Contactless and reliable detection
Today’s pneumatic cylinders are compact, reliable, and cost-effective prime movers for automated equipment. Unfortunately, they are often provided with unreliable reed or Hall Effect switches that fail well before the service life of the cylinder itself is expended. Balluff’s magnetic field cylinder sensors are based on non-contact, solid-state sensor technology that is compatible with both reed and Hall Effect magnetic pole orientations, making them the ideal replacement for standard magnetic switches. Electrically rugged, they feature short circuit protection, overload protection, and reverse polarity protection.
Balluff's magnetic field sensors will work with magnetic strengths as low as 15 Gauss unlike the reed and Hall Effect sensors that require Gauss ratings two times higher or even more. This means that as the magnet weakens from time, heat, and other factors, the Balluff sensor will continue to perform reliably. How sure are we the Balluff sensor is better...they are backed by Balluff's exclusive LIFETIME warranty.
Magnetic field sensors for C-slots can be mounted flush, so they are suitable for space-critical applications. Since all of them can be installed from above, they also fit in those places where groove ends are closed and lateral installation is not possible.
Balluff also offers extremely short configurations that perfectly fit every gripper and short-stroke cylinder. The sensors detect the piston position without contact through the cylinder walls. The system is adaptable for cylinders and grippers with both strong and weak magnets.
Our BMF magnetic field sensors for round cylinders can be safely integrated into various applications with the appropriate hose clamp and mounting bracket. The well thought-out mounting bracket concept is suitable for most types of cylinder up to 80 mm piston diameter. The piston position is detected without contact through the cylinder walls.
Our BMF magnetic field sensors for C- and T-slots with adjustable multiple switchpoints enable quick integration of pneumatic and hydraulic cylinder drives into the machine control system.
Magnetic field sensors with fixed switchpoints typically must be manually positioned at the desired switchpoint and fastened in that position. In this case, it is sufficient to position the sensor at the approximate position and to attach it there. The switchpoint(s) are then set using the ""Teach"" button on the control panel.
In the simplest case, two different switchpoints on the same cylinder can be adjusted. In the IO-Link variant, it is possible to set and scan up to eight switchpoints within the sensor work area. As a result, up to eight different object sizes can be detected in, for example, one gripper, thus making the use of several conventional sensors superfluous. This means significantly more comfort for you as well as greater flexibility and cost savings.
Our BMF magnetic field sensors for T-slots can be mounted directly in the groove and distinguish themselves with their particularly strong hold. They can be mounted flush so that they are suitable for space-critical applications.
In addition, Balluff offers extremely short configurations for flexible usage options. The sensors detect the piston position without contact through the cylinder walls. The system is adaptable for cylinders and grippers with both strong and weak magnets.
Thanks to the especially bright LEDs, they reliably recognize the switching state of the sensor, even at large distances. The magnetic field sensors for T-slots are also available in metal housings, for use in very harsh environments, such as with welding spatter or flying sparks. Also available with magnetic-field-sensitive electronics for industrial environments with high welding currents.
Our BMF magnetic field sensors for trapezoidal grooves and trapezoidal guides can easily mount to the cylinder with mounting brackets and adapters. The sophisticated mounting bracket concept is suitable for most types of cylinders like these. In addition, we offer sensor variants that fit directly on a cylinder with a 60° and 90° trapezoidal groove, without a mounting bracket. The magnetic field sensors detect the piston position without contact through the cylinder walls. The system is adaptable for cylinders and grippers with both strong and weak magnets.
Two magnetic field sensors are often necessary for smaller pneumatic/hydraulic cylinders or grippers in order to detect the position of the piston in the cylinder. Our single-connector version reduces your mounting and wiring efforts for such applications. It allows two sensors to be connected via a single 4-pin connector (M8 or M12), which also requires only one slot when connecting to a distributor box. This enables you to double the number of possible sensors on one distributor box and simultaneously measure up to twice the number of positions on pneumatic grippers and cylinders in a simple manner.
This system will save you time and effort, as well as acquisition and storage costs.
Our BMF magnetic field sensors for tie rod cylinders can be reliably integrated into a myriad of applications. This is ensured by a sophisticated mounting bracket concept for tie rods and DUO rails, making it suitable for the most common cylinder types with any piston diameter. The piston position is detected without contact through the cylinder walls.
Our magnetic field sensors with flexible attachment systems are suitable for all groove shapes, such as T-, C-, round, or trapezoidal slots. It can be adapted to almost all cylinder types using special manufacturer-specific mounting brackets. As a result, a reliable tool is always available for detecting position on grippers and pneumatic cylinders. The main thing is that it is very flexible.
Moreover, the switchpoint is adjusted only once and is retained even if the sensor is replaced. This way you increase the functional reliability of your equipment by making sensor replacement safer and easier, even in hard-to-reach places. Our universally applicable sensor models save you storage space and can reduce your costs.
Tubular magnetic field sensors enable you to reliably detect positions in a non-contacting manner. They are vibration-resistant and switch through non-ferrous metal and aluminum walls without reducing the switching distance. In doing so, they allow for a significantly greater switching distance than inductive sensors of the same configuration size. Another benefit: Installing it flush in steel is simple to achieve.
