Inductive sensors
Our inductive position systems are the ideal solution for tight installation conditions. Perfectly integrable and with maximum precision, they enable inductive position measurement of metallic objects and act as a contactless depth gauge.
The inductive position sensor reliably detects linear measuring paths via a simple target. A basic machine component, like a rotary disk, can serve as the target. Depending on the version, measured values are transmitted via IO-Link or as an analog output signal.
The primary field of application for the inductive position sensors is monitoring drive spindles and clamping devices, where they guarantee an error-free clamping process. They are also used in mechanical engineering for many applications— including monitoring linear movements and detecting punching depths, positions of grippers, rollers, valves, and more. Their high reproducibility supports optimum process quality.
Balluff inductive position sensors combine adjustable measuring ranges with wear-free sensing and flexible interfaces for precise positioning tasks.
An inductive position sensor delivers a continuous position value based on the distance to a metallic target—useful for precise positioning and process monitoring, not just switching.
Use this overview to compare measuring range and interface for common Balluff inductive position sensor series.
| Series | Range / measuring range | Interface |
|---|---|---|
| Signal transmission via analog output signals 1…10 V (easy handling)
S-BPF A
|
40 mm | Analog, voltage |
| Signal transmission via analog output signals 4…20 mA (high EMC immunity)
S-BPF C
|
40 mm | Analog, current |
| Signal transmission using analog output signals 1…10 V / 4…20 mA
S-BPF E
|
133 mm | Analog, voltage, analog current |
| Signal transmission via IO-Link
S-BPF L

Selection guidance: pick the required measuring range (40 mm or 133 mm), then select the interface that best matches your PLC/IO system (analog voltage/current or IO-Link).
Inductive position sensors are typically used when you need precise, repeatable position feedback to metallic targets in machine building and automation.
