The POSITAL line of magnetic rotary encoders has been expanded with the addition of the new MAGNETOCODE (MCD) Heavy Duty.
This multiturn absolute rotary encoder boasts a host of features that promises robustness against outdoor surroundings, making it ideal for use in construction cranes. Compared to the other existing POSITAL magnetic rotary encoders, it has an enhanced, upgraded housing and a more robust shaft.
“When the encoders are used in an outdoor environment, they are exposed to elements like rain and dust. Therefore, for construction machines and cranes it is especially important that everything which is mounted outside can withstand all that,” says Fraba’s Product Manager, Lucien Scholten.
The MCD Heavy Duty magnetic rotary encoder is resistant against high-pressure water cleaning and corrosion, thanks to the new, stainless steel housing that also fulfills the IP class of IP69K. In other words, it is immune against dust, water jets, as well as salt water.
In addition, with its higher shaft load, it is able to withstand higher mechanical loadings – a feature that will translate into a longer lifetime for the encoder itself. The whole encoder boasts superior robustness, making it a sturdy and reliable solution. With only one moving part – the shaft/magnet assembly – it is extremely resistant to shock and vibration, while the magnetic measurement technology is virtually immune to dust and moisture.
As with all POSITAL magnetic multiturn rotary encoders, the MCD Heavy Duty uses the innovative, Wiegend-effect technology to keep track of the number of rotations it has experienced, even if the rotations occur when there is no system power. This is accomplished by the encoder generating electrical energy from the rotation of its shaft. The reliability of the Wiegend effect means that the MCD Heavy Duty requires no backup batteries, leading to long-term cost-saving benefits to the customers.
The business sensibility of the POSITAL MCD Heavy Duty also lies in its versatility – thanks to the three different interfaces with which it is available: CANopen, SSI, and analog. The CANopen and SSI interfaces enable it to fit a variety of commonly used control systems, while the analog interface allows it to replace potentiometers.
