The IFM IER204 IEB2002BARKG/AM/SC/3,0M/2LED is an inductive full-metal sensor engineered for dependable non-contact detection of metallic objects in industrial machinery, welding equipment, machine tools, metalworking systems and factory automation.

The sensor uses inductive proximity sensing technology, allowing metallic targets to be detected without physical contact. This makes it suitable for repeated detection of machine components, workpieces, fixtures and moving metallic parts while avoiding mechanical wear associated with conventional contact switches.

The IER204 provides a 2 mm sensing range with an operating distance of 0–1.6 mm and an increased sensing range. This provides reliable target detection while maintaining a compact M8 × 1 sensor construction.

The sensor features a PNP/NPN electrical design with a normally-open output and operates from a 10–36 V DC supply. It supports a 100 mA permanent switching current and a 150 Hz switching frequency, making it suitable for repetitive detection tasks in automated machinery.

The IER204 has a full-metal stainless-steel housing with an anti-spatter design. The housing, sensing face and lock nuts are manufactured from stainless steel 1.4404 / 316L, providing a robust solution for demanding industrial and welding environments.

The sensor uses an M8 × 1 threaded housing with a 45 mm overall length and is flush mountable. It is supplied with a 3 m PUR cable with 2 × 0.34 mm² conductors, providing a practical connection solution for industrial installations.

Design & Functionality

The IER204 operates using an inductive sensing principle to detect metallic objects without direct physical contact.

When a suitable metallic target enters the sensing zone, the sensor switches its PNP/NPN normally-open output. The resulting switching signal can be used by compatible PLCs, industrial controllers and automation systems for position detection, machine sequencing, object detection and process control.

Its full-metal construction provides robust mechanical protection, while the anti-spatter construction is particularly useful in welding-related environments.

Increased Sensing Range

The IER204 provides a 2 mm sensing range with an increased sensing range.

The documented operating distance is 0–1.6 mm. Correction factors vary according to the metallic target material and should be considered when designing the sensing application.

Steel: 1

Stainless steel: 0.6

Brass: 0.4

Aluminium: 0.3

Copper: 0.2

The documented hysteresis is 1–20% of Sr.

PNP/NPN Normally-Open Output

The IER204 uses a PNP/NPN electrical design with a normally-open output, providing flexibility for compatible industrial control systems.

The sensor supports a 100 mA permanent switching current, while its switching frequency is rated at 150 Hz. The maximum switching voltage drop is 2.5 V.

Full-Metal Anti-Spatter Construction

A key advantage of the IER204 is its full-metal stainless-steel construction.

The housing, sensing face and lock nuts are manufactured from stainless steel 1.4404 / 316L with anti-spatter construction. This makes the sensor especially suitable for welding equipment and demanding metalworking applications.

The metal sensing face is designed for heavy-duty use, while the anti-spatter construction helps support reliable operation where welding slag or spatter may be present.

Compact M8 × 1 Construction

The IER204 uses an M8 × 1 threaded housing with a 45 mm overall length.

Its compact construction allows installation in machinery where available space is limited. The sensor is flush mountable, providing a practical installation arrangement for compatible machine structures.

Optical Setting Aid

The IER204 includes an optical setting aid with a red LED, together with a green switching-status LED.

This visual indication assists technicians during sensor positioning, commissioning and maintenance by providing clear feedback about the sensor's adjustment and switching status.

Welding and Metalworking Applications

The IER204 is specified for use in welding applications.

Its full-metal stainless-steel construction and anti-spatter design make it suitable for machine tools, metalworking equipment and production environments where welding spatter and demanding mechanical conditions may be present.

Pressure Resistance

The IER204 provides a documented 50 bar pressure rating at the sensing face.

This pressure resistance supports industrial applications where the sensing face may be exposed to elevated pressure.

3 m PUR Cable

The sensor is supplied with a 3 m PUR cable with 2 × 0.34 mm² conductors.

The long integrated cable provides additional installation flexibility where the sensor is positioned away from the main control or connection point.
