The IFM IES231 is a precision-engineered inductive sensor developed to meet the high demands of modern industrial automation. Combining an extended sensing range with robust design and safe operation, this sensor provides engineers with a reliable and versatile solution for detecting metallic targets in space-constrained environments.

A key advantage of the IES231 is its increased sensing range of 3 mm. This extended range improves flexibility during installation and ensures accurate detection without requiring the sensor to be positioned extremely close to the target. It also supports more reliable operation across different machine tolerances, reducing the risk of misalignment and increasing system uptime.

Electrically, the IES231 is designed with a PNP output configuration and a normally open (NO) switching function. This makes it ideal for applications requiring sourcing outputs, as the sensor switches to connect the load to the positive supply when an object is detected. The NO output provides straightforward integration into a wide variety of control systems, ensuring fast and accurate responses in tasks such as position monitoring, part detection, and counting.

The sensor is housed in a threaded M8 x 1 body with a length of 50 mm, offering a compact yet durable design that can be easily mounted in confined spaces. Its threaded construction ensures quick installation and secure placement, making it suitable for machinery, conveyors, and robotic systems where space is limited but reliability is essential. The compact form factor does not compromise durability, ensuring consistent performance even in demanding industrial environments.

The IES231 is rated under Protection Class III, meaning it is designed specifically for Safety Extra-Low Voltage (SELV) operation. This enhances operator and equipment safety by reducing electrical hazards, aligning with international safety standards for low-voltage devices. Combined with its extended sensing range, this makes the IES231 a robust and secure choice for modern automation systems.

Thanks to its balance of compact size, extended sensing range, and reliable output configuration, the IES231 is suited for a wide variety of industrial applications. These include packaging machinery, robotics, material handling systems, and automated assembly lines, where precise detection of metallic objects is critical to maintaining efficiency and reducing downtime.

In summary, the IFM IES231 is a versatile inductive sensor designed to provide dependable detection in compact industrial environments. With its 3 mm extended sensing range, PNP normally open output, compact threaded housing, and SELV-compliant safety design, it delivers both performance and peace of mind. For engineers and technicians seeking a compact yet robust sensor for reliable object detection, the IES231 is an excellent choice.
