The WF2-95B416 is an optical sensor that falls within the general type known as photointerrupters, or slot type, with transistor output. It is a compact device within an industry-standard package, aimed at providing reliable detection of objects in narrow spaces. These sensors are generally used in industrial, or other mechanical applications.

The WF2-95B416 operates by detecting either interruption or presence of an object passing through the narrow slot, or opening, in the device. This slot is the window through which light is emitted from the infrared-emitting diode - or IRED - of the device. The light then passes through to a phototransistor. When the light is interrupted by an object, or when an object is sensed in the presence of the light, the phototransistor is triggered, and the corresponding electronic output signal is triggered.

The device contains two separate optical slots, both of which can be independently configured for either NPN or PNP output operation modes. Each slot is programmed with its own discriminator level, or intensity, thus allowing for faster response times and improved accuracy. And both slots can be software-configured to operate in either ‘normal’ (all objects in the slot are sensed) or ‘inverted’ (only objects that are in the presence of the slot are sensed) sensing mode.

Besides the two separate slots, the WF2-95B416 has two additional features. One is the built-in voltage regulator, which allows for precise and stable voltage supply for both the IREDs and the phototransistor. This feature also increases the overall reliability and accuracy of the device. The other is a wide tolerance of ambient light levels, which allows the device to detect objects in both bright and dark surroundings.

The WF2-95B416 is specifically designed for use in tight spaces and harsh environments. It can detect objects at a distance of up to 1.8 mm, and can withstand high-vibration and shock loads. The device is also protected against static discharge and transients. It can operate in a wide temperature range, and is also resistant to dirt, oils, condensation and dust.

The combination of features such as low-cost, small size, reliable performance, wide range of operating temperatures, high-voltage tolerance, and superior durability, make the WF2-95B416 an attractive device for a wide range of applications. Its main use is in automation processes, where it is used to detect the presence or interruption of objects, or to sense objects in tight places. It can also be used in machine control systems, motion control systems, and motor and actuator control systems. The device can also be used in manufacturing and conveyor systems, for sensing objects that pass through an opening.

In conclusion, the WF2-95B 416 is an advanced photointerrupter that is capable of reliable and accurate detection of objects. It has many features that make it suitable for both industrial and commercial applications. Its features include small size, high-voltage tolerance, low-cost and wide temperature range, which make it attractive for use in a wide range of applications.
