With the MR 38 magnetic encoder, Dunkermotoren, a brand of AMETEK, is launching a particularly compact solution for precise positioning tasks. With a resolution of 1024 ppr on channels A and B, the encoder is designed to cover complex motion profiles in a wide range of applications.

A third, so-called index signal, can be understood as a reference pulse for the movement. This can be used to determine the absolute position of the connected motor within one revolution and ensure the plausibility of the signals transmitted through channels A and B. This offers the user additional security with regard to the accuracy of the transmitted data.

A single motor revolution can be resolved in 4096 steps, allowing positions to be determined precisely and approached with millimeter accuracy. Combined with an output current of 20 mA, precise transmission is guaranteed even over long cable distances. In addition, all three signals are also available in inverted form. These differential signals increase the interference immunity of the output signal. The supply voltage of the encoder is 5 VDC (24 VDC possible on request).

Thanks to its particularly compact design, the MR 38 encoder can be fully integrated into the housing of even the small BLDC motor series from Dunkermotoren. This means that the signals can be connected directly to the motor connector, enabling a one-cable solution. This integration not only reduces the amount of material required for the complete solution, but also saves valuable space in applications where installation space is at a premium.

The result for the user is a particularly slim yet powerful drive that is guaranteed to meet the precise positioning requirements of your application.
