Key Features
- Integrated SMT reflective design with co-located IR LED emitter and phototransistor detector enables close-range object and surface detection without through-hole mounting
- Phototransistor output allows direct interface to microcontroller GPIO pins or comparator circuits with a simple pull-up resistor and no external demodulation circuitry
- Compact surface-mount package suits miniaturized consumer electronics, wearables, and portable devices where space and height constraints prevent through-hole sensor use
Applications
The GP2S60B is used in consumer electronics and industrial equipment for reflective object detection, paper-end sensing in printers, position feedback in encoders, and media presence detection in card readers and vending machines. Its integrated IR emitter and phototransistor in a single SMT package simplifies PCB design by eliminating the need to align separate emitter and detector components. The SMT form factor supports automated assembly in high-volume production of handheld devices, office equipment, and home appliances.

Frequently Asked Questions
How does the GP2S60B's reflective sensing approach work, and at what approximate sensing distance does it operate?
The GP2S60B contains an infrared LED emitter and a phototransistor detector positioned side-by-side in a single SMT package. When an object or surface is within approximately 0.5mm to 3mm of the sensor face, it reflects infrared light from the LED back to the phototransistor, switching the transistor into conduction. This close-range reflective detection principle is ideal for paper-end sensing, tachometer discs, and proximity triggers where the target passes within a few millimeters of the sensor.
What type of output does the GP2S60B provide, and how does it interface with a microcontroller?
The GP2S60B provides a phototransistor output, which acts as an open-collector switch. A typical interface circuit connects a pull-up resistor of 10k ohms between the collector and the supply voltage (commonly 3.3V or 5V), and the microcontroller reads the logic level at the collector node. When reflected IR light is detected, the transistor saturates and pulls the output low; when no reflection is present, the output floats high through the pull-up, giving a direct 2-state digital signal to the MCU GPIO.
What makes the GP2S60B suitable for office automation equipment such as printers and scanners?
The GP2S60B's compact SMT reflective package allows it to be mounted flush on a PCB positioned close to the paper path or media transport mechanism, detecting the presence or absence of paper, labels, or toner cartridges within 0.5mm to 3mm. Its single-package integration of the 940nm IR emitter and phototransistor eliminates the alignment tolerance issues of discrete emitter-detector pairs, improving detection reliability across thousands of paper-feed cycles in high-duty-cycle printer and copier applications.
Can the GP2S60B be used in battery-powered portable devices, and what considerations apply to minimizing its power consumption?
Yes, the GP2S60B is suitable for battery-powered applications. To minimize average current draw, designers can pulse the IR LED drive current at a duty cycle of 1% to 10% (for example, 1ms on, 99ms off) and sample the phototransistor output synchronously with the LED pulse, reducing average LED current from a continuous 20mA to below 1mA while maintaining detection sensitivity for media presence or proximity applications in handheld and wearable devices.
