ALS05A is a reflective object sensor manufactured by Texas Instruments (TI).

The ALS05A is a reflective object sensor manufactured by Texas Instruments (TI).

Specifications:

  • Type: Reflective Optical Sensor
  • Emitter Type: Infrared LED
  • Detector Type: Phototransistor
  • Operating Wavelength: 940 nm
  • Sensing Distance: Up to a few millimeters (depends on reflectivity)
  • Output Type: Digital (on/off)
  • Supply Voltage: 4.5V to 16V
  • Operating Temperature Range: -25°C to +85°C
  • Package Type: Through-hole (DIP)

Descriptions:

The ALS05A is designed for proximity and object detection applications. It integrates an infrared LED emitter and a phototransistor detector in a single package. When an object reflects the emitted IR light back to the detector, the phototransistor conducts, producing an output signal.

Features:

  • Compact, integrated design
  • High sensitivity to reflective surfaces
  • Built-in daylight blocking filter
  • Reliable performance in various lighting conditions
  • Suitable for industrial and consumer applications

This sensor is commonly used in applications such as paper detection in printers, object counting, and position sensing.

(Note: Always refer to the official TI datasheet for detailed technical specifications.)
