The ITR20001/T24 is a reflective object sensor from Everlight Electronics Co Ltd. This sensor integrates an infrared emitting diode (IRED) and a phototransistor in a surface-mount package. The sensor detects the presence of an object by measuring the infrared light reflected back to the phototransistor. It is widely used in various applications where non-contact object detection is required.

Applications:

• Object detection in printers and scanners
• Position sensors in optical encoders
• Vending machines
• Robotics
• Coin counters

Features:

• Compact surface-mount package
• High sensitivity
• Fast response time
• Low operating current
• Operating temperature range: -25°C to +85°C

Benefits:

• Accurate and reliable object detection
• Space-saving design
• Low power consumption
• Easy integration into existing systems
• Long operating life

Additional Details:

The ITR20001/T24 reflective sensor operates at a peak emission wavelength of 940nm. The typical forward current for the IRED is 50mA, and the collector-emitter voltage for the phototransistor is 30V. The sensing distance is typically within a few millimeters, depending on the reflectivity of the object. It's crucial to consider ambient light conditions, as excessive ambient light can affect the sensor's performance. The sensor is commonly used with a microcontroller to process the signal from the phototransistor.
