VISHAY TCRT5000 Reflective Optical Sensor Phototransistor, 15mm Range

The VISHAY TCRT5000 Reflective Optical Sensor is a compact, self-contained module combining an infrared emitter and a phototransistor detector in a single 3.5mm leaded package. This integrated design simplifies assembly and provides a reliable solution for a wide array of proximity and line-following sensing tasks. Its built-in daylight blocking filter effectively suppresses ambient visible light, ensuring stable operation and reducing false triggers in varying lighting conditions.

The sensor operates on a 950nm infrared wavelength, projecting an invisible beam that reflects off a surface back to the phototransistor. It offers a peak operating distance of 2.5mm for optimal sensitivity and a practical sensing range of up to 15mm. With a typical output current of 1mA under test conditions, it delivers a clear and measurable signal for interfacing directly with microcontrollers, logic circuits, or other electronic control systems.

Applications

This versatile optical sensor is a cornerstone component in many electronic projects and commercial devices. Its primary uses include object detection, edge detection, and line following in robotics and automated systems. It is also ideal for use in sensing instrumentation and various industrial applications where non-contact detection of presence, position, or contrast is required.
