Absolute Rotary Encoders

Keep track of position at all times and provide a cost-effective solution in many motion control and industrial automation applications. Acuro Series rotary encoders solve the age old problem of establishing a home position without causing costly downtime or scrap.  They always know their position whereby factors such as inactivity for long periods of time and/or moves at a slow rate have no effect on these encoders.

Motor Mount Incremental Encoders

For stepper motor or servo motor control, motor mount encoders install easily without adaptors or extra hardware for fast, simple direct to motor installation (or mounting to other free shafts). Available in commercial and industrial duty hubshaft, hollowshaft or ring-mount configurations, our motor mount incremental rotary encoders provide reliable feedback for servo and stepper motor applications, even high speed motors up to 12000 RPM. Ruggedized versions with unbreakable metal disks are available for harsh environments or heat up to 120ºC.

NorthStar Brand Encoders

NEW Harsh-Duty Optical Encoders

Northstar now offers a new series of highly accurate, incremental optical encoders blended with the rugged magneto-resistive performance you expect from Northstar. Choose from a growing line of harsh-duty optical encodersdesigned to provide reliable and intrisically safe operation in severe-duty - food, oil/gas and related heavy-duty industrial applications that will not corrode and can withstand temperature extremes from -40ºC TO +100ºC.

Compared to Northstar's traditional heavy-duty models, the harsh-duty optical line offers extreme shock and vibration resistance, special labyrinth sealing options on select models, hazardous environment ATEX certification and instrinsically-safe operation as well as extreme corrosion and washdown resistant stainless and nickel plated models designed for the special application needs of the food and beverage industry among others.

Harowe Brand Ultra-Performance Resolvers

Digital output, magnetic device resolvers are considered more rugged than rotary encoders for use in adverse operating conditions involving extreme temperature (up to 220 C), high shock, vibration or dirty environments. Shielded, spaced support bearings provide up to 10x the life of duplex bearings.  Tooth-wound models cut electrical error 50% and brushless models eliminate components that can limit life. Available in housed and frameless varieties.
