Inductive ring sensors and tube sensors

Inductive sensors

High-speed detection Pulse extension up to 150 ms Stackable > 20 mm

Our inductive ring sensors and tube sensors are engineered for high reliability, making them ideal for detecting small parts at high speeds of up to 20 meters per second. With an integrated pulse extension of up to 150 milliseconds, they ensure stable switching signals for consistent downstream processing.

Installation is straightforward: ring sensors can be mounted in any orientation and are universally fitted—lined up in rows, stacked, or arranged at distances greater than 20 mm. Tube sensors are designed for easy installation on the feed tube.

In space-constrained applications where accuracy is paramount, ring proximity sensors offer precise detection capabilities and a design focused on ease of use and efficiency across a wide range of industrial applications.

Short definition

An inductive ring sensor detects metal parts as they pass through the opening (pass-through), making it ideal for monitoring feed systems and small components in motion.

Good fit when: you need repeatable detection at high speed and want easy mounting/stacking in tight spaces.

Which series are available (and how do I compare them)?

Compare the series by pass-through size, physical dimensions, and switching function for your installation.

Selection tip: Match the pass-through to your part flow and choose dimensions that fit your feed track or tube.

Series	Pass-through	Dimension	Switching function
Close-enclosing ring sensor S-BES RI	10 mm, 10.1 mm, 15.1 mm, 25.1 mm, 25 mm, 45 mm	60 × 35 × 20 mm, 80 × 45 × 20 mm, 115 × 80 × 30 mm	Normally open (NO)
Tube sensor S-BES T	—	78.5 × 17 × 11.9 mm	Normally open (NO)

Selection guidance: for ring sensors, choose the pass-through that matches your part flow; for tube sensors, confirm tube mounting geometry and available space, then validate switching behavior.

Where are inductive ring sensors and tube sensors used?

These sensors are typically used in high-speed feeding and handling processes where small metallic parts must be detected reliably and consistently.

Typical applications

Small-part detection in feed systems (sorting, dosing, and transfer)
High-speed counting and presence detection up to 20 m/s
Space-limited installations where ring geometry improves accuracy
Tube-based feeding where quick mounting on the feed tube is required

Why they’re effective

Stable signals via integrated pulse extension (up to 150 ms)
Flexible mounting (rows, stacked, or spaced > 20 mm)
High reliability for fast-moving small parts
Efficient design for easy use across industries

FAQ: Balluff inductive ring sensors and tube sensors

Quick answers to help you specify the correct pass-through size and installation approach.

Pulse extension helps ensure a stable switching signal even when small parts move very fast. This improves reliable detection and downstream processing consistency.

Yes. Ring sensors can be lined up in rows or stacked, typically with a recommended spacing of more than 20 mm between units for reliable operation.

Choose a pass-through that allows the part to move freely through the opening without contact, while still ensuring accurate detection. Common pass-through sizes include 10–45 mm depending on the series.

Tube sensors are designed to be easily installed on the feed tube, making them a practical option when your application uses tube-based part feeding and you need compact, reliable detection.
