New encoders for servo motors from Kuebler support a range of interfaces
Kuebler’s new Sendix 36 motor feedback system is designed to operate with servo motors of various sizes, performance levels, electrical interfaces and technical requirements, including high rotational speed and high temperature—making it ideal for semiconductor manufacturing, packaging and other factory automation systems. With its compact 36-mm housing, the S36 is equipped to handle all single-turn […]
What’s the difference between ac and dc stepper drives?
Drives for stepper motors can have inputs that are either ac or dc. What happens inside the drive is that the input signal is converted to a series of square wave pulses that are applied to the motor’s windings to power the motor and produce motion. However, stepper motors themselves function as ac motors (they […]
Joral debuts non-contact rotary encoder for harsh environments
Joral LLC introduces the PE18 ProxEncoder non-contact rotary encoder product line. Modeled in a threaded proximity switch housing, the 18-mm true non-contact encoder is designed to capture rotary motion where conventional sensors fail. Two USPTO patents enable the PE18 ProxEncoder to detect on-axis rotation with up to 0.5-in. (12 mm) air gap between the application […]

What are IEC 61131-3 and PLCopen?
The IEC (the International Electrotechnical Commission) is an international standards organization that publishes electrical and electronic standards. Hundreds of them, in fact; standardizing everything from letter symbols in electronics to medical equipment and railroad communication and signaling. Specifically, IEC 61131-3 is the standard for “Industrial-process measurement and control – programmable controllers.” It sets standards for […]

What is a rotary indexing table?
Rotary indexing is a process where repeated angular displacement during a machine cycle is followed by motionless dwell. A rotary indexing table is specifically designed to make repetitive moves around a platform. Essentially, they are highly precise work-positioning devices that index parts to be worked or machined in multiple operations. A rotary indexing table is an […]
