Description

The GP1S196HCPSF is a transmissive photointerrupter where an infrared LED emitter and a phototransistor detector are housed in a single, opposing U-shaped package. An object passing through the 1.1 mm gap interrupts the IR beam, causing the phototransistor output to switch states, providing a clean digital signal for position, speed, or end-stop detection.

Engineered with advanced transfer molding, the module ensures precise optical alignment and long-term stability. Its low-profile, surface-mount design is optimized for automated assembly and withstands a broad industrial temperature range, making it suitable for integration into printers, encoders, automated machinery, and consumer electronics where reliable, non-contact sensing is critical.

Key Features

  • Integrated IR emitter and phototransistor in a single, molded transmissive package.
  • Surface-mount (SMT) version for automated PCB assembly and reflow soldering.
  • Narrow 1.1 mm sensing gap enables detection of very thin objects or precise edges.
  • 0.3 mm slit on detector side enhances resolution and rejection of stray light.
  • Robust operating temperature range from -25°C to +85°C for challenging environments.
  • RoHS compliant, lead-free construction meeting global environmental standards.
  • Low-profile design (2.7 mm height) minimizes space requirements in compact devices.
  • Provides a clean, digital output signal compatible with microcontroller GPIO or logic inputs.

Applications

  • Paper jam and media detection in printers, copiers, and ATM mechanisms.
  • Rotary encoder disk interruption for motor speed and position feedback.
  • End-stop and limit switch sensing in 3D printers, CNC machines, and linear actuators.
  • Object presence detection in vending machines, automated dispensers, and sorting systems.
  • Slot detection in consumer electronics (e.g., disk drives, memory card readers).

Frequently Asked Questions

What is the difference between the GP1S196HCPSF and GP1S196HCZOF models?

The GP1S196HCPSF is the surface-mount (SMT) version designed for reflow soldering onto PCBs, while the GP1S196HCZOF is the through-hole version for manual soldering. Both share identical optical specifications, including the 1.1 mm sensing gap and 0.3 mm slit, but differ in package footprint and mounting style.

How do I interface the GP1S196HCPSF with a microcontroller like Arduino?

Connect the phototransistor collector pin (typically the output) to a microcontroller GPIO pin through a pull-up resistor (e.g., 10kΩ to Vcc). The emitter pin connects to ground. When the IR beam is uninterrupted, the transistor conducts, pulling the output low. When interrupted, it turns off, and the pull-up resistor pulls the output high, providing a clean digital signal.

What is the purpose of the narrow 0.3 mm slit on the detector side?

The 0.3 mm slit acts as an optical aperture, increasing the sensor's resolution and positional accuracy by defining a precise detection zone. It also helps reject ambient light and stray reflections, improving signal integrity and reliability in varying lighting conditions, which is critical for high-precision applications like rotary encoding.

What is the typical forward voltage and current for the IR LED emitter?

Consult the official Sharp Microelectronics datasheet for precise values. Typically, these IR emitters operate with a forward voltage around 1.2-1.4V. A series current-limiting resistor is mandatory; a common value is 100-150Ω for a 5V supply, resulting in an operating current of approximately 20-30 mA to ensure optimal output and longevity.
