Slimline escap(R) A22 incremental encoders provide three-channel 500-line service in a package diameter of only 22 mm. A custom opto-electronic integrated circuit forms the heart of the units. Resistant to all forms of external disturbance, phase shift between the two quadrature output channels is barely affected by temperature. Encoders with up to 256 lines are also insensitive to motor endfloats of 0.15 mm. This means that expensive preloaded ball bearings are not required in many applications. The escap A22 units have a typical current draw of only 5 mA from its 5V supply. If the motor is known to be stationary, the encoder can be set to a standby mode. In this condition the output line status is retained and the current draw is only 5muA.
