Inductive distance sensors
Inductive sensors
Non-contact measurement Absolute analog / IO-Link output Teachable linearity
Our BAW inductive distance sensors measure various positions and distances and can differentiate between material variants. They work without making contact, helping deliver a long service life free from wear.
The included teach function provides an adjustable linearity range—supporting quick commissioning during initial installation and short downtimes when replacing sensors.
Multiple configurations make inductive distance sensors easy to integrate into many applications, including monitoring movements in joining, pressing, or clamping equipment and detecting axle imbalances and expansions. Sensors supply an absolute analog voltage, analog current, or IO-Link signal.

Selection guidance: define your measurement task (distance, material variant influence, target type), then choose the interface (voltage/current/IO-Link) and verify installation constraints for stable linearity.
Where are inductive distance sensors used?
Inductive distance sensors are typically used when you need continuous feedback of distance or position to metallic targets—especially in industrial automation where contact-free measurement improves uptime.
Typical applications

- Mechanical engineering: position and distance monitoring on axes and tooling
- Detection of axle imbalances and expansions
- Commissioning setups where teachable linearity speeds changeovers
Why teams choose BAW
- Wear-free sensing thanks to non-contact operation
- Fast response with high reproducibility
- Flexible integration across many housings and connection options
- Simple outputs via analog voltage/current or IO-Link
FAQ: Balluff inductive distance sensors
Quick answers to help you specify the right measuring range and output type.
It means the sensor provides a continuous, absolute output signal that corresponds to distance (rather than only a switching ON/OFF state). Depending on the model, this is delivered as analog voltage, analog current, or IO-Link.
The teach function allows you to set or adapt the working range and linearity behavior for your setup, helping enable faster commissioning and reducing downtime during sensor replacement.
Balluff inductive distance sensors cover measurement ranges from 0.2 to 50 mm (with teachable options depending on the series). Choose the range based on the minimum and maximum distance you need to measure to the metallic target.
Analog voltage/current is ideal for straightforward PLC analog inputs and fast signal processing. IO-Link is ideal when you want parameterization, diagnostics, and standardized point-to-point communication in addition to the measured value.
