Are you searching online for rotary encoder manufacturers or suppliers but don’t know where to start?
Congratulations on finding this article.
As a professional rotary encoder supplier in China, Lorentzzi® can help you choose the right one.
In this article, we’ve compiled a list of the top 10 rotary encoder manufacturers and suppliers worldwide to help you save time and effort in supplier sourcing.
Now, let’s get started!
1. Lorentzzi Industrial Supply
Rotary encoders are commonly used sensors for detecting the speed and forward/reverse rotation of rotating objects, such as motors, elevators, and bearings.
Lorentzzi® is a leading manufacturer and supplier of optical rotary encoders in China. Their encoders are highly competitive and their product quality is excellent.
They specialize in providing a wide range of incremental rotary encoders for various applications, including popular hollow-shaft and solid-shaft encoders.
The maximum resolution of their encoders is not limited to 6,000 PPR, but can reach up to 10,000 PPR.
The higher the resolution, the more accurate the speed measurement.
And their encoder outputs are available in PNP, NPN open collector, voltage output, totem pole, push-pull, line driver and so on.
So, if you want to measure speed with greater precision, Lorentzzi-branded optical rotary encoders are an ideal choice.
2. Heidenhain
Throughout my sales career, I’ve been asked many times by customers to replace expensive Heidenhain incremental rotary encoders with our Lorentzzi rotary encoders.
Heidenhain is a well-known German encoder manufacturer, fully known as Dr. Johannes Heidenhain GmbH.
Its products include linear encoders, angle encoders, and rotary encoders.
Common incremental rotary encoders include the ERN 1000, ERN 1023, and ERN 400 series hollow-shaft encoders, and the ROD 1000, ROD 400, and ROD 600 series solid-shaft encoders.
These encoders are widely used in machine tools, automation, electronics, robotics, medical technology, drive systems, elevator technology, wind turbines, printing, and other fields.
3. Kübler
Now, let me introduce another well-known encoder manufacturer from Germany: Kübler, a brand that has been mentioned many times in my sales process.
Kübler is another well-regarded German encoder manufacturer with a 65-year history, founded in 1960.
The company’s incremental rotary encoders are categorized by outer diameter, ranging from a minimum of 24 mm to a maximum of 100 mm. And both hollow and solid shaft types are available.
They also produce absolute encoders and related instrumentation.
Lorentzzi offers an alternative to Kübler incremental rotary encoders.
4. Hengstler
If you’re an engineer or have worked with rotary encoders, Hengstler is a German manufacturer you can’t ignore.
Hengstler originally specialized in the production of watch springs, but its business has expanded to include rotary encoders and other industrial control products.
While best known for its incremental and absolute optical rotary encoders, Hengstler also offers other products such as safety relays, counters, and industrial printers and cutters.
Hengstler encoders are widely used in AGVs (automated guided vehicles) for precise motion control, positioning navigation, and safety monitoring.
5. Koyo
Above, we listed one Chinese encoder supplier and three well-known German rotary encoder manufacturers.
Now, we’ll introduce you to two other encoder suppliers from Japan: Koyo and Yokogawa.
Koyo is a Japanese brand whose encoder business stems from the precision bearing expertise accumulated by its parent company, JTEKT.
Koyo’s popular incremental rotary encoder series include the solid shaft type φ38 incremental TRD-SR series, the solid shaft slim and compact TRD-N series, and the hollow shaft φ38 incremental TRD-SHR series.
6. Tamagawa
Tamagawa is another well-known Japanese encoder manufacturer that offers not only incremental rotary encoders but also high-quality absolute rotary encoders.
Their incremental rotary encoders are available in either ABZ three-phase or AA-BB-ZZ six-phase configurations. They also offer hollow-shaft incremental rotary encoders with UVW signals.
UVW encoders are widely used in brushless DC motors to detect magnetic poles, enabling more precise motor control.
If you’re looking for a hollow-shaft encoder with UVW signals, Tamagawa encoders are a good choice. However, their encoders are not as competitively priced as Lorentzzi brand UVW encoders.
7. Dynapar
If you frequently search for “encoders” on Google using various keywords, you’ll often find Dynapar encoders.
Dynapar is also a well-known encoder manufacturer headquartered in the United States.
Based on encoder function, Dynapar’s products can be categorized as incremental encoders, absolute encoders, and resolvers. Based on their operating principle, Dynapar’s encoders can be further categorized as optical encoders and magnetic encoders. Furthermore, Dynapar’s encoders can be further categorized as hollow shaft encoders, solid shaft encoders, and more.
If you’re looking for different types of encoders, Dynapar will always have something to offer.
8. Baumer
Now let’s take a look at Baumer.
Baumer, the abbreviation for the Swiss company Baumer, is a world-leading company in sensors and measurement technology for industrial automation.
Baumer encoders are available in diameters from 24 mm to 85 mm, and their encoder outputs can be HTL, TTL, and sine/cosine signals.
If you’re looking for a hollow-shaft incremental rotary encoder with a larger diameter than Baumer can offer, such as an outer diameter of 100 mm or 120 mm, Lorentzzi can provide high-quality, large-diameter encoders. Contact us today for a solution!
9. Eltra
Eltra Encoder (Italy) is a world-renowned manufacturer of industrial rotary encoders and linear sensors. Founded in 1985 and headquartered in Italy, it specializes in high-precision position and velocity feedback solutions.
Their products hold CE, ISO9001:2000, UL/CSA, and ATEX certifications, making Eltra a well-established encoder manufacturer.
10. Autonics
Now let’s look at a Korean encoder manufacturer called Autonics.
In addition to encoders, they also produce a variety of other industrial control products, such as proximity sensors, safety light curtains, and switching power supplies.
Autonics enjoys a strong reputation in the Middle East, including Iran, and is also well-known in Southeast Asia.
I once met and chatted with an Iranian customer, who told me that Autonics had previously planned to build a factory in Iran but withdrew due to policy reasons.
This meeting fully demonstrated Autonics’ strength in the Middle East.
Conclusion
The 10 suppliers or manufacturers listed above all offer high-quality encoders.
If you’re considering purchasing a high-quality, reasonably priced product, Lorentzzi® encoders are a great choice.
