New Features for Cost-Effective Optical Encoders

July 19, 2016 08:59 AM

Following the success of the Series 62AG Encoder, Grayhill is launching G versions of their Series 62S and 62N Encoders. The new 62SG and 62NG are price competitive encoders that satisfy the most common requirements for human interface encoders.


The 62NG and 62SG Series Encoders are manufactured from 100% hard tooled piece parts and utilize a patented technology for optical switching. This is the same technology that has been field tested and proven reliable in the Series 62AG Encoder. These design enhancements enable the 62xG Range encoders to be price competitive, while providing superior reliability and performance. The optically-coupled switching in the Series 62AG, NG and SG enable the encoders to surpass one million rotational cycles, thus providing superior durability over corresponding mechanical encoders.

The new Series 62SG Encoder has a 0.3-inch (7.5mm) behind panel depth, making this compact encoder ideal for space saving applications. For a fully enclosed encoder, it also has one of the smallest footprints, at approximately a half-inch square (12.7 x 14.7mm to be exact). Despite this compact size, it still offers a distinct tactile feedback. There are even two options for rotational torque and pushbutton force. Finally, the 62SG has the widest temperature range of any compact, enclosed encoder. Combined, these features make the Series 62SG Encoder ideal for mobile applications such as navigation systems, dashboard assemblies and portable medical electronics.

A special feature of the Series 62NG Encoder is a separate non-rotating pushbutton shaft. This ensures that text or symbols printed on the pushbutton cap remain upright while the encoder knob is rotated. Series 62NG has more options for angle of throw and a wider operating temperature range than any of the competition. No other enclosed encoder can offer this same level of price and performance.

Grayhill encoders generate a two bit digital output to measure the magnitude and direction of the shaft or knob rotation.  Add the optional integrated push-button and these rotary encoders become the perfect device for scrolling items from a list or menu and selecting the desired function.  Designers of equipment in industries including medical electronics, test and measurement, and audio / video will find the 62xG Range Encoders to be an effective and competitive user interface solution. Custom shaft configurations and switch terminations are available in annual quantities exceeding 500 units.
