The IFM IER201 IEK3002BANKG/AM/SC/US-104 is an inductive full-metal sensor engineered for reliable non-contact detection of metallic objects in industrial machinery, machine tools, metalworking equipment and factory automation systems.
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 IER201 provides a 2 mm sensing range, with a real sensing range of 2 ± 10% mm and an operating distance of 0–1.62 mm. Its increased sensing range provides additional detection capability while maintaining a compact M8 × 1 sensor design.
The sensor uses a DC NPN normally-open output and operates from a 10–30 V DC supply. It supports a 100 mA permanent switching current and a 100 Hz switching frequency, making it suitable for repetitive detection tasks in industrial machinery and automated production systems.
The IER201 features a full-metal stainless-steel housing and sensing face with anti-spatter construction. The housing and sensing face are made from stainless steel 1.4404 / 316L, providing a robust sensing solution for demanding industrial applications and welding environments.
The sensor has an M8 × 1 threaded housing with a 60 mm overall length and is designed for flush mounting. It uses an M12 connector with gold-plated contacts and provides four yellow LEDs for switching-status indication.

The IER201 operates using an inductive sensing principle to detect metallic objects without direct physical contact.
When a suitable metallic target enters the detection zone, the sensor switches its NPN normally-open output. The switching signal can be connected to a PLC, industrial controller or compatible automation system for machine sequencing, position monitoring, object detection and process control.
Its full-metal construction provides a robust solution for applications where the sensor may be exposed to mechanical stress, metal particles, welding residue or other demanding industrial conditions.
The IER201 provides a 2 mm nominal sensing range with an increased sensing range.
Its real sensing range is specified as 2 ± 10% mm, with an operating distance of 0–1.62 mm. The correction factor depends on the target material and should be considered when designing the sensing application.
Steel: 1
Stainless steel: 0.7
Brass: 0.7
Aluminium: 0.6
Copper: 0.5
These correction factors help determine the practical sensing distance for different metallic target materials.
The IER201 uses a DC NPN normally-open output, making it suitable for compatible industrial control systems.
When a metallic target is detected within the sensing zone, the sensor changes its output state and provides a switching signal to the connected control system.
Its 100 mA permanent switching current and 100 Hz switching frequency support repeated detection in automated machinery and production equipment.
A major advantage of the IER201 is its full-metal stainless-steel construction.
The housing and sensing face are manufactured from stainless steel 1.4404 / 316L, with anti-spatter construction. This makes the sensor particularly suitable for applications involving welding and metalworking.
The robust sensing face is designed for heavy-duty industrial applications, while the anti-spatter construction helps support reliable sensor operation in welding environments.
The IER201 uses an M8 × 1 threaded housing with a 60 mm overall length.
Its threaded construction allows secure installation into compatible machine structures, while the flush-mountable design provides a clean and practical installation arrangement.
The IER201 provides a documented 50 bar / 5 MPa pressure rating at the sensing face, making it suitable for demanding industrial applications where the sensing face may be exposed to elevated pressure.
The sensor uses an M12 connector with gold-plated contacts.
Four yellow LEDs provide switching-status indication, helping technicians identify the sensor's operating condition during installation, commissioning and maintenance.
