CUI Adds Line Driver Output to AMT303 Commutation Encoder Series

CUI Inc announced a new addition to its high resolution, low-cost AMT encoder line with the AMT303LD series. The encoder generates standard U/V/W commutation signals for vectoring current to brushless motors.  Resolution can be set through the AMT303 Demo Kit.  Commutation output can accommodate brushless motors with 2, 4, 6, 8, 10 or 20 pole pairs, and is also selectable via the AMT303LD Demo Board.  The AMT303LD offers complimentary incremental A/A, B/B, and Z/Z channels for various servo positioning and startup sequences.  Additional options include nine mounting patterns and ten bore sizes, creating a flexible platform that is able to accommodate many industry standard motors.

The AMT303LD generates position information using CUI’s patented, capacitive code generation system coupled with a proprietary ASIC.  This technology is immune to environmental particulates and magnetic interference, creating a reliable, economical and stable control and positioning solution.  The encoder consumes a maximum 10 mA at 5 Vdc, making it ideal for any application where power consumption is a concern.

Commutation zero position may be set by the demo board, OTZ module or ground trigger, removing the need for time consuming mechanical alignment in the mounting process. The available AMT303LD Demo Kit includes an AMT303LD encoder, demo board, interface cables, documentation software and power supply.

CUI Launches Updated Website for AMT Encoder Series

TUALATIN, OR – CUI Inc announced that it has launched a new version of amtencoder.com, a website dedicated to their proprietary AMT modular encoder series. The site now features detailed product pages, a resource area with technical documents, videos, frequently asked questions, a news section, and an inventor’s bio. CUI’s VP of Marketing Jeff Schnabel commented, “Users of the new amtencoder.com can expect to find a wealth of resources on this exciting technology and the products that utilize it.”

The AMT encoder has been designed with proprietary, capacitive, code-generating technology that represents a breakthrough in cost vs. resolution. Capacitive technology holds numerous advantages over the optical technology typically used in today’s modular encoders. The AMT’s design allows users to select from a range of resolutions via an on-board dip switch, creating flexibility for companies utilizing multiple encoders in their applications. Additionally, common problems associated with optical encoders, including fragility of the optical disk, LED burn-out, limited temperature range, and high current consumption are eliminated by capacitive technology.

The AMT is available immediately through Digi-Key starting at $29.95 for 1 piece. Contact CUI directly for OEM quantities.

CUI’s AMT Encoder to be Paired with DC Motors from MicroMo

CUI Inc announces that their AMT Series modular encoder is now being carried by MicroMo Electronics, Inc., the North American distributor for the Faulhaber Group. The AMT utilizes CUI’s proprietary capacitive technology, which holds numerous advantages over the optical technology typically used in today’s modular encoders. The AMT’s design allows users to select from a range of resolutions via an on-board dip switch, creating flexibility for companies utilizing multiple encoders in their applications. Additionally, common problems associated with optical encoders, including fragility of the optical disk, led burn-out, limited temperature range, and high current consumption are eliminated by capacitive technology.

The AMT has been paired with several MicroMo DC motors ranging from 22 to 32 mm diameters and is being sold as a value added package. Dodd Disler, MicroMo’s Vice President and COO observes, “CUI provides a competitive encoder solution using unique technology. This provides another great tool for MicroMo to integrate into our custom motion solutions and value added drive systems.” The combination of the AMT and the MicroMo DC motor is ideal for indication and control of shaft velocity and direction of rotation as well as for positioning. The AMT102 is configured with a side or radial exit connector and the AMT103 is configured with a top or axial connector. The supply voltage for the encoder and the DC motor, as well as the output signals, are interfaced with separate cables for connection.

Matt McKenzie CUI’s President states, “MicroMo is an industry leader in its space and CUI greatly values their partnership.”

16 Dip Switch Programmable Resolutions

The AMT102 or 103 VersaPak model comes standard with an onboard dip switch with 16 selectable resolution options ranging from 48 to 2048 PPR.

It also includes an index pulse as standard. The output is TTL voltage and the operating temperature is -40° C to 100° C. The AMT is available in two mounting options: AMT102 is radial (straight orientation) and AMT103 is axial (right angle orientation). The AMT is capacitive and not optical, which eliminates handling of the sensitive optical disk and issues related to LED burnout from the photo diode.
