DCS POSITAL Explosion Proof Rotary Encoders 1 400

POSITAL’s explosion-proof IXARC rotary encoders have been certified to comply with ATEX/IECEx directives for Category 3 electrical products. These devices are suitable for use in Zone 2 and Zone 22 conditions (potential exposure to hazardous levels of explosive gases and flammable dust) and are ideal for oil and gas installations, chemical plants, woodworking operations, and grain handling facilities. Certification documents cover multiple encoder configurations and were issued by an organization with special competency in ATEX and IECEx testing and certification. 

POSITAL’s ATEX/IECEx-certified series of encoders feature aluminum or stainless-steel housings designed to eliminate electrical hot-spots or sparking that could ignite an explosion. These encoders are available in both incremental and absolute variants and are offered with optical or magnetic measurement systems. Optical encoders are suited for high-precision applications, delivering up to 16-bit resolution and excellent dynamic response. Magnetic variants offer similar resolution and feature compact, rugged designs that makes them highly versatile and suitable for harsh environments.

For many magnetic encoders, some operating characteristics can be modified through software updates with no need for mechanical changes. For example, for programmable incremental encoders, resolution can set anywhere between 1 and 16,384 PPR (pulses per revolution) by selecting the appropriate software parameters. For absolute encoders, both magnetic and optical variants are available in multiturn versions with battery-free rotation-counter systems. There is no need to test and replace backup batteries, drastically reducing maintenance requirements. 

Like other members of the IXARC encoder family, ATEX/IECEx certified models can be ordered with a wide range of mounting flange designs and shaft configurations. They are available with connectors (M12 etc.) or attached cables and support a variety of communications interfaces, including incremental, analog, SSI, Profibus, ProfiNet, CANopen, DeviceNet, EtherCAT, EtherNET IP, Modbus RTU, J1939, and Modbus TCP. This wide range of configuration options makes it possible to select an encoder configuration that will be easy to integrate into almost any machine or system.

Finding the right IXARC sensor for a particular application is straightforward. Go to www.posital.com to find a powerful product finder tool that enables a customer to specify the product features required for each application and then quickly zero in on the best available products.

DCS SEW MOVIC 1 400x275

 

When it comes to power transmission and motion control, SEW-EURODRIVE needs no formal introduction. Counted among the industry leaders in drive technology, SEW-EURODRIVE makes drive-based automation its business. SEW-EURODRIVE, founded in 1931, is a global company that specializes in gear motors, frequency inverters, drive systems, industrial gears, and control software. SEW-EURODRIVE products are distinguished by their modular components and customer-centric philosophy. Their modular components can be built in a multitude of configurations, durable gear housings, offer flexible mounting capabilities, and provide advanced electronics that ensure equipment continuously operates efficiently.

Drives & Control Solutions' sibling, Mechatronics Canada, had the opportunity to speak with Shane Carnegie, Electronics Product Manager at SEW-EURODRIVE Canada, to learn more about MOVI-C, a modular automation system that offers a full solution for automation tasks. MOVI-C has been continuously expanding its reach into the mechatronics space, offering an encompassing solution for machine builders and integrators. Below Shane walks us through some of MOVI-C’s unique features and real-world applications.

Can you explain what MOVI-C does?

MOVI-C is an all-in-one modular automation system. Building on the familiar SEW modular gear motors and previous generation inverters, we now have modular inverters, controllers and associated software which ties everything together. For example, you can have a gear box with an AC induction motor, a permanent magnet motor, or a servo motor based on your application requirements. Attached to that we can provide a motor controller which can be mounted in a panel or directly on or near the gear motor. The positioning or velocity control software can be pre-loaded into the motor controller at the factory and all that is required is to send the same standard process data words from your main PLC to the drive system to perform your desired motion. The software interface looks identical no matter what controller or underlying gear motor system is attached.

What are some of the major features that MOVI-C has to offer?
