Frequently Asked Questions

What is the sensing principle of the GP1S296HCPSF?

The GP1S296HCPSF is a reflective photointerrupter. It contains an infrared LED emitter and a phototransistor detector facing the same direction. It detects objects by sensing the infrared light reflected back from a surface within its 1.0 mm sensing gap, causing a change in the phototransistor's output current.

How do I interface this sensor with a microcontroller like Arduino?

Interface is straightforward due to the phototransistor output. Connect the collector pin to your microcontroller's digital input pin via a pull-up resistor (e.g., 10kΩ to Vcc), and the emitter pin to ground. The signal will be logic LOW when the reflective surface is present (light detected) and HIGH when absent. Always refer to the datasheet for the exact pinout and recommended circuit.

What are the key dimensional specs for PCB layout?

The module has an ultra-compact footprint of 2.5 mm (length) by 1.8 mm (width), with a height of 1.9 mm. It is designed for standard surface-mount technology (SMT) assembly. The critical optical specifications are a 1.0 mm effective detection gap and a 0.2 mm wide slit on the detector side for precision.

What is the operating temperature and storage range?

This photointerrupter is rated for continuous operation within an industrial temperature range of -25°C to +85°C. For non-operating storage, it can withstand temperatures from -40°C up to +100°C, ensuring reliability during shipping, handling, and board assembly processes.
