High-Resolution "Tough Guy" Magnetic Rotary Encoders Beat Opticals on Reliability and Application Versatility



New 10, 11 and 12-bit Renishaw RM miniature rotary encoders combine non-contact, long-wearing rugged design with easy integration

January 2004 - New Renishaw 10, 11 and 12-bit RM miniature magnetic rotary encoders provide a "tough guy" alternative to high-maintenance glass encoders. The industrialized designs bring low maintenance operation, lifetime reliability and tremendous application versatility to problem applications. The non-contact magnetic encoders deliver high-resolution positioning (up to 4,096 count) to over 9,000 rpm with accuracy to 0.4°. Maximizing integration possibilities, the versatile product range includes component, modular and packaged shaft-style models. Outputs include low-cost absolute versions with parallel or serial data formats, as well as versions with incremental (1,024 ppr), analog, linear voltage and linear current outputs.

Created for the widest spectrum of industrial applications, Renishaw's RM magnetic encoders provide excellent shock and vibration resistance, with an extended operation temperature range of -25°C to 125°C (-12°F to 195°F). Models are available with sealing to IP68 for harsh environments, including immersion applications (e.g. pumps and gearboxes). Non-contact magnetic design eliminates seals, bearings and all moving parts for superior long-term reliability. Compact size and design simplicity enables easy installation and setup. Power requirements are half or less than that of optical encoders.

The ruggedness, reliability and cost economies of Renishaw's RM magnetic rotary encoders can save OEMs on the front-end and on service/repair costs, particularly over glass optical encoders. The extensive model line and configuration options allow use in a wide range of industries - automation, motor feedback, office equipment and electronics, household appliances, medical equipment, flow/metering/dispensing control in process industries, marine instrumentation, lift and construction equipment, printing equipment and vending machines. Linear voltage or current output versions can be used in applications such as panel switches, where traditionally potentiometers have been used.

The new high-resolution versions join the 9-bit (512) magnetic rotary encoders introduced in early 2003 by Renishaw for North American markets. Renishaw backs the RM lines with local inventory and a worldwide support network. Custom mounting configurations are possible for large-volume orders.
