842E EtherNet/IP™ Encoders

High Resolution with DLR

Description

The 842E is an ultra-high resolution encoder with EtherNet/IP inter face. These encoders
provide 18-bit single-turn resolution and 30-bit multi-turn 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

• 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)

•Revolution divisor

• Solid and blind hollow shaft options

Configurable Parameters Typical Applications

• Counting direction • Packing machines

• Counts per resolution • Robotics

• Counts of revolution • Printing machines

• Preset value • Rotary table positioning

• Velocity unit

• IP address

Product Selection

Rigidly coupling the encoder shaft to
the machine shaft will cause a failure in
either the bearings of the encoder or
the bearings of the machine shaft.
