Bulletin 842A Multi-Turn Magnetic Encoder is a 25-bit absolute multi-turn shaft encoder. It provides up to 8192 pulses per turn or a maximum of 8192 turns. It uses a technology called Synchronous Serial Interface (SSI) to provide 24-bit resolution over just 5 wires. The SSI output from the 842A encoder can be interfaced in several different ways.

Bulletin 842D DeviceNet™ Multi-Turn Magnetic Encoder is a 26-bit absolute multi-turn shaft encoder that is directly connected to DeviceNet. This network capability eliminates the need for dedicated input cards. It connects to the DeviceNet trunk line using a five-pin micro quick-disconnect. You can interface up to sixty-three 842D DeviceNet encoders to a PLC or other logic system through a single network connection.

Bulletin 842E EtherNet/IP™ Absolute Encoders provide dual-port Ethernet and M12 connectors, providing customers with easy, cost-saving installations. Each encoder also includes an metaded Ethernet/IP switch to connect additional EtherNet/IP-capable products in series or to support a Device Level Ring for Ethernet media redundancy. These encoders are designed for high performance and reliability in harsh industrial environments.

Bulletin 842E-CM Integrated Motion on EtherNet/IP™ Absolute Encoders are designed for motion control applications that require feedback-only axes. These encoders support the standard motion instruction set in the Studio 5000™ Logix Designer application. By providing auxiliary feedback directly through an EtherNet/IP network, these encoders eliminate the need for point-to-point wiring. You can use them in a variety of network topologies such as linear, ring, or star. These encoders leverage CIP Sync, a time synchronization extension that is fully compliant with IEEE 1588.

Bulletin 842HR Sine/Cosine is a 15-bit serial encoder for high performance digital servo drive systems that require absolute feedback for position control, and high resolution incremental feedback for speed control. This encoder provides commutation, speed regulation, and position control all in one device.

Bulletin 845D Single Turn is a heavy-duty NEMA Type 4 single-turn absolute position encoder that digitizes shaft angle position into one of a number of absolute code formats. Our encoder has a unique digital output for each shaft position. It uses a single laser diode and a fiber optic assembly to produce a concentrated beam of light that passes through a code disk and is sensed as high level optical signals.

Bulletin 845G Single-Turn is a NEMA Type 4 and 13, single-turn absolute encoder for use in harsh conditions. We enhanced this encoder to incorporate the higher performance of our 845GM encoder in a standard size 25 package.

845G Single-Turn High-Performance

Bulletin 845GM Single-Turn is a NEMA Type 4 and 13, single-turn absolute encoder that digitizes shaft position for reliable readouts. You can use this encoder under a wide range of harsh conditions. The 845GM provides high resolution in a compact size 20 housing for applications where positioning accuracy is critical but space is limited.
