Explore performance details, construction highlights, applications, and technical information in one clear overview.
The IFM IEP201 IEK3003-FRKG/V4A/IO/AS is a precision inductive sensor designed for reliable and repeatable position monitoring in industrial machines, automated production equipment and factory automation systems. It is intended for non-contact detection of the smallest distance changes in the micrometre range, making it suitable for applications where conventional proximity switching does not provide sufficient measurement precision.
The IEP201 combines inductive sensing with IO-Link communication, allowing the measured distance to be transmitted as a linearised process value to a compatible IO-Link master. This provides automation systems with detailed distance information for monitoring, control and process optimisation.
The sensor provides an IO-Link measuring range of 0.05–3 mm and an IO-Link switch-point range of 0.05–2.91 mm. Its resolution is 5 µm, while repeatability is specified at less than 10 µm. These characteristics make the IEP201 suitable for precise position monitoring and small-distance measurement applications.
The IEP201 uses an M8 × 1 threaded housing with an overall length of 60 mm. Its stainless-steel housing and compact construction provide a practical solution for integrating precision sensing into industrial machinery.

The IEP201 operates using an inductive sensing principle to detect changes in the distance between the sensor and a suitable metallic target without physical contact.
Its precision sensing capability allows the sensor to detect extremely small changes in target distance. Through IO-Link, this information can be transferred as a linearised process value, enabling connected automation systems to use the sensor for more advanced measurement and position-monitoring applications.
The electrical configuration can be parameterised through IO-Link. The sensor supports PNP or NPN operation and can be configured for normally-open or normally-closed switching, providing flexibility when integrating the sensor into different control architectures.
The IEP201 is designed specifically for micrometre-range distance detection.
Its IO-Link measuring range extends from 0.05 to 3 mm, while the switch-point range is 0.05 to 2.91 mm. The sensor provides 5 µm resolution and repeatability of less than 10 µm.
This precision makes the sensor suitable for monitoring small movements, machine positions, component alignment and other applications where accurate distance feedback is important.
The IEP201 incorporates an IO-Link communication interface for digital parameterisation and process-value transmission.
The sensor uses IO-Link COM2 communication at 38.4 kBaud, supports IO-Link revision 1.1 and has a minimum process cycle time of 3.2 ms.
IO-Link communication allows the sensor to provide more detailed information than a conventional switching sensor and supports convenient parameterisation within compatible industrial automation systems.
The IEP201 provides a parameterisable PNP/NPN electrical design.
The output function can also be configured as normally open or normally closed through IO-Link. This makes the sensor adaptable to compatible PLCs, IO-Link masters and industrial controllers without requiring different physical sensor versions for different switching configurations.
The IEP201 is designed to be magnetic-field immune, with a maximum specified magnetic-field immunity of 300 mT.
This feature can be useful in industrial machinery where magnetic fields may be present around motors, actuators or other equipment.
The IEP201 features a stainless-steel threaded housing with an M8 × 1 thread and 60 mm overall length.
The documented materials include stainless steel 1.4404 / 316L for the housing and mounting nuts. The sensing face is made from white LCP, while the LED window uses PPSU.
The sensor is designed for flush mounting, allowing suitable installation into compatible machine structures.
