The BMF T-Slot magnetic sensor
For more flexibility in automation

Balluff's BMF T-slot magnetic sensors set new standards in this product category, especially due to their outstanding priceperformance ratio and their innovative ability to automatically function with both axially and radially-oriented magnets. This makes it the first choice for OEMs and end users in the material handling, pneumatic systems and packaging equipment segments.
Magnetic sensors from Balluff are indispensable in modern industry. They are used in a wide range of applications, from factory automation to robotics. With their non-contact position detection, magnetic field sensors from Balluff are reliable and wear-free, with no contact wear, no switch bounce and accurate switching points, even at high travel speeds.
Cost efficiency meets advanced detection
The BMF T-slot represents a clever simplification within our product range by focusing on the essentials without compromising on performance. This presents a leaner and more efficient offering which not only simplifies the selection process for our customers but also leads to significant cost savings. An example of this is the sensor's ability to automatically detect the orientation of solenoids both axially and radially. With the BMF T-slot, you no longer have to worry about which sensor variant you need in advance.
The transparency and high availability of the system ensure smooth operation and easy maintenance. At the same time, assembly and disassembly from above are particularly easy and allow quick and simple integration into existing systems. Combined with the optimization of the clamping screw, this makes the BMF T-Slot an unsurpassed solution that not only increases efficiency, but also enhances operational reliability.
Features
- Best price-performance ratio
- Automatic detection of axial and radial magnet alignment
- Optimization of clamping screw
- High transparency and availability of the system
- Simple assembly/disassembly from above
BMF T-Slot magnetic sensors in pneumatic cylinders
Cylinder sensors are used to detect the position of the piston in pneumatic cylinders. They are mounted directly on the cylinder.
They detect the ring magnet attached to the piston through the housing wall, which is made of non-magnetisable material (e.g. aluminium, brass or stainless steel).
BMF T-Slot magnetic sensors in grippers
Grippers (small parts grippers, universal grippers, large stroke grippers, swivelling grippers) are ideal for the safe and precise handling of workpieces.
The option of equipping the grippers with magnetic switches increases their functionality, process reliability and productivity.
