FT-E23

The FT-E23 is a type of photoelectric detector—an optical sensor that converts light into electricity. It is widely used in a variety of industrial and general purpose applications to detect motion, direction, size, and presence of objects. This article will discuss the application field and working principle of the FT-E23.

Application Field

The FT-E23 can be used to detect changes in light such as motion, direction, size, and presence of objects. It is widely used in industrial automation, machine control, robots, process control, conveyor systems, package handling, taxiway lighting control, and other automated systems. It is also suitable for general usage, such as security and safety systems, pet door activation, 3D printing, traffic control, and remote monitoring.

The FT-E23 is available in two types—an infrared (IR) and visible light model. The IR model has a wavelength range of 850 to 900nm and can detect objects up to 2 meters away. The visible light model operates in the wavelength range of 500 to 600nm and can detect objects up to 1 meter away. The FT-E23 is also IP67 rated, meaning it is dust and water-resistant.

Working Principle

The FT-E23 works by sensing changes in the light intensity. When light passes through the detection zone, the FT-E23 produces an electrical signal. This signal is then used to trigger a detection alarm or other output device. Depending on the type and model of FT-E23, different sensing ranges and application specific adjustments can be made.

The FT-E23 uses two separate LED emitters—one for the visible light model and one for the IR model. The LED emitters produce a stream of light that passes through a light-sensitive photodiode. When an object is detected, the photodiode will detect the change in light intensity and send an electrical signal to the control circuit. The control circuit then activates the device’s output device, such as a relay or alarm.

In addition, the FT-E23 has adjustable sensitivity levels. This allows the device to be adjusted to the desired sensitivity, allowing for more accurate detection of objects. Additionally, the FT-E23 has a high tolerance for ambient lighting, meaning that it can be used in areas with bright ambient lighting without causing false detections.

The FT-E23 is a versatile Photoelectric Detector that is widely used in various industrial and general usage applications. It operates by sensing changes in light intensity, producing an electrical signal that is used to trigger an output device. It is available in both infrared and visible light models with adjustable sensitivity levels and high tolerance for ambient lighting, making it a reliable and accurate optical sensor.
