With 2.5 mm steel-ball resolution, NPN selectable normally-open/normally-closed output, 10–35 V DC operation, adjustable pulse stretching, fast response and IP67 protection, it is suitable for part detection, automated counting, feeding systems, congestion monitoring and industrial automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The IFM I7R210 I7R3020-FNKG/US-100-INF is a static inductive ring sensor designed for reliable non-contact detection of metallic components passing through a defined sensing opening.
Its ring-shaped construction creates a controlled detection zone around the passing component, making it suitable for part detection, automated counting, feeding systems, material-flow monitoring and congestion monitoring in industrial machinery.
The I7R210 features a compact 60 × 35 × 20 mm ring housing with a 20.1 mm internal sensing diameter. This provides a defined passage for compatible metallic parts while allowing the sensor to monitor their presence as they move through the ring.
The sensor uses an 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 reverse-polarity, short-circuit and overload protection.

The I7R210 is designed for reliable non-contact detection of metallic components passing through the ring opening. Its static operating principle makes it suitable for applications where parts move through a defined path and need to be detected consistently.
The 20.1 mm internal sensing diameter provides a practical passage for compatible metallic components. This makes the sensor suitable for automated feeders, feed tubes, material-handling systems and production machinery.
The sensor provides a 2.5 mm minimum steel-ball resolution, allowing suitable small metallic targets to be detected when application conditions meet the specified requirements. The maximum specified part speed is 35 m/s, supporting fast-moving components in automated processes.
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 switching output supports a permanent current rating of 200 mA.
The adjustable 10–150 ms pulse-stretching function can extend short detection signals, helping connected control systems reliably register brief detection events when metallic components pass through the sensing opening. The response time is specified at less than 0.5 ms, with a maximum fall time of 10 ms.
The I7R210 uses a compact ring-style construction measuring 60 × 35 × 20 mm with a 20.1 mm internal sensing diameter.
Metallic components pass through the central opening while the sensor monitors their presence. This provides a repeatable sensing point for automated feeding, counting, material-flow monitoring and congestion-control applications.
The housing is manufactured from polyamide (PA) and the sensing ring is made from POM. Electrical connection is provided through an M12 A-coded connector, allowing integration with compatible industrial sensor cabling.
The I7R210 is suitable for applications requiring reliable detection of metallic components moving through a controlled path.
