January 31, 2019 – Encoder Products Company, manufacturer of motion sensing devices, has added more options for its low-profile 30 mm diameter magnetic encoder modules.

The Model 30M and Model 30MT provide accurate incremental feedback, even in harsh operating conditions, by means of advanced sensing and signal processing technology. 

The Model 30M and Model 30MT combine a Hall-effect sensor, advanced signal processing circuitry, and a small magnetic target that can be affixed to a rotating shaft via a supplied shaft adaptor or insert. With a wide sensor-to-magnet air gap and excellent waveform symmetry and repeatability, the Model 30M tolerates shaft misalignment and delivers signal accuracy exceeding that of other magnetic encoders. The Model 30M is available with connector options of an eight-pin M12, eight-pin Molex, or 16-pin Molex. The Model 30MT comes with an eight-pin M12 connector and a threaded housing for easy installation.

The Model 30M and Model 30MT now offer any resolution from 1 to 1024 CPR (4096 PPR with quadrature counting). With the 16-pin Molex connector on the Model 30M, users can choose any option from one-pole to 16-pole commutation.


These encoders are capable of operating in temperatures from -40º C to 120º C and can be sealed to IP69K. With a sensor-to-magnet air gap of 0.022”, the Model 30M and Model 30MT holds ratings of 100g at 11ms for shock and 20g at 10 to 3000 Hz for vibration.

The Model 30M and Model 30MT are versatile, cost-effective solutions for non-contact, end-of-shaft rotary feedback in commercial, industrial and non-industrial applications. Some examples are servo or stepper motor control, mobile equipment speed and steering sensing, timber processing machinery, studio and stage equipment, solar panel positioning, vending machines, rotary valve positioning, punch presses, and robotics.
