This white paper, Encoder Feedback Devices: Basics for Motion Control Engineers , covers commonly asked questions when considering encoders for motion control applications. From basics such as mechanical configuration and absolute versus incremental to the differences in accuracy and resolution, this paper will shed some light on the encoder selection process.

Compatibility GuidesThu, 17 May 2012 00:28:47 PDT http://usdigital.com/support/resource-library/white-papers/student-white-paper-using-the-ma3 Abstract: Two electrical engineering students in the computer control program at Confederation College completed their third year project, a remote weather station, utilizing the MA3 miniature absolute encoder to test wind speed and direction on a wind vane. The MA3 was selected due to its small size, analog output of 0 to 5 Volts, and the availability of a ball bearing option to provide little to no resistance on the shaft. This paper discusses their project and the outcome of using the MA3 as a position sensor. Download the document here . White PapersThu, 17 May 2012 00:28:47 PDT http://usdigital.com/support/resource-library/white-papers/solar-tracking Abstract: Concentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the sunlight needs to be accurately focused. Being off by even a single degree could result in a significant drop in efficiency, and the biggest impact to the cost of delivering solar energy is efficiency. As with most systems, the accuracy is limited by the accuracy of the sensors used in that system. There are a number of different types of sensors that can be used in these systems. This paper discusses why an absolute inclinometer is the most effective sensor solution and why the US Digital T7 is superior to other inclinometers available today.

optical encoder modules. These modules are designed to detect rotary or linear position when used together with a codewheel or linear strip. The EM1 and HEDS modules consist of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. These modules use phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders. Both the EM1 and HEDS module provide digital quadrature outputs. The EM1 comes standard with a third index channel output on all resolutions. The HEDS is available with a third index channel output on some resolutions. The EM1 and HEDS transmissive optical encoder module are powered from a single +5VDC power supply. Additional power supply voltages for the EM1 will be available in the near future. The EM1 single-ended outputs are capable of sinking or sourcing 8mA each. The resolution of the modules and encoder disks or linear strips must match. Two mounting holes are provided to accept 4-40 machine screws. Both the EM1 and HEDS have identical mounting and pin-out configurations. For open collector and higher voltage applications, add the PC3 device , or for differential cable driver outputs, add the PC4 device . Encoder disks, linear strips, quadrature decoder chips, counter chips, computer interface boards, mating connectors and cables are also available. Differences US Digital is the designer and manufacturer of the EM1 transmissive optical encoder module. The design of the EM1 provides electrical and mechanical compatibility with the Agilent HEDS-9000 , HEDS-9100 , HEDS-9200 , HEDS-9040 , and HEDS-9140 series modules. The process of switching from the HEDS to the EM1 module should not require any mechanical or electrical changes. Simply use the EM1 and matching codewheel in place of the HEDS module and codewheel. The EM1 has a built-in index channel available on all resolutions, for both rotary disks and linear strips. The EM1 uses a US Digital designed codewheel with 2 tracks rather than 3 tracks for index versions. Non-index codewheels are interchangable between the EM1 and HEDS modules. The EM1 offers improved output drive capability and will source and sink 8mA at TTL levels.  Physically, the EM1 has no external wire loops which can interfere when mounting. The connector pins are 0.051" shorter than HEDS modules, while still providing .30" insertion depth. US Digital’s EM1 offers custom and special resolutions.
