FD-L22A application field and working principle

Optical Sensors - Photoelectric, Industrial

The FD-L22A is a photoelectric switch specifically designed for industrial applications. It provides users with efficient and accurate detection, signaling, and protection in low voltage AC/DC circuits. The device is characterized by its compact size, small gap requirement, direct current switching, long service life, outstanding sensitivity, reverse polarity protection, and wide working temperature range.

The FD-L22A utilizes a highly sensitive photoelectric switch with a special infrared emitting diode. This diode in combination with the lens, allows the detector to recognize objects with an incredibly small object size compared to conventional photoelectric switches. The lens can project a focused beam, focusing the infrared light projections to create an extremely narrow sensing area. The sensing range can be adjusted in the field with the index wheel attached to the device.

The FD-L22A has two LEDs, one for power and one for sensing diagnostics which indicate the on/off status. The power LED shows the input voltage while the sensing LED blinks when an object is detected within the sensing range.

Applications of FD-L22A mainly focus on protective systems, photoelectric gates, industrial light curtains, automated production lines, and motion control applications. The small size, self-contained housing, and simple mounting construction also makes the FD-L22A great for a wide variety of mounting solutions.

The FD-L22A offers two features that make it a particularly attractive purchase. One is the fact that it is a low voltage AC/DC switching device. This allows the user to power the detector from a much lower voltage than is typically used in industrial applications. This makes the device easier to install in challenging locations. The second feature is the long life of the device. The use of recent advances in technology has allowed the FD-L22A to exceed 5 million switching cycles, with no deterioration in performance.

The FD-L22A is an excellent choice for applications that require reliable, accurate, and cost effective detection. Its low voltage, long service life, and small size make the FD-L22A the perfect choice for a wide variety of applications. Whether you’re looking for photoelectric gates, industrial light curtains, or automated production lines, the FD-L22A is the ideal choice.
