GP1S093HCZ Application Field and Working Principle

GP1S093HCZ is a low-cost, highly reliable infrared LED-phototransistor navigator type photointerrupter, which belongs to the slot type transistor output optical sensors. The product is manufactured by the Sharp Corporation and is used in a variety of applications.

Applications

The GP1S093HCZ is mainly used to measure the presence or absence of light between distinct points in a system or electronic device. It is widely used in proximity sensing, light counting, shaft encoders, speed detection and material-level detection. Due to its small size, it is also well suited for installation in miniaturized devices such as mouse sensors, 3D trackers and serial interface control.

Working Principle

The GP1S093HCZ works by emitting and sensing light. A light emitting diode (LED) emits infrared light through a plastic slot gap. The infrared light is then detected by a phototransistor, which is mounted on the opposite face of the sensor. When light passes through the slot gap, it is detected by the phototransistor, which activates the circuit by providing a voltage touch to the sensor. When no light is present, the circuit remains off.

Feature

The GP1S093HCZ is a long wavelength type and is designed for sensing through reflective and transparent materials such as glass and plastic. It boasts a strong resistance to interference from ambient light, operating temperature range of -40 to 80°C, and long sensing range of 6mm. Additionally, its photoemission and reception axes are arranged at an angle of 90°, and an angle of sensitivity is included, making it ideal for sensing through transparent materials.

Conclusion

The GP1S093HCZ is a highly reliable, low-cost, optical sensor that is used in a variety of applications. Its angle of sensitivity and long sensing range make it well suited for material-level detection and devices with miniaturized form factors. Moreover, its strong resistance to interference from ambient light makes it a great choice for applications in harsh environments.
