Inductive rotary encoder

There are two main types: absolute and incremental (relative). The output of absolute encoders indicates the current position of the shaft, making them angle transducers. Confusingly, they can also be referred to as rotary encoders , shaft encoders, angle encoders, angular encoders or even angle sensors, angle transmitters – the list goes on.

For the purposes of this paper we will simply use . Precise, reliable non-contact inductive rotary position sensors for Original Equipment Manufacturers, proven in harsh environment applications.

Zettlex IncOder Inductive Angle Encoders are non-contact for high-precision, reliable measurement in harsh environments over 1million product variations.

IncOder style inductive encoders have no contacting, delicate or wearing parts, so there is no need for periodic replacement, service or maintenance.

The special highlight of the expanded series is the EBI 135. Under normal operating conditions and . The inductive absolute rotary encoders . This product is not recommended for new design in - Availability on request. Your contact information for product inquiry.

Productive Injection Molding with Inductive Rotary Encoders. Machine designs for the injection molding of plastics increasingly depend on hybrid or even all- electric drive technology. High-efficiency electric drives close the mol dose, inject and dispense as well as actuate the frequently coupled extraction . In robotics and automation technology, rotary encoders and resolvers serve on servo drives as feedback systems for position and speed control.

An increasing number of applications require multiturn versions of absolute encoders that are low in cost and as sturdy as resolvers, but with features beyond . Our IncOder range of inductive angle encoders has over 100 . It is not surprising that design engineers find it difficult to select the appropriate kind of sensor for their project, as many position technologies are available. This article discusses the operation of optical and inductive encoders , and looks at their strengths and weaknesses. The encoder head measures only 9. The pulse-frequency ranges from zero up to 200kHz. Optical ring encoders are well-suited to applications where the . Though we focus on Hall-effect and magnetoresistive types, inductive encoders are the third most common rotary magnetic encoder type.

They operate by tracking reactionary current-flow resistance (to nearby material) in one or more coils. Soft iron or ferrite sensitivity to high temperatures can be . Non-contact, inductive angle encoders for high-precision, reliable measurement in harsh environments. Traditionally optical glass scale encoders were used for high accuracy direct linear measuring. Magnetic and inductive encoder alternatives today have significant advantages over glass scale technology.

Inductive and magnetic encoders are more durable, use non-contact sensing, integrate better, and offer high accuracy . Product News, TURCK is one of the leading manufacturers in factory and process automation – sensors, fieldbus and interface technology, connectivity, RFI identification etc. Motion can be determined by change in position over time. Optical technologies include shadow, self imaging and interferometric.

As an electro-mechanical device, an encoder is able to provide motion control system users with information concerning position, velocity and direction. Linear encoders are used in metrology .
