📝 Description

This Miniature Ferro-magnetic Metal detection sensor offered here provides a versatile solution for industrial applications, designed to be easily mounted using M3 screws and capable of switching moderate loads up to 10W. What sets this sensor apart is its ability to be activated solely by any Ferro-magnetic material, eliminating the need for a permanent magnet on the actuating side as depicted in the accompanying sketch. This design feature simplifies installation and operational setup, enhancing overall efficiency.

The sensor’s actuation distance can vary based on the thickness and size of the Ferro-magnetic material used, ensuring flexibility in different application scenarios. This variability allows for precise customization according to specific operational requirements, adapting seamlessly to varying environmental conditions.

To ensure reliability and consistency, every sensor undergoes thorough testing, with 100% evaluation of actuating distance before being packaged and made available for deployment. This meticulous testing process guarantees that each sensor meets stringent performance standards, delivering reliable and accurate operation in industrial environments.

The screw-mountable sensor is engineered with durability and performance in mind, making it suitable for a wide range of applications where reliable switching and ease of installation are paramount. Its robust construction and adaptable activation mechanism make it an ideal choice for environments where Ferro-magnetic material detection is crucial for operational efficiency and safety.

For further details and technical specifications, users can refer to the comprehensive product documentation available, ensuring informed decision-making and seamless integration into existing systems.
