applications 700 series mechanical encoders 700 series application notes with the introduction of the 700 series mechanical encoder and potentiometer, electroswitch delivers a low cost, multifunctional rotary interface with repeatable torque and feel to match the users needs. new to the 700 series is the addition of resistive (analog) output. therefore, users have the unprecedented option of choosing between two types of outputs; digital or resistive. the digital outputs are available in absolute or incremental code, and reflect electroswitchs many years of technological expertise in this area. the resistive outputs are available in 5k or 10k linear tapers; custom outputs can be developed upon request. all of these variations are offered in the same package size and may be used in any combination. the typical absolute code is either gray or binary. the four or five bit output gray code provides the benefit of only one bit change per change of state. the incremental output code is known as an a/b counting code. as the shaft is rotated, two wave forms are generated and the a/b code counts these pulses, sending them to the microprocessor to determine a relative position. the counts or pulses continue with the rotation of the shaft, which allows the position to change infinitely, or as the microprocessor allows. direction may be determined by analyzing the phase difference between the two channels. the a/b code is also known as a quadrature. in full quadrature, each change of state in the two waveforms is counted, providing the highest form of resolution at 4 counts per cycle. in half quadrature, only the changes of state in one wave form are counted, providing 2 counts per cycle. while in quarter quadrature, only the rise in one wave form is counted, providing 1 count per cycle. the 700 series features 12, 16, 24, 32 or 36 mechanical detent positions that provide up to 36 electrical outputs per revolution in standard offering. without mechanical detents, the resolution per rotation can be much higher. electroswitch offers up to 96 electrical outputs per revolution in this non-detented method in custom applications. several options within the 700 series make it unique and a valuable choice for any user. our push-button feature allows two functions to be controlled by one shaft. by integrating the push-button function into its standard design, electroswitch has been able to keep the package size the same for all of the 700 series products. this push-button feature is ideal for scrolling and select functions, or to incorporate an on-off option in one rotary package size. standard mounting configuration is shaft perpendicular to the mounting board, with a bracket for additional mounting strength. 8
