842E-CM Integrated Motion on EtherNet/IP™
EtherNet/IP™ Absolute Encoder (with 1588 Precision Clock Synchronization)
Description
The 842E-CM is an ultra-high resolution encoder with EtherNet/IP
interface with time synchronization for motion control. These
encoders provide 18-bit single-turn resolution and 30-bit multiturn resolution. The EtherNet/IP encoder is targeted for high
performance and reliability in harsh industrial environments.
Encoder includes an embedded EtherNet/IP switch to connect
additional E/IP capable product in series and/or support a Device
Level Ring (DLR) for Ethernet media redundancy.
Features
• EtherNet/IP with IEEE 1588 Precision Clock Synchronization
• Embedded switch
• Hardware/software IP address setting
• Resolution up to 30 bits
• Protection class up to IP67
• Simple and fast set up
• Device Level Ring (DLR)
• Solid and blind hollow shaft options
Typical Applications
• Packing machines
• Robotics
• Printing machines
• Motion Control on EtherNet/IP
