Overview - The CDD11N infrared photoelectric sensor uses diffuse reflection mode for non-contact detection. It supports both NPN and PNP outputs and operates on 10-30 VDC. It functions as an optical proximity switch and is available in multiple models, with CDD11P as the first in the family, followed by CDD11N, 40N, and 40P. Key benefits - Reliable non-contact detection across a range of surface colors and finishes. - Flexible wiring with NPN or PNP outputs for easy integration with PLCs and controllers. - Wide supply voltage (10-30 VDC) reduces the need for multiple power supplies and simplifies mounting. - Compact form factor suitable for tight spaces in automation and packaging lines. - Built to perform consistently in industrial environments with minimal maintenance. Why you need it - Improves line efficiency by providing fast, repeatable object detection without physical contact. - Reduces setup time with simple wiring and straightforward threshold behavior. - Enhances process control by offering two common transistor outputs for compatibility with different control systems. Use scenarios - Detect part presence on a conveyor belt to trigger next-stage handling or sorting. - Verify object position before sealing or packaging to prevent waste. - Sensing in automated doors or vending machines to enable smooth, reliable operation. Models and compatibility - Model lineup includes CDD11P (first), CDD11N, 40N, and 40P. This sensor is suitable for integration wherever a diffuse-reflection, non-contact proximity switch is needed.
