CANTON, Ohio -- Timken is introducing a new M15 Modular Magnetic Encoder that it says provides more reliable feedback than optical encoders to keep motors and factory-automated equipment running longer, even in harsh environments.

Encoders are used to provide data on the speed and positioning of rotating motor shafts and equipment. Applications for encoders are found throughout many industries and the M15 encoder is specifically designed to perform in dirty environments where conventional optical encoders frequently fail due to debris interference.

Unlike optical encoders, which require precise alignment to operate, the M15 is easier to install because it uses magnetic technology that reduces complexity and also accommodates motor shaft tolerances, according to Timken. This technology eliminates interference from machine vibrations, delivering a longer operating life and more reliable performance, the company said.

Potential applications include stepper-motor positioning and anti-stall feedback, DC brush-type motor positioning, and brushless DC and servo motor control.

As well as being functional in more environments, the M15 is also designed to accommodate a wide range of motor shaft end play. The M15 encoder is also available in a wider variety of resolutions that range from 100 lines up to 2048 lines with 4/6/8/12 pole commutation and reference pulse options.

The compact Timken encoder, with a low profile of 0.68 inches (17 millimeters), is approximately 1.6 inches (41 millimeters) in diameter and uses industry standard mounting patterns of 1.28 or 1.81 inches (32.5 or 46 millimeters). The M15 fits numerous shaft sizes making it a convenient drop-in replacement for more complex optical designs.
