Description

The GP1S094HCZ0F operates on a transmissive photointerrupter principle, where an internal infrared LED emitter is optically aligned with a phototransistor detector across a precise air gap. An opaque object passing through this gap interrupts the light beam, causing a corresponding change in the phototransistor’s output current. This provides a clean, non-contact digital signal for position, speed, or end-stop detection.

Built with advanced transfer molding technology, the module offers excellent mechanical stability and environmental resistance. The inclusion of alignment pins prevents rotational misalignment during soldering, ensuring consistent performance. Its RoHS-compliant construction and wide temperature tolerance make it suitable for automated assembly lines and durable end-products.

Frequently Asked Questions

What is the sensing gap and slit width of the GP1S094HCZ0F?

The sensor has a precise 1.5 mm air gap between the internal IR LED and phototransistor. The detector side features a narrow 0.3 mm slit, which defines the sensing resolution and is ideal for detecting thin objects, edges, or slots in encoder wheels.

How do I interface the phototransistor output with a microcontroller like Arduino?

The phototransistor output acts as a current sink. Connect the collector pin (typically through a pull-up resistor to 5V or 3.3V) to a digital input pin on your microcontroller. When the beam is interrupted, the transistor turns off, causing the input pin to read HIGH. A simple voltage divider or comparator can be used for cleaner signal conditioning.

What is the purpose of the positioning pins on the sensor package?

The integrated positioning pins are crucial for assembly accuracy. They fit into corresponding holes on the PCB to prevent the sensor from rotating during soldering. This ensures the 1.5 mm gap remains perfectly perpendicular to the board and the object path, guaranteeing reliable and repeatable beam interruption.

What is the operating voltage and current for the internal IR LED?

While the exact forward voltage (Vf) and current (If) for the internal LED are specified in the Sharp Microelectronics datasheet, typical values for such photointerrupters are a Vf of ~1.2V to 1.4V and a recommended If of 20mA to 50mA. Always use a current-limiting resistor in series with the LED anode, calculated based on your supply voltage (e.g., 5V).
