Two Newcomers in the World of Motion Control From Dunkermotoren and Baumer
Two new encoders have hit the industrial market: Dunkermotoren has released a high-precision encoder, and Baumer has developed a rugged encoder for mobile equipment.
Motor encoders are used in many industrial applications for precise angle positioning and speed feedback. Common applications include mobile machines like construction vehicles, industrial automation processes, and renewable energy systems. Encoders also find use in medical devices and in aerospace and defense applications for accurate control and monitoring of critical components.

The MR 38 Magnetic Encoder
Dunkermotoren, a brand owned by AMETEK, has released a new high-precision magnetic encoder called the MR 38. The MR 38 encoder is small and useful for tasks where positioning needs to be exact. It can track movement accurately with its 1024 pulses per revolution on outputs A and B, making it suitable for tasks that require complex motion.

High-precision Capability
The MR 38 features an Index Signal, which acts as a reference point for the motor's movement. The Index Signal helps ensure that the data transmitted by outputs A and B is accurate, providing enhanced safety and reliability. Each full motor rotation is divided into 4096 steps, allowing for precise control of positions with an accuracy within millimeters. The encoder can reliably transmit data with its 20 mA output current, and the encoder’s signals can be inverted to improve resistance to interference.
Users can choose between an encoder that operates on a 5 VDC or 24 VDC power supply. The MR 38’s compact size allows it to seamlessly integrate into the housing of Dunkermotoren's small BLDC motor series. This integration simplifies wiring by enabling a one-cable solution, reducing material requirements and saving space, especially in applications where space is at a premium.
The Non-contact EB360R Encoder
Baumer, a company specializing in sensors, has introduced a new compact multiturn encoder called the EB360R. The EB360R is specifically designed for use in mobile machines like construction vehicles, agricultural equipment, and working platforms. This encoder is built for harsh environments and can resist dirt, moisture, and high temperatures without needing maintenance. It is vibration and shock-resistant and features a housing height of just 22 mm when installed.

Suitable for Harsh Environments
The EB360R encoder uses a non-contact sensing principle with a separate magnetic rotor, ensuring durability without any moving parts inside the sensor. Unlike traditional rotary encoders, no shaft enters the sensor, and its electronics are fully protected from liquids and dust.
The EB360R has passed rigorous ingress protection tests, like IP67 and IP69K, ensuring it remains sealed even after years of use. The EB360R can withstand extreme conditions, such as temperature shocks and saltwater immersion, guaranteeing reliable outdoor operation. This allows mobile machines to use motor encoders, without the setback of dirt, water, and other contaminants.
