Optical sensors are widely used in diverse applications in fields such as medicine, security, robotics, industrial automation, and agriculture. One type of optical sensor is the phototransistor, which can convert light into electrical signals or convert electrical signals into light. The OP801WSL is one model of phototransistor designed specifically to be used in industrial applications.

The OP801WSL is a photosensitive device based on NPN Silicon phototransistor that is sensitive to visible and infrared light. It has a small package size, narrow spectral response, and high sensitivity, making it an ideal choice for use in long or low light level operations. The device is designed to be easy to use and install, as it requires only a few pins to operate. It is also highly reliable and has a wide working temperature range of -40 to +85°C.

The OP801WSL offers excellent switching performance with high gain and fast response time, great immunity to noise, and low on-resistance. It is suitable for linear and switching applications, such as controlling crane operation and proximity sensing. It can also be used in applications such as analog measurement and light control.

The working principle of the OP801WSL is quite simple. When light is applied to the phototransistor, the photocurrent generated lowers the level of current flowing from the collector to the emitter. This result in a lower voltage at the collector, which can be measured and used to drive other circuits. The amount of current and voltage changes depending on the amount of light that is applied.

The OP801WSL has a variety of features that make it a great choice for industrial applications. Some of these features include low on-resistance for high sensitivity, an instantaneous response time of less than 1 μs, and a wide working temperature range of -40 to +85°C. It also offers a great immunity to noise and excellent switching performance.

To summarize, the OP801WSL is a photosensitive device based on NPN Silicon phototransistor. It is designed to be used in industrial applications and has a small package size, narrow spectral response, high sensitivity, and fast response time. It is suitable for linear and switching applications, such as controlling crane operation and proximity sensing, as well as for analog measurement and light control. The working principle is quite simple, where the photocurrent generated from the phototransistor affects the current flow and voltage. The OP801WSL is an excellent choice for industrial applications due to its low on-resistance, fast response time, wide working temperature range, and great immunity to noise.
