Optical Sensors - Phototransistors
The SFH 3400-Z is an infrared-sensitive field effect transistor (FET) developed by Siemens Semiconductors. It is designed as an effective replacement for phototransistors in applications that involve the detection of light intensity, such as light-activated switching, alarm systems and infrared light barrier systems. This article will focus on the SFH 3400-Z application field and working principle.
Applications
The SFH 3400-Z can be used in a variety of applications where a compact, sensitive and reliable detector is required. These applications include;
- Infrared light barriers
- Object detection
- Level sensors
- Light-activated switching
- Alarm systems
- Presence detectors
The SFH 3400-Z is also suitable for use in applications involving light measurement where traditional phototransistors fail to provide reliable results. As a result, the SFH 3400-Z is a highly versatile and reliable detector which is suited to a variety of applications.
Working Principle
The SFH 3400-Z is a field effect transistor (FET). As such, it is sensitive to light rather than electric current and is connected to a basic amplifier circuit. When light falls on the detector, it causes a change in the electric field which is detected by the FET chip. This change in electric field is amplified by the amplifier circuit and can then be used to trigger a response.
The SFH 3400-Z is sensitive to light in the visible and infrared spectrum. This means that it can be used to detect objects, presence, motion or light intensity changes in application. As light falls on the detector, the electric field changes and can be used to trigger a response depending on the design of the circuit.
Conclusion
The SFH 3400-Z is a highly versatile and reliable detector which can be used in a variety of light-detection applications. It has a wide spectrum of sensitivity and is able to detect objects, presence, levels and motion. As such, it is a reliable and effective replacement for phototransistors in applications where light intensity must be accurately detected.
