Description

Introduction

The IFM I7R203 I7R3010-FPKG/DY/US-100-IPF is a high-resolution inductive ring sensor designed for reliable non-contact detection of small metallic objects passing through a defined sensing opening.

Its ring-shaped construction provides a controlled detection zone for metallic parts moving through the sensor. The I7R203 uses a dynamic operating principle, making it suitable for applications requiring fast and reliable detection while maintaining good resistance to contamination. IFM highlights the sensor for its high resolution, short response times, resistance to dirt and high protection rating.

The sensor has a 60 × 35 × 20 mm circular housing with an internal opening of 10.1 mm. This compact ring arrangement is suitable for monitoring small metallic components, fast-moving parts and material flow in automated machinery.

The I7R203 uses a PNP electrical design with a selectable normally-open or normally-closed output. It operates from a 10–35 V DC supply and provides a permanent switching current of 200 mA.

Application Performance

The I7R203 is designed for high-resolution detection of small metallic objects passing through its ring-shaped sensing opening. Its 0.6 mm steel-ball resolution allows the sensor to detect very small metallic targets when the application conditions meet the specified sensing requirements.

The dynamic operating principle and response time of less than 0.2 ms make the sensor suitable for fast-moving parts and applications where detection events occur over very short periods. The maximum specified part speed is 35 m/s.

The adjustable pulse stretching function from 0.1 to 150 ms can extend the output signal, helping compatible control systems register short detection events from rapidly moving metallic parts.

The PNP output can be configured as normally open or normally closed, providing flexibility when integrating the ring sensor with compatible PLCs, controllers and machine-control systems. The sensor supports a permanent switching current of 200 mA.

Ring Sensor Design

The I7R203 features a 60 × 35 × 20 mm circular housing with a 10.1 mm internal diameter. Metallic parts can pass through the central opening while the sensor monitors their presence.

This arrangement is particularly useful for automated feeding systems, small-part handling equipment, production machinery and counting applications where objects follow a defined path through the sensing ring.

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

High-Speed Small-Part Detection

The I7R203 is suitable for applications where small metallic parts move rapidly through the detection area.
