Optical sensors are used to detect electromagnetic radiation levels. Photodiodes are a type of optocoupler which is a small electronic device used to detect the presence of light. The SD200-11-21-241 is an optocoupler specifically designed for use in industrial applications. It is a type of hermetically sealed photodiode that is able to detect both visible and infrared light.

The SD200-11-21-241 is a two-wire device that operates on a voltage range of 2.5 to 16 volts. It is also a switching device, meaning it can be used as an input or output control switch. The device consists of five components including the main body, a lens, a photodiode, a resistor and a filter. In order to switch on the device, the bias voltage has to be below 3.15 volts. Once the bias voltage drops to 2.4 volts, the device will turn off. The lens of the device can be adjusted to focus light and control the amount of light that passes through it.

The working principle of the SD200-11-21-241 is based on the photovoltaic effect. When exposed to light, a photodiode generates a small voltage. This voltage is then amplified and used to control the switching of the device. When the bias voltage is high enough the device will remain in the “on” state. However, when the voltage drops below a certain threshold, the device will switch off, turning off the output signal. The resistor and filter help to regulate the voltage.

The SD200-11-21-241 has applications in a wide range of industries, including automotive, robotics, and industrial automation systems. It has been designed specifically for use in industrial applications as it offers superior isolation, noise immunity, long life, and high reliability. It is also used in medical imaging applications, such as computed tomography (CT) and magnetic resonance imaging (MRI). The device is also able to detect very faint levels of visible and infrared light and is therefore suitable for applications such as infrared imaging and night vision.

The SD200-11-21-241 is a hermetically sealed optocoupler device that is designed for use in industrial applications. It utilizes the photovoltaic effect to generate a voltage from exposed light which is then used to control the device switching. The SD200-11-21-241 offers superior isolation, noise immunity, long life, and high reliability and has a wide range of applications, including automotive, robotics, industrial automation, and medical imaging.
