How are Hengstler Rotary Encoders Different from Others?

 
 
Ingress Protection
Special features such as rugged enclosures, shaft seal and special labyrinth sealing options on select models and models with magnetic sensing technology make Hengstler rotary encoders ideal solutions for applications such as washdown, maritime and outdoor machinery.

 
Ingress Protection
Energy Efficient
Features such as high accuracy, outperformed resolution, and optimized linearity resulting in smooth motor control, make Hengstler rotary encoders ideal for engineers designing for high energy efficiency – means at the same time allowing higher dynamic cycles with lower self-heating of the motor.
Battery-less multiturn-solutions are mandatory.
Energy Efficient

 
Customization
Customization is our strength. Several models offer dual output configurations, various housing materials such as aluminum, nickel and stainless steel and a wide variety of mounting options as standard. Don’t see what you need on the datasheet? Consult our experts for a custom solution.
Customization
Shock and Vibration
With features such as magnetic or phased array optical sensing, non-glass code discs and robust bearing designs allow Hengstler to provide encoders rated up to minimum 400 m/s² vibration and 300N axial and radial load.

 
Shock and Vibration

 
Extreme Temperature
With rotary encoders rated for -40 to 120°C and resolvers rated up to 220°C, Hengstler offers reliable feedback solutions for high temperature applications. The improved temperature critical motor feedback technology is an additonal significant feature.

Rotary Encoder Application Examples in Extreme Environments

 
Construction and Mining Machinery
Construction and Mining Machinery
See robust solutions for measuring position and angle of each rotating axis as well as speed feedback and wheel slip monitoring for precise geo-positioning and autonomous vehicle applications. Learn more
Specialty Vehicle
Specialty Vehicle
With unique applications come unique specifications. That’s why we offer a high degree of customization, encoder solutions designed to be rugged yet compact, wide temperature ranges and products designed to survive extreme shock and vibration environments.

 
Cranes and maritime Equipment
Cranes and Maritime Equipment
Cranes and maritime equipment are exposed to rough weather conditions and sea water and often sit idle for extended periods of time following a period of intense, often 24/7 operations when a vessel arrives in port. We offer solutions designed to survive these environments including DNV certified product that can survive high shock and vibration and offers corrosion resistant. Learn more
Wind Energy
Wind Energy
See solutions for wind turbines including pitch control, yaw control and generator speed feedback. We offer reliable solutions with wide temperature ranges, high resolution and operating sped range ideal for wind energy applications. Learn more

 
Paper and Steel
Paper and Steel
With high cost of downtime, paper and steel mills need to rely on precision encoder feedback to synchronize multiple motors for smooth production. To meet this need, we offer high performance magnetic incremental encoders with dual output options and high shock and vibration resistance.
Agricultural Equipment
Agricultural Equipment
Agricultural equipment will often sit without use for extended periods, often subject to extreme temperature ranges, until planting or harvesting season when operators will depend on their maximum performance. We offer solutions designed to operate in these conditions with encoders rated up to IP69K and high performance solutions for extreme temperature environments.

 
Oil and Gas
Oil and Gas
As resource exploration becomes increasing automated with a continued focus on safety, we offer rugged encoder solutions, designed to survive extreme temperatures and salt water environments, certified to major international and regional standards such as ATEX, IECEx, CSA and UL. Learn more
Geothermal and Solar Energy
Geothermal and Solar Energy
Renewable energy sources are often located in remote locations and require reliable feedback that can survive extreme environmental conditions. To meet these needs, we offer rotary encoders with stainless steel housing options, robust sealing mechanisms and wide operating temperature ranges.
