Description

The Sharp Microelectronics GP1S51VJ000F is a compact, reflective-type photointerrupter module engineered for precise non-contact detection. It integrates an infrared emitter and a phototransistor detector within a single housing, creating an optical gate. The presence of an object within the 3.0 mm sensing gap reflects the emitter’s light back to the detector, causing an output state change. This principle provides reliable, wear-free sensing for position, speed, and end-stop detection.

Housed in a durable plastic case measuring 12.2 x 10 x 18 mm, the module is built for mechanical integration. It features 3.2 mm diameter mounting holes on both sides for secure through-hole fastening. The vertical slit on the detector side, with a width of 0.5 mm, enhances its ability to detect alternating motion or fine edges. With an operating temperature range of -25°C to +85°C, it is suitable for demanding industrial automation, printer mechanisms, and consumer electronics applications.

Key Features

  • Reflective Sensing Principle: Integrated IR LED and phototransistor enable object detection without physical contact, ideal for position and motion sensing.
  • Precision Optical Design: Features a defined 3.0 mm sensing gap and a 0.5 mm vertical slit for accurate detection of fine details and alternating motion.
  • Robust Mechanical Integration: Durable plastic housing with 3.2 mm diameter screw fixing holes on both sides for secure, vibration-resistant through-hole mounting.
  • Wide Temperature Operation: Reliable performance across an industrial-grade temperature range from -25°C to +85°C.
  • Phototransistor Output: Provides a simple digital or analog signal compatible with microcontrollers, PLCs, and logic circuits.
  • Environmentally Compliant: Manufactured to meet RoHS directives, ensuring lead-free and hazardous substance-free construction.

Applications

  • Paper or media detection in printers, copiers, and ATM mechanisms.
  • Rotary encoder disk sensing for motor speed and position feedback.
  • End-stop and limit switch replacement in CNC machines and 3D printers.
  • Object presence detection in vending machines and automated dispensers.
  • Slot detection and tamper monitoring in security and access control systems.

Frequently Asked Questions

What is the output signal type of the GP1S51VJ000F photointerrupter?

The GP1S51VJ000F provides a phototransistor output. The collector-emitter current varies with the amount of reflected infrared light received, allowing it to function as a simple switch or provide an analog signal level. It can be easily interfaced with a microcontroller's digital input pin (with a pull-up resistor) or an ADC for threshold detection.

How do I mount and align this reflective photointerrupter?

Mount the module securely using the 3.2 mm diameter screw holes on both sides of its housing. For reflective sensing, the target object must pass within the 3.0 mm gap in front of the sensor face. Ensure the reflective surface of the target is aligned with the vertical slit (0.5 mm wide) to achieve reliable detection. Proper alignment is critical for consistent operation.

What is the operating voltage and how do I connect it?

The sensor requires an external infrared LED (emitter) to be driven. A typical circuit involves connecting a current-limiting resistor in series with the IR LED anode to a 5V supply, with the cathode to ground. The phototransistor collector is connected to your logic supply (e.g., 3.3V or 5V) via a pull-up resistor (e.g., 10kΩ), and the emitter is connected to ground. The output signal is taken from the collector node.
