Optical Sensors - Phototransistors

The SFH 320 FAG-3-Z family of phototransistors are optical sensors that are used in a variety of applications. These sensors can detect light in the range of 250 to 600 nm. The SFH 320 FAG-3-Z family of phototransistors are primarily used in applications such as optical control systems, automation, safety and monitoring systems, and biometric systems.

The SFH 320 FAG-3-Z phototransistors are composed of an integrated LED and phototransistor that are within the same package. Both the LED and the phototransistor are connected to a single electrical connection. The LED is used to both passively detect and actively transmit light within the sensing range.

The phototransistor within the SFH 320 FAG-3-Z package works by converting light into electrons which are then collected by the collector of the device. When light is detected, the system will be closed and electricity will flow from the collector to the emitter. The amount of current that flows from the collector to the emitter is dependent on the light intensity, and this current will be used to power the device.

The SFH 320 FAG-3-Z is an optically isolated device and is used in applications where the light source and the electrical connection are not directly connected. This type of isolation reduces the possibility of electrical interference or crosstalk between the light source and the electrical connection.

The SFH 320 FAG-3-Z family of phototransistors can be used in a variety of applications. For example, it can be used in safety and monitoring systems to detect smoke or movement. It can also be used in medical applications to detect changes in a patient’s heart rate.

The SFH 320 FAG-3-Z family of phototransistors is a reliable and cost-effective solution for many applications. These devices offer a high degree of accuracy, response time, and sensitivity. As such, they are ideal for many sensor and automation applications.
