Optical sensors are devices used to detect or measure light intensity or light in a given area. Phototransistors are one of the most common types of optical sensors that are used in a wide range of applications.

The SMD2440-002 optical sensor is a surface mount device (SMD) manufactured by Interlink Electronics. It is a high-performance, optically sensitive switch. The device consists of an infrared-responsive photo detector, an integrated amplifier, a quad amplifier, and a current sink. The device is hermetically sealed and sealed with epoxy. It has a 20x20mm outline with a total height of 2mm and a weight of only 2.2g. The device is used for sensing infrared or visible light sources.

Application Field

The SMD2440-002 is commonly used in industrial, automotive, aerospace, and consumer electronic applications. It is used for the control and measurement of lighting systems, such as light curtains, photodiode light bar controllers, laser beam line detectors, and much more. The device is also used in applications where the detection of very low levels of light is required, such as smoke detectors, fire alarms, and flame sensors. In addition, the device is used for applications such as safety gates and conveyor line detection. The device is also used in industrial robots for position sensing and data acquisition.

Working Principle

The SMD2440-002 operates on the same principle as other optical detectors. The device consists of two elements, an LED and a phototransistor. The LED is used to provide the light source for the phototransistor. When the LED is powered, it will emit visible or infrared light. When the phototransistor detects this light, it will convert the light energy into electrical current, which is then sent to the amplifier for further processing. The output from the amplifier is either an analog output (voltage) or a digital output (switch).

The SMD2440-002 can be used in a variety of applications. In industrial applications, the device is used for the control and measurement of lighting systems. In automotive applications, the device is used for the detection of fire alarms and smoke detectors. In aerospace applications, the device is used for the detection of low-level signals, such as flame sensors.

The SMD2440-002 is an ideal device for industrial, automotive, aerospace, and consumer applications. Its hermetically sealed construction ensures enhanced reliability and durability. Its integrated amplifier provides high-resolution control, and its fast response time and high sensitivity make it ideal for low-level signal detection. Its small size and low weight make it easy to install in even the most confined areas. The device is also cost-effective, making it an attractive solution for a wide range of applications.
