The IE5391 IEK3004-BPKG/V4A/K1/AS inductive sensor by IFM is designed for dependable non-contact detection of metallic objects in industrial automation, machinery, material handling and factory production applications. Its compact M8 × 1 threaded construction and non-flush mounting design make it suitable for machine installations where reliable proximity detection is required.

The IE5391 uses inductive proximity sensing technology to detect metallic targets without physical contact. This makes it suitable for repetitive detection tasks such as machine position monitoring, component presence detection, metal detection, counting and automated production processes.

The sensor provides a 4 mm nominal sensing range, with a real sensing range of 4 ± 10% mm and an operating distance of 0–3.25 mm. Its K=1 correction factor provides the same sensing range for steel, stainless steel, brass, aluminium and copper, making it useful in applications where different metallic materials need to be detected consistently.

Design & Functionality

The IE5391 features a robust stainless-steel V4A housing designed for industrial environments. Its M8 × 1 threaded construction and non-flush mounting configuration allow practical integration into suitable machinery and automation equipment.

The sensor uses a PNP normally-open switching output. When a suitable metallic target enters the sensing zone, the sensor switches its output and provides a detection signal to compatible PLCs, controllers and industrial automation systems.

The sensor is designed for industrial, mobile, cooling and lubricating applications, making it suitable for machinery exposed to demanding operating conditions.

K=1 Correction Factor

One of the main advantages of the IE5391 is its K=1 correction factor.

The sensor provides a correction factor of 1 for steel, stainless steel, brass, aluminium and copper. This means the sensing range remains consistent across these common metallic target materials, helping simplify machine design and sensor selection.

Magnetic-Field Immunity

The IE5391 is designed with magnetic-field immunity and supports a maximum magnetic-field immunity of 300 mT.

This feature helps maintain reliable proximity detection in applications where magnetic fields may otherwise interfere with conventional inductive sensors. It is particularly useful for demanding machinery and material-handling applications.

PNP Normally-Open Output

The IE5391 uses a PNP normally-open output, making it suitable for compatible industrial control architectures.

When a metallic target is detected, the output changes state and provides a switching signal to the connected PLC or automation controller.

This makes the sensor suitable for machine position feedback, component detection, automated counting, conveyor monitoring and production-line control.

High Switching Frequency

The IE5391 supports a switching frequency of up to 1000 Hz, allowing it to detect rapidly moving metallic objects and repetitive machine movements.

This high switching capability makes the sensor suitable for fast automated machinery, production lines, material-handling equipment and factory automation applications.
