Stainless Steel Rotary Encoders from AMCI

Terryville, CT – AMCI’s DuraCoder® brand encoders are now available with stainless steel housings and an IP69K rating for operation in the most extreme conditions. AMCI DuraCoders have a superior shaft load rating; providing a longer life cycle than other encoders. Many industrial applications require encoders that withstand a variety of harsh environments. AMCI’s stainless steel DuraCoders reliably perform in applications where standard encoders fail.

With a standard IP67 rating, and IP69K rated versions available, end-users can take advantage of the DuraCoder’s protection against high pressure and high temperature wash downs; or liquid ingress from long-term immersion in water or contaminants. The DuraCoder product line comes standard with a 2.5” (63mm) housing and an oversized double row sealed bearing. Solid shaft and hub shaft versions are available with a variety of sizing options. Shaft loadings of up to 100 lbs. radial/50 lbs. axial provide maximum durability for applications that require superior strength. DuraCoder brand encoders are available in six different versions: SSI, Digital, Analog, Incremental, DeviceNet, and Ethernet/IP.

Applications that benefit from the stainless steel DuraCoder design include food/beverage processing, specialty vehicles, cranes, energy generation equipment, chemical/petroleum processing, wastewater treatment plants, offshore/marine environments, steel mills, and many other indoor and outdoor installations. With the ability to withstand the harshest environments, the DuraCoder remains the perfect solution for heavy-duty applications.

EtherNet/IP Absolute Multi-turn Encoder from AMCI

Terryville, CT – Advanced Micro Controls Inc. (AMCI), has released the NR25 series of heavy-duty EtherNet/IP DuraCoder® encoders. These networked rotary sensors provide an overall measuring range of 16 bits (single-turn resolution) plus 14 bits (number of revolutions), or 30 bits total. With both single-turn and multi-turn versions available, AMCI’s EtherNet/IP encoders are ready for any application. Designed in accordance with ODVA guidelines, the AMCI NR25 EtherNet/IP encoders are 100% compatible with Rockwell Automation, Allen-Bradley, and Schneider PLCs that support EtherNet/IP.

NR25 EtherNet/IP DuraCoder Encoder Features:

• Up to 30 bit (65536 steps x 16384 revolutions) Resolution
• Absolute Single-turn and Multi-turn
• Power over EtherNet (PoE)
• Resolver-based Durability
• IP67 Ingress Protection Rating
• Solid Shaft and Hub Shaft Versions
• Stainless Steel Units Available
• ODVA Compliant

AMCI’s NR25 EtherNet/IP encoder comes standard with Power over Ethernet (PoE), making it possible to install this encoder using a single Ethernet cable that transmits data and power. The connector and cabling requirements are cut in half, plus installation is simpler and less expensive. Additionally, the ability to program with implicit and explicit messaging allows the NR25 series encoders to easily integrate with PLCs and PACs supporting EtherNet/IP. Position resolution, counting direction, velocity format, and presets are all configured easily through the EtherNet/IP port. And the ability to configure parameters simultaneously makes the NR25 encoder quick and easy to set up.

LEDs on the NR25 EtherNet/IP DuraCoders help technicians troubleshoot from the factory floor by displaying diagnostic information including module status, network status, and link/activity status.

The ODVA compliant NR25 EtherNet/IP encoders are offered in a 2.5” diameter package with two M12 connectors on the back, supplying power and EtherNet/IP connectivity. Using Power over Ethernet, users can save time and money while also simplifying wiring, as only one connector is needed for power and EtherNet/IP connectivity. The NR25 encoder is resolver based, meaning that it was designed to provide absolute position feedback without glass discs or sensitive LED components, enabling it to withstand high levels of shock and vibration. The IP67 rated package is the solution for single-turn and multi-turn position applications requiring protection from dust and water ingress. Stainless steel versions are also available for food grade and marine environments.

AMCI Stepper Drives UL Listed

AMCI has expanded their selection of UL Listed stepper drives in response to increased safety and performance requirements for machine builders and OEMs. The SD17040, SD31045, and SD17060 series stepper drives are now certified by Underwriters Laboratories® (UL) as UL Listed products. The UL Listing mark on AMCI stepper drives indicates that the drives have been tested by UL to recognized safety standards. These newly approved drives are rated for operation in ambient temperatures ranging from 0°C to 50°C, and are compatible with AMCI’s complete line of motion controllers and high torque stepper motors.

AMCI’s stepper drives provide a wide range of features including network connectivity, onboard indexers, encoder feedback, compact design, and simplified set-up. All of AMCI’s UL-Listed drives are self-contained with their own power supplies, and range from 4.0 Arms – 9.8 Arms (Amps RMS) of output current. Additionally, a high voltage version is now available from AMCI to meet European standards that require 230Vac input. All of the units can be installed into tight spaces without thermal issues, and offer panel or side mounting for increased flexibility.

“Most machine builders and OEMs require UL approved control products because their equipment must meet safety and performance standards around the world. AMCI’s UL listed stepper drives achieve this level of excellence as verified by Underwriters Laboratories’ rigorous testing & certification”, explained Stan Mantchev, AMCI Engineer. Many stepper drives with UL approval are only recognized, whereas AMCI’s stepper drives are UL listed to ensure hassle free compliance in any installation.

Underwriters Laboratories® (UL) is a company that has developed standards and testing systems to ensure products are safe. A UL Listing mark on a product is always composed of four elements including the UL in a circle mark (logo), and the word LISTED in capital letters. UL Listed products represent products that are found to be free from reasonably foreseeable risk of fire, electric shock, and related hazards, and that the product was manufactured under UL’s follow-up service program.

ControlLogix Interface Communicates with EnDat Sensors

Terryville, CT – A direct interface to EnDat position encoders is now available for the 1756 ControlLogix PLC. The AMCI 7272 module is a digital, bidirectional interface for EnDat encoders, with features including latch inputs, onboard diagnostics, and read/write access. Utilizing Rockwell Automation licensed technology, the 7272 EnDat Interface PLC module is 100% compatible with the 1756 ControlLogix PLC.

The 7272 EnDat interface module directly interfaces with all Heidenhain EnDat 2.1 rotary encoders, high accuracy angle encoders, and linear scales. The module is digital, two-channel, and bidirectional; enabling it to transmit position values as well as read and update information stored in the encoder, or save new information. For high system reliability, sensor data such as application-specific parameters, compensation tables, error detection, and diagnostic capabilities are made available with this module. Several other features come standard.

EnDat position sensors are bidirectional, and thanks to the serial transmission method supported by AMCI’s 7272 module, only four signal lines are required. They are also self-commissioning, reporting all the encoder’s properties to the controller at power up. OEMs can download application specific data to the encoder’s freely definable memory area. By using the AMCI EnDat interface module, use of these valuable functions is made available through the ControlLogix PLC.

AMCI’s EnDat interface module paired with a Heidenhain EnDat encoder provides a feedback solution for all applications in motion control. Examples of applications that benefit from this pairing include machine tool, printing, and robotics.
