Rotary Magnetic Encoders

The ED Series of rotary magnetic encoders from Measurement Specialties (Hampton, VA) provides a platform for optical encoder and potentiometer replacement. The encoders use encapsulated (potted) electronics, eliminating contamination, even in severe conditions. The ED-18, ED-19, ED-20, and ED-21 encoders are offered in several packages, and feature resolutions from 64 to 1,024 counts per rotation, and integrated line driver options with active termination for longer cable runs. Analog versions are available with outputs from 0 to 5V DC, 0.5 to 4.5V DC, 0 to 20 mA, or 4-20 mA, which can be used as industrial potentiometer replacements or as human-machine interface devices.

Motion Control Integrated Circuits

Performance Motion Devices (Lincoln, MA) offers the Magellan™ family of motion control integrated circuits (ICs) with 7-segment s-curve profile generation. Available in 1-, 2-, 3-, and 4-axis versions, the programmable chips provide the control required to eliminate oscillation and reduce vibration for smoother motion and higher throughput. The 7-segment s-curve profiles reduce the change in acceleration, resulting in less wear and tear on the system and faster transfer times.

Creating Geospatial Content with Photogrammetry Software

Over the last decade, the unprecedented population growth rates throughout much of the world and the subsequent need for information to support and manage that growth has put more pressure than ever before on geographical information system (GIS) and production mapping professionals. Businesses and planners need more up-to-date information than ever before, so much so that photogrammetry production “factories” can work 24/7 and still find it a challenge to keep up with the increasing volume of work.
