Magnetic Encoders

Magnetic Encoders

As automation is becoming miniaturized, we see a demand to produce high-performance encoders to fit on, or in, smaller and smaller motors. Magnetic encoder technology is resistant to contamination, including dirt and moisture. This allows for an economical choice across a broad range of applications. Rotary encoders can use optical or magnetic scanning to monitor speed, position, angle and acceleration. Rotary encoders are available in different versions so that they can be optimally integrated into the respective application. This includes various mechanical and electronic connection options including a wide range of accessories. The automotive industry, mechanical and plant engineering, mobile equipment and storage and conveyor technology are just a few sectors that can benefit from the multitude of possible uses of rotary encoders.

Some magnetic encoders can offer on-site programmability at the motor manufacturer. There is no need to purchase numerous encoder configurations to satisfy a multitude of customer needs. This technology features multiple resolution programming in combination with just a few magnetic target disk configurations to achieve nearly all common resolutions. Magnetic rotary encoder ENA58IL series from Pepperl + Fuchs is a powerful encoder that works with an extremely effective magnetic detection principle, which for the first time combines the established processes of Hall and Wiegand sensors. The contactless technology impresses with its unique precision and robustness – even in difficult industrial environments. Even high mechanical loads such as vibration, dirt and extreme temperatures do not affect the powerful magnetic rotary encoders.

There are several benefits, which you can earn from magnetic encoders, such as precise measurement results. The contactless functional principle of the magnetic rotary encoder replaces susceptible mechanical gears. The lack of wear reduces maintenance and service work and ensures reliable processes. Especially, thanks to flexible mechanical and electrical interfaces, the ENA58IL series can be integrated in almost any industrial environment. In combination with the compact design, this creates a wide range of possible uses.

Furthermore, the extremely robust magnetic heavy-duty rotary encoders ensure the exact position of the crane boom, even under the effects of high shock and vibration and are ideally suited for the tight installation conditions in robots due to their particularly compact design of only 36 mm. Here they reliably record the position and speed of the robot arm and thus ensure smooth processes.

In conclusion, Magnetic encoders typically have much more lax assembly and shaft end play requirements. The ability of magnetic encoders to perform well over a wide range of assembly tolerances have eliminated the need for bearings in most magnetic encoders. This in turn has resulted in eliminating failure modes, lowering component cost and reduced overall axial length may applications.
