Encoder Mounting Configuations

Illustrating the various method of correct Incremental Magnetic and Absolute Encoder Mounting Configurations.

In all cases refer to relevant installation instruction and correct fit-up tolerances. The use of anti-backlash coupling for shaft to shaft coupling is advised.

Encoders are applied to measure speed and position in a wide variety of applications and are therefore available with numerous mounting styles. The mounting style should be selected carefully to best fit the application at hand.

Conveyor Jam Protection – NK Technologies

When conveyors jam and the drive motor continues to run, expensive mechanical damage to the drive components often occurs. By installing an NK Technologies’ Current Operated Switch an overload condition, detected by higher than normal running amps, can be used to switch off power to the motor before mechanical damage results. The switch setting can be adjusted so it is not affected by normal changes in conveyor load. Current operated switches are the modern day equivalent of less reliable electromechanical jam relays that have been in use for many decades.

In situations where there may be large variations in load an NK Technologies Current Transducer can be used to monitor conveyor motor amp draw and output this data to the conveyor control systems, commonly a PLC. The PLC may be programmed to accomodate different setpoints for different mechanical loads so that jam protection is provided from light to heavy loads. In situations where the conveyor is not able to accept analog signals NK Technologies has developed a patented transducer with a frequency output suitable for the Digital Inputs of most PLC’s.
