Heavy, Mill-Duty Encoders

Dependability Under Extreme Conditions

For over 25 years, Avtron has manufactured Heavy, Mill-Duty (HMD) encoders for drive feedback in severe environments for the continuous-process industries. Our rugged designs coupled with robust, sealed electronics will provide many years of trouble free service when properly installed in their intended applications.

The World’s First HMD Encoders with Smart Electronics

Continuous-Process industries strive to maintain production and minimize unscheduled shutdowns. Outages caused by encoder failures have been a headache to many production and maintenance managers. Avtron solved this problem with the introduction of the M285, M485, and M685 SMARTachTM line of HMD encoders. These units incorporate the latest in sensor technology with Adaptive Electronics that maintain signal quality for the life of the sensor and Fault Check circuitry to warn maintenance personnel of an impending sensor failure long before a failure occurs. An open collector Alarm output is available to signal a PLC or alarm panel and let operators know so maintenance can be scheduled at the next planned outage. Time spent troubleshooting the cause of an unscheduled outage is also eliminated. Replaceable sensors are part of the package and take about one minute to swap out, thus eliminating the time it takes to swap out the entire encoder.

M285

M285

The Avtron Model M285 SMARTach is a high performance modular rotary pulse generator, designed for use as a feedback device for AC and DC drive control systems. It relies on the same field proven principles as Avtron’s well known SLAPTach (TM) pulse generator, but provides greater resolution, up to 1200 PPR. Additionally, as a result of five years field research, the M285 incorporates features that make it mechanically and electrically more reliable than any other pulse generator available today.

The newly released Avtron M285 QUADTach is a high performance modular rotary pulse generator, designed to provide speed feedback to AC and DC drive control systems.The M285 QUADTach is available with up to four (4) field replaceable sensor assemblies, which eliminates the need to gang together 2 or more encoders to obtain multiple outputs. This allows the user greater application flexibility and can reduce downtime by allowing an unused sensor to act as a spare. This unit is otherwise functionally identical to the M285 SMARTach.The M285 QUADTach line driver outputs can be had with 240, 256, 300, 480, 512, 600, 960, 1024, or 1200 pulses per revolution with various connector options such as the MS Style, Industrial Style, and Right Angle Style Connectors with mating plugs.

Sensors are available with 5vDC, 12-15vDC, or 24vDC line drivers.

The M193B is the latest version of the original Avtron SLAPTach (TM) that was introduced in 1984. The reliable modular design has made it one of our most popular models. The M193B can be used in applications that previously used older style Avtron SLAPTachs, like the M180, M182, M190, M192A, M193A and others.

The M585 SHAFTach (TM) is the original shaft mounted pulse generator developed by Avtron in 1990. Since then, it has been used in hundreds of applications where mounting problems prevented the use of conventional designs. The M585 eliminated the need for adapter flanges and couplings that are expensive and can contribute to mechanical problems, especially on larger motors.

The Avtron Model M785 pulse generator is a zero-speed rotary transducer, allowing operation down to zero RPM. The M785 generates a specific number of pulses for each rotation of its shaft. When coupled to a machine, its output is directly proportional to process travel (pulse count) or speed (pulse rate).
