Product Details

842E EtherNet/IP Absolute Encoders

Allen Bradley 842E series ultra-high resolution EtherNet/IP absolute encoders provide dual-port Ethernet and M12 connectors. The 842E series encoders are designed for high performance and reliability in harsh industrial environments. Encoders include an embedded EtherNet/IP switch to connect additional Ethernet/IP capable products in series and/or support a Device Level Ring (DLR) for Ethernet media redundancy.

Available in single-turn 18-bit resolution and multi-turn 30-bit resolution, these high-resolution absolute encoders are ideal for automotive, material handling and general factory automation applications.

Allen Bradley Absolute Encoder, 6000rpm Maximum Revolutions, 262144 Pulses Per Revolution - 842E-MIP9BA

For precise positioning of the rotating parts of your equipment, choose this absolute encoder from Rockwell Automation's Allen Bradley range. It has two communication channels – Ethernet and an M12 port that you can use to connect it to computers. Thanks to a 100Mbit/s transmission speed, you can expect quick data exchange with this encoder and device-level ring (DLR) technology ensures that there's steady data flow on the network. It consumes just 3W of power, so it's an energy-efficient motion-sensor component for your industrial equipment.

• Error limit range of ±0.03° for accurate position detection
• Aluminium housing material offers durability and corrosion resistance for long term performance
• Wide operating temperature range of -30°C to +85°C for use in demanding conditions
• IP67 (ingress protection) rating to withstand dust and immersion in up to 1m of water for 30 seconds

Standards and Certifications

• EN 61000-6-2 (European Norm)
• CE (Conformité Européenne)

What's meant by encoder resolution?

Encoder resolution refers to the number of counts or measuring segments in one revolution of its shaft. This absolute encoder has a resolution of 18bits of 262144ppr (pulses per revolution).
