A hall effect encoder uses a hall-array sensor passed over a magnetic field to produce a signal that is then interpolated to resolution. Dynapar hall effect magnetic encoders use a magnetic phased array sensor to average the signal over multiple detectors to deliver a robust, high resolution signal that is insensitive to misalignment, shock and vibration.
Magnetic hall effect encoders can be extraordinarily robust. Because magnetic encoders are based on an inductive effect, they do not require bearings, which removes a point of failure from the system. Typically, the electronics inside the hall effect encoder are encapsulated so that they are not exposed to the elements. As a result, magnetic hall effect encoders can operate covered in dust in a sawmill or splashed daily in a washdown environment without any additional protection.
A magnetic hall effect encoder is designed to output reliable digital feedback in the most demanding and harshest of application environments. Applications for this technology usually require broad temperature specifications, high shock and vibration resistance, robust sealing, and contaminant protection all while focusing on output signal reliability, easy installation, and downtime reduction. Popular applications for magnetic hall effect encoders include speed and position feedback in construction, agriculture, mining, forestry and in food and beverage applications with wash downs or corrosive chemicals.
