As the latest version in our new generation of rotary encoder products, the 700 Series selection. has been freshly tooled to include resistive analog HVAC TEMPERATURE AND output for potentiometer applications, as well as the standard digital code for direct interface with a FAN CONTROL microprocessor. The .890” package enhances the Digital or analog output for temperature original design concept, delivering high performance with direct drive to display and fan control and quality levels in the triple digit PPMs. for automotive use. Electroswitch leads the market in rotational torque management for encoders. Our process includes ELECTRONIC RANGE CONTROL digital maps to ensure repeatable and quantitative measurement. Control of bake time, temperature and Newly introduced in the 700 Series in an integrated duration in residential and commercial push-button, which permits two functions in a single applications. shaft. This feature provides system cost savings and user-friendly interface for input selection. The push- button feature is offered in the same package size as the standard 700, with a complete interface for PANEL INPUT DEVICE scrolling through a menu and making a selection. Used to scroll through menu via shaft The 700 Series features a wide range of standard rotation; for selecting menu item via push- configurations to fulfill most needs. As with standard button. product, customized versions for volume applications also benefit from Electroswitch’s cost-effective, automated production processes to build in quality performance. AUDIO INPUT Volume control for all amplifier applications; automotive, musical, home, and professional. SERIES MECHANICAL 700 ENCODERS 700 Series Application Notes With the introduction of the 700 Series The A/B code is also known as a Mechanical Encoder and Potentiometer, quadrature. In full quadrature, each change of Electroswitch delivers a low cost, multifunctional state in the two waveforms is counted, providing rotary interface with repeatable torque and the highest form of resolution at 4 counts per ‘feel’ to match the user’s needs. cycle. In half quadrature, only the changes of New to the 700 Series is the addition of state in one wave form are counted, providing resistive (analog) output. Therefore, users have 2 counts per cycle. While in quarter quadrature, the unprecedented option of choosing only the rise in one wave form is counted, between two types of outputs; digital or resistive. providing 1 count per cycle. The digital outputs are available in absolute or The 700 Series features 12, 16, 24, 32 or incremental code, and reflect Electroswitch’s 36 mechanical detent positions that provide up many years of technological expertise in this to 36 electrical outputs per revolution in area.
