The IFM IE5351 is a compact inductive proximity sensor engineered for precision-driven applications in industrial automation. With its 3 mm sensing range, rugged M8 threaded housing, and energy-efficient design, it delivers dependable detection performance in space-restricted environments while maintaining the durability and safety required in demanding production settings.

The sensor provides a 3 mm sensing range, allowing for precise short-distance detection of metallic objects. This makes it ideal for use in applications requiring fine positioning, part verification, or monitoring in compact machinery where accuracy is critical. The reliable sensing performance ensures stable outputs, even in high-speed or repetitive production environments.

Designed with a slim M8 x 1 threaded body and a short 37 mm length, the IE5351 is perfectly suited for installations in tight machine spaces. The compact form factor allows for seamless integration into assembly lines, robotics, packaging machines, and electronic production systems, where sensor size can be a limiting factor. The threaded design also allows for secure mounting with standard brackets and locknuts, providing stable installation in environments with vibration or shock.

The electrical design of the IE5351 is optimised for industrial compatibility and safety. Operating on a 10…30 V DC supply voltage, it supports broad integration with standard PLCs and controllers. The device consumes less than 10 mA in 3-wire operation, making it energy-efficient and suitable for systems where multiple sensors are deployed. Its Protection Class III rating ensures safe extra-low-voltage operation, while the inclusion of reverse polarity protection prevents wiring errors during installation, safeguarding both the device and the overall system.

With its inductive non-contact detection principle, the IE5351 provides a maintenance-free solution. The absence of moving parts eliminates wear and extends the sensor’s service life, ensuring reduced downtime and lower operating costs over the long term. This reliability is critical in continuous operation environments such as automotive production, electronics assembly, and packaging facilities.

Applications for the IE5351 are broad and diverse. In robotics, it provides precise positional feedback in compact robotic joints. In electronics assembly, it ensures accurate detection of small metallic parts. In automotive manufacturing, it verifies the presence or positioning of components on production lines. In general automation, its compact size and precision make it an excellent choice for systems where space efficiency and detection accuracy must work hand in hand.

In summary, the IFM IE5351 is a compact, precise, and energy-efficient inductive proximity sensor designed for modern automation environments. With its 3 mm sensing range, compact M8 x 1 / 37 mm housing, low current consumption, reverse polarity protection, and Protection Class III rating, it delivers safe, reliable, and long-lasting performance in precision-critical applications.
