In addition, the sensor’s minimum output noise is impressively low, making it suitable for use even in motion-control applications with strict noise requirements.

Working Principle of the SFH 9202-3/4-Z

The SFH 9202-3/4-Z contains a sensitive PIN photodiode and digital signal interface in which light is reflected from a target object and converted into an electrical signal. This optical component emits infrared light from its irradiation window onto the target surface, and its emitted-light intensity is adjusted to calibrate the optical sensor’s response. The reflected light is then collected by the receiving window and converted to an electrical signal. The resulting output signal is in proportion to the amount of light being reflected back into the sensor.

Application Fields

The SFH 9202-3/4-Z optical sensor is ideal for a variety of motion-control applications. Specifically, it has been employed in speed control, position and angle measurement, location detection, and mechanical human-machine interfaces. It is also suitable for use in medical and safety equipment.

The SFH 9202-3/4-Z offers multiple advantages for these applications. This sensor’s high signal-to-noise ratio allows it to produce reliable output signals, while its easy integration into existing designs makes it a cost-effective choice. Additionally, its operating temperature range of -35°C to 85°C allows it to be used in a wide range of harsh environments.

Conclusion

The SFH 9202-3/4-Z is an excellent choice for applications requiring analog-output-type, reflective optical sensors. It produces a reliable output signal with low noise, and its integrated digital signal interface allows for easy integration into existing designs. Additionally, its wide operating temperature range and its high signal-to-noise ratio make it suitable for even the most demanding motion-control applications. With these features and benefits, the SFH 9202-3/4-Z is well-suited for use in speed control, position and angle measurement, location detection, mechanical human-machine interfaces, and medical and safety equipment.
