  • The IR Infrared QT50CM Photoelectric Switch Sensor is a type of sensor used for detecting the presence or absence of objects using infrared (IR) technology. It consists of two main components: an infrared emitter and an infrared receiver, both enclosed in separate cylindrical tubes.
  • The QT50CM sensor operates on the through-beam principle, which means that it requires two separate units, one serving as the transmitter and the other as the receiver, placed opposite to each other. The transmitter emits an infrared beam, which travels towards the receiver. When an object passes through the beam, it interrupts the infrared light, causing a change in the receiver's output signal.
  • The QT50CM sensor is designed to work with a wide range of materials, including solid objects, liquids, and even transparent materials like glass. It has a detection range that can vary depending on the specific model, typically ranging from a few centimeters to several meters. The sensor is highly reliable and can operate in various environmental conditions, making it suitable for a wide range of applications, such as industrial automation, conveyor systems, packaging, and security systems.

Principle of Work:

The IR Infrared QT50CM Photoelectric Switch Sensor works based on the principle of emitting and detecting infrared light. When the emitted light is interrupted or reflected by an object, it changes the amount of light that reaches the receiver. The receiver then detects these changes and converts them into an electrical output. This sensor consists of an IR LED as the emitter and an IR photodiode or phototransistor as the receiver. The IR photodiode or phototransistor is sensitive to the IR light emitted by the IR LED. The working principle is based on the use of light to recognize the presence or absence of an object, and the specific type of sensor can be used to detect the presence of target objects based on the application and configuration


  • Infrared technology: The sensor utilizes infrared technology to detect objects or changes in the environment.
  • Through-beam sensing: The sensor is a through-beam type, which means it consists of an infrared emitter and receiver that are mounted opposite to each other, allowing for precise object detection.
  • Non-contact sensing: The sensor can detect objects without physical contact, making it ideal for applications where contact-based sensing is not feasible or desired.
  • High detection accuracy: The sensor is designed to provide reliable and accurate object detection, with a high level of sensitivity and resolution.
  • Wide detection range: The sensor is capable of detecting objects within a specific range, which can be adjustable or predetermined by the manufacturer.
  • Industrial-grade durability: The sensor is built to withstand harsh industrial environments, with features such as rugged construction, high temperature resistance, and protection against dust, moisture, and vibration.
  • Fast response time: The sensor has a quick response time, allowing for real-time detection and response to changes in the environment.
