Technical Introduction of GDK-4 Photoelectric Sensor (English Version)
The GDK-4 photoelectric sensor is an industrial-grade detection device developed with advanced optoelectronic sensing technology, designed for object positioning, counting, displacement monitoring, and various industrial automation applications. Utilizing infrared light transmission and reception principles, this non-contact detection device achieves accurate object recognition, effectively enhancing the reliability of automated production processes.
In terms of core functionality, the GDK-4 employs a high-sensitivity receiver and stable light source system to maintain consistent detection accuracy under varying ambient light conditions. Its innovative anti-interference algorithm minimizes environmental impacts from dust, moisture, and other particulates. Operating in diffuse reflection mode, the detection range can be flexibly adjusted up to 5 meters according to application requirements, making it suitable for material handling, packaging machinery, automotive assembly lines, and similar industrial environments.
The sensor features a robust single-body enclosure constructed with industrial-grade ABS material, providing corrosion resistance and mechanical durability. Its compact design (30mm×15mm×10mm) allows installation in confined spaces, while the 360-degree adjustable mounting bracket enables flexible horizontal, vertical, or angled positioning. Integrated status indicators offer real-time operational feedback for simplified commissioning and maintenance procedures.
With broad application compatibility, the GDK-4 performs reliably in both standard industrial settings and specialized environments such as food processing or pharmaceutical production. Compatible with 24V DC power supplies, the device incorporates short-circuit protection and reverse polarity protection to ensure operational safety in demanding conditions. The dual NPN/PNP output configuration enables seamless integration with major PLC control systems, supporting both NO (normally open) and NC (normally closed) switching modes.
Technical parameters include a response time of ≤1ms, IP67 protection rating for dust/water resistance, and an operating temperature range extending from -25℃ to +55℃. The product is available in multiple lens configurations to accommodate specific detection requirements, including visible red light and laser versions for precision alignment scenarios. Optional accessories include mounting brackets, extension cables, and protective housings for specialized installations.
