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 Electroswitchs cost-effective, automated production processes to build in quality performance.

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 users 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 Electroswitchs 36 mechanical detent positions that provide up many years of technological expertise in this to 36 electrical outputs per revolution in area. The resistive outputs are available in 5K or standard offering. Without mechanical detents, 10K linear tapers custom outputs can be the resolution per rotation can be much higher. developed upon request. All of these variations Electroswitch offers up to 96 electrical outputs are offered in the same package size and may per revolution in this non-detented method in be used in any combination. The typical custom applications. absolute code is either gray or binary. The four Several options within the 700 Series or five bit output gray code provides the benefit make it unique and a valuable choice for any of only one bit change per change of state. user. Our push-button feature allows two The incremental output code is known functions to be controlled by one shaft. By as an A/B counting code. As the shaft is rotated, integrating the push-button function into its two wave forms are generated and the A/B standard design, Electroswitch has been able code counts these pulses, sending them to the to keep the package size the same for all of the microprocessor to determine a relative 700 Series products. This push-button feature is position. The counts or pulses continue with the ideal for scrolling and select functions, or to rotation of the shaft, which allows the position incorporate an on-off option in one rotary to change infinitely, or as the microprocessor package size. allows.
