Explore performance details, construction highlights, applications, and technical information in one clear overview.
The IFM I7R216 I7R3025-FNKG/DY/US-100-INF is a high-resolution dynamic inductive ring sensor designed for reliable non-contact detection of metallic components passing rapidly through a defined sensing opening.
The sensor uses a dynamic operating principle, making it suitable for applications where small metallic parts need to be detected at high speed. Its ring-shaped construction creates a defined sensing zone around the passing component, providing a repeatable detection point for automated counting, feeding, material-flow monitoring and production machinery.
The I7R216 features a compact 60 × 35 × 20 mm circular housing with an internal sensing diameter of 25.1 mm. This provides a practical passage for compatible metallic components while maintaining a controlled sensing area.
The sensor uses a DC NPN electrical design with a selectable normally-open or normally-closed output. It operates from a 10–35 V DC supply, has a permanent switching current of 200 mA, and provides short-circuit, overload and reverse-polarity protection.

The I7R216 is designed for high-speed non-contact detection of metallic components passing through the ring opening. Its dynamic operating principle and short response time make it suitable for applications where small parts move quickly through the sensing zone.
The sensor provides a 1.2 mm minimum steel-ball resolution, allowing detection of small metallic targets when the application conditions meet the specified requirements. The maximum specified part speed is 35 m/s, supporting high-speed automated feeding and production processes.
The 25.1 mm internal sensing diameter provides a defined passage for compatible metallic components. This makes the sensor suitable for automated feeders, feed tubes, material-handling equipment, production machinery and guided component-transfer systems.
The NPN output can be selected between normally open and normally closed, providing flexibility when connecting the sensor to compatible PLC inputs, industrial controllers and automation circuits. The permanent switching current is rated at 200 mA.
The adjustable 0.1–150 ms pulse-stretching function can extend short detection signals, helping connected control systems reliably register brief detection events when metallic parts move rapidly through the sensing opening. The response time is specified at less than 0.2 ms, with a maximum fall time of 0.2 ms.
The I7R216 is designed for applications where rapid and repeatable detection of metallic components is required.
