5V, to the LED emitter diode. When an object passes across the slot, the phototransistor receives no light and its output goes low, allowing a signal to be sent to the system. The integrated design of the unit also provides an easy setup, with no extra external components needed. In addition, the WF15-95B410 includes a built-in temperature compensation circuit, allowing it to maintain its performance even in high temperature environments.

In summary, the WF15-95B410 is a Slot Type Photointerrupter with Transistor Output, capable of detecting passing objects up to 5mm in diameter regardless of its type. Its small size and integrated design make it suitable for a variety of applications in industrial automation and process control. The WF15-95B410 also features a built-in temperature compensation circuit, allowing it to provide accurate and reliable readings even in high temperature environments.
