The PX-400 Series from Senpum is a family of background suppression type photoelectric sensors engineered for reliable detection in industrial automation applications. These sensors are designed to recognize objects within a specific distance range while ignoring background reflectivity variations, delivering stable performance even in environments with changing backgrounds and variable object surfaces. Models are categorized into Small Beam Spot, Standard Model, and Infrared (ray) types based on detection characteristics and range capabilities, allowing users to choose the right sensitivity and range for different tasks.
Each variant in the series is available with either NPN or PNP output versions, providing flexibility for different control and PLC interfacing needs. These sensors typically feature adjustable detection settings, compact housing, IP67 protection for industrial environments, and LED indicators for stable operation and output status feedback.
