The OPTEX CDD-11N DC24V cylindrical diffuse reflective photoelectric switch is a non-contact detection device specifically designed for industrial automation scenarios. It features an integrated cylindrical structure with a compact size and a special surface treatment that provides dust and oil resistance, making it suitable for industrial environments with slight dust or oil contamination. The switch operates on a diffuse reflection detection mode, where the integrated layout of the transmitter and receiver allows for rapid capture of the diffuse reflection light signals from object surfaces, with an effective detection range of 0-110mm. The response time is 1.5ms, and the sensitivity can be adjusted via a knob on the side to accommodate objects of different materials and colors. In terms of performance, the CDD-11N uses a wide DC24V voltage supply design, compatible with the power supply standards of mainstream industrial control systems. It also features built-in reverse polarity protection and overload protection circuits to prevent device damage caused by wiring errors. The optical components are designed to be anti-interference, effectively suppressing the impact of ambient light changes to ensure stable detection accuracy under workshop lighting conditions. The product can operate within a temperature range of -25℃ to 55℃, and its metal housing combined with precision sealing technology enhances both mechanical strength and vibration resistance. The CDD-11N is particularly suitable for applications such as logistics sorting, packaging machinery, and equipment safety protection. It can accurately detect the presence of objects on conveyor belts, the position of robotic arms, or the open/closed state of safety doors. Installation is simplified as it does not require the reflective plate configuration needed by opposed photoelectric switches. It can be easily deployed with a simple bracket fixation, significantly reducing the complexity of installation and maintenance. The product uses a universal cable connection and offers multiple detection mode options, facilitating parameter matching during system integration.
