Inductive ring sensors are used in feeding technology to detect metallic parts, such as screws or nuts, as they are transported through tubes. Objects are identified at speeds of up to 35 m/s regardless of their size, enabling precise counting and efficient flow control. Blockages, standstills or incorrect conveyance, such as no part or several parts at once, can be reliably detected.
The ring sensors from ifm offer reliable detection of even the smallest metallic objects, a very short response time and a choice of static or dynamic operating principle. Sensitivity, pulse stretching and output function can be adjusted, and an internal piece counter can be queried via IO-Link.
Static and dynamic applications
Ring sensors operate either statically or dynamically. Static sensors detect permanently present metal parts, for example, level monitoring. Dynamic sensors react only to passing parts and are suited to counting tasks or flow control. Both versions ensure a trouble-free production process in assembly systems.
IO-Link functions
The sensitivity can be adjusted using a potentiometer. Extended parameters such as pulse stretching, electrical design (PNP/NPN) and output function (NO/NC) can be configured via IO-Link. The sensor also offers IO-Link specific features, such as piece counting and diagnostic functions, providing greater flexibility for integration into connected production environments.
