Sharp Microelectronics GP1A51HRJ00F Photointerrupter - Transmissive Type, OPIC Output
The Sharp Microelectronics GP1A51HRJ00F is a transmissive photointerrupter module with OPIC (Optical IC) output, designed for non-contact object detection and position sensing in electronic systems. It features a 3mm sensing gap and a 0.5mm vertical slit for precise motion detection, with a logic LOW output when the optical path is blocked, making it compatible with microcontroller inputs on platforms like Arduino, Raspberry Pi, and industrial PLCs.
Features
- Transmissive optical sensor with integrated OPIC (Optical IC) output for stable, noise-immune signal conditioning.
- Features a precise 3mm air gap and a 0.5mm vertical detection slit for accurate object or flag positioning.
- Outputs a digital LOW signal when the infrared beam between the internal emitter and detector is interrupted.
- Includes 3.2mm diameter screw fixing holes on both sides of the housing for secure mechanical mounting.
- Compact PCB-mount package (12.2 x 10 x 18 mm) with a wide operating temperature range of -30°C to +75°C.

The Sharp Microelectronics GP1A51HRJ00F photointerrupter employs a transmissive through-beam sensing principle, where an infrared LED emitter and a phototransistor detector are precisely aligned within a single housing, separated by a 3mm gap. The integrated OPIC (Optical IC) provides a conditioned digital output, ensuring reliable performance with high immunity to ambient light and electrical noise. This design is ideal for detecting the presence, absence, or position of an opaque object passing through the slot.
Engineered for durability, the module operates across an industrial temperature range from -30°C to +75°C and is housed in a black thermoplastic case with integrated mounting holes. Its vertical slit configuration allows it to detect alternating motion, such as in rotary encoders, paper feed sensors, or limit switches, providing a robust solution for automation, consumer electronics, and safety interlock systems.
