Inductive Ring Sensor – High-Speed Metal and Screw Detection

Inductive ring sensors are the ideal solution for detecting and counting small metal objects (screws, components, springs) passing through feed tubes with superior speed and accuracy.

Helps increase efficiency and minimize errors for part feeding systems and automatic screw feeders in assembly lines.

VECTOR VINA supplies a wide range of models from reputable brands such as RIKO, Jingjiake, Huayifeng... in various sizes and output options. Guaranteed genuine products, competitive pricing, and in-depth technical support.

Inductive Ring Sensor – An Essential Solution for Small Metal Part Control

In industrial automation, electronics assembly, and mass production, controlling small metal parts is a major challenge. A missing screw or a jammed component can halt an entire production line, causing significant losses in time and cost. The inductive ring sensor was developed to completely solve this problem.

Operating on the principle of electromagnetic induction, the sensor generates an electromagnetic field inside the ring. Any metal object passing through disturbs this field and is immediately detected, sending a signal to the central controller.

Key Features and Benefits

• High sensitivity and accuracy: Capable of detecting micro-sized metal objects, ensuring no defective products are missed and improving output quality.
• Ultra-fast response speed: Near-instantaneous signal response, suitable for the highest-speed production lines.
• Durable, non-contact operation: Because there is no physical contact with the object, the sensor is free from wear and tear and does not cause part jamming, extending equipment lifespan.
• Simple, flexible installation: Compact design, easily mounted around existing feed tubes in machinery systems.
• Diverse options: VECTOR VINA offers various ring diameters and NPN/PNP output options for compatibility with any PLC controller.

Practical Application: The “Magic Eye” for Automatic Screw Feeders

This is the most common and effective application of ring sensors. In blow-feed automatic screw feeders, the ring sensor acts as the final checkpoint before the screw reaches the fastening head.

1. Installation: The sensor is mounted around the screw feed tube.
2. Detection: When a screw is blown through the tube, the sensor immediately detects it.
3. Signal transmission: An “ON” signal is sent to the PLC.
4. Confirmation: The PLC receives the signal, confirms that the screw is ready, and allows the machine to execute the fastening cycle. If there is no signal, the PLC triggers an alarm (screw jam, out of screws), preventing the machine from operating with missing components.

Other Common Applications

• Electronics industry: Counting component leads, product inspection.
• Assembly industry: Detecting springs, rivets, and pins.
• Medical industry: Inspecting syringe needles during packaging.
• Food industry: Monitoring metal fragments in raw material pipelines.
