New generation of compact and reliable position measuring systems in profile and rod designs
Compact magnetostrictive sensors for contactless position measurement

Where the highest precision is required for position measurement in confined spaces, Balluff offers a new generation of magnetostrictive sensors in rod and profile designs. Through the IO-Link interface, conditions such as temperature, humidity and service life can also be recorded. This information can be used for intelligent condition monitoring and offers you additional options for reducing unplanned downtime.
Where there is little space, the BTL mini rod shows its strengths
The extremely space-saving magnetostrictive sensor in a new mini rod design is particularly suitable for use in hydraulic cylinders for position feedback, in molding and rolling plants, or for lift and hoist technology. In addition, the BTL mini rod is used in injection molding machines and for monitoring the tilt angle of rotor blades in wind turbines. Furthermore, the non-contact and wear-free measurement technology guarantees a long service life and reduces downtimes.
The BTL mini rod is available in three variants, so you will always find the right product for your application. See for yourself to configure the ideal position measuring system for your application now:
BTL B1 - Rod BN/ZN - Analog | BTL C1 - Rod BN/ZN - Analog | BTL C1 - Rod BN/ZN - IO-Link | |
Interface | Analog (1 output) | Analog (2 outputs) | IO-Link |
Ambient temperature | -40...75 °C | -40...85 °C | -40...85 °C |
Linearity deviation | nnnn = 0050…0500: ± 200 µm | nnnn = 0050…0500: ± 60 µm | nnnn = 0050…0500: ± 50 µm |
Reliably measure the position of movable machine parts
The position measuring systems in a profile design also impress with their compact design. The space-saving housing design enables easy integration on movable machine parts for position measurement. This makes position measuring systems in profile designs ideally suited for use in the control of hydraulic presses in the field of forming technology, for example.
A wide range of variants is also available for the magnetostrictive position measuring systems in the profile design, which can also be individually configured. Find the right solution for your application now:
BTL C1 - Profile PF - Analog | BTL C1 - Profile PF - IO-Link | BTL B1 - Profile PA - Analog | BTL C1 - Profile PA - Analog | BTL C1 - Profile PA - IO-Link | |
Profile | Flat | Flat | Round | Round | Round |
