Introduction

The IFM I7R212 I7R3020-FNKG/DY/US-100-INF is a dynamic inductive ring sensor designed for fast and reliable non-contact detection of metallic components passing through a defined sensing opening.

Its ring-shaped construction creates a controlled sensing zone around the passing component. The dynamic operating principle makes the I7R212 particularly suitable for applications where metallic parts move quickly through the sensing area and reliable detection is required.

The I7R212 features a compact 60 × 35 × 20 mm circular housing with an internal sensing diameter of 20.1 mm. This provides a defined passage for compatible metallic parts while maintaining a controlled detection area.

The sensor uses a DC NPN electrical design with a programmable normally-open or normally-closed output. It operates from a 10–35 V DC supply and supports a permanent switching current of 200 mA.

Application Performance

The I7R212 is designed for high-speed non-contact detection of metallic components passing through the ring opening. Its dynamic operating principle allows the sensor to respond quickly when metallic parts enter the sensing area.

The sensor provides 1 mm steel-ball resolution, making it suitable for detecting relatively small metallic targets when the installation and target conditions meet the specified requirements. The maximum specified part speed is 35 m/s, supporting fast-moving components in automated processes.

The 20.1 mm internal sensing diameter provides a defined passage for metallic components. This makes the sensor suitable for automated feeders, production machinery, material-handling equipment and guided part-transfer systems.

The NPN output is programmable between normally open and normally closed, providing flexibility when integrating the sensor with compatible PLCs, controllers and automation circuits. The switching output supports a permanent current rating of 200 mA.

The adjustable 0.1–150 ms pulse-stretching function can extend short output signals. This can help connected control systems reliably register brief detection events when metallic components move rapidly through the sensing opening.

High-Speed Ring Detection

The I7R212 provides a response time below 0.2 ms and a maximum fall time of 0.2 ms, supporting fast detection of metallic components.

Machine control

The combination of dynamic sensing, 1 mm resolution, rapid response and adjustable pulse stretching makes the I7R212 suitable for automated applications where short detection events need to be reliably captured.

Ring Sensor Design

The I7R212 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 detects their presence. This provides a repeatable sensing point for automated feeding, counting and material-flow applications.

The housing is manufactured from polyamide (PA) and the sensing ring is made from POM. Electrical connection is provided through an M12 connector, allowing integration with compatible industrial sensor cabling.
