The IFM UIT520 ultrasonic diffuse reflection sensor is designed for non-contact object detection and distance measurement with IO-Link communication. It provides switching and analogue sensing capabilities and can be integrated into modern automation systems for intelligent parameterisation and process monitoring. The sensor is suitable for applications involving material handling, positioning, presence detection and automated production processes.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
UIT520 uses ultrasonic diffuse reflection sensing to detect targets without physical contact. The sensor supports IO-Link communication, allowing configuration and process data exchange with compatible automation systems. IFM documentation for the corresponding UIA03500E1KG/IO-Link/US model specifies a 250–3500 mm detection range, PNP design and M30 × 1.5 housing.
The sensor provides a 250 to 3500 mm detection range for a 200 × 200 mm reference target. It provides one digital and one analogue output and can communicate through IO-Link. The analogue output operates from 4 to 20 mA, while the switching output is PNP. Its 10–30 V DC supply makes it suitable for common industrial automation systems.
UIT520 is suitable for object detection, distance measurement, material positioning and automated process monitoring. IO-Link communication makes it useful in connected automation systems requiring parameter access and diagnostic information. It can be integrated into conveyors, packaging machines and material-handling equipment. The sensor's robust industrial housing supports machine-level installation.
UIT520 combines ultrasonic detection with IO-Link connectivity for modern industrial automation. Its switching and analogue outputs provide flexibility, while IO-Link enables convenient parameterisation and communication. The sensor's M30 × 1.5 housing and 10–30 V DC supply support practical industrial integration.
