Rotary Encoder Exhibits Small Footprint
Being billed as the world’s smallest, Avago Technologies’ and the FAULHABER Group’s PA2-50 rotary encoder measures 3 mm × 3.28 mm × 1.26 mm. The component incorporates the AEDR-8400 optical IC with a transmitter and emitter located on the same SMT surface. The motor connections are integrated into the flex circuit. The 6-mm D unit demonstrates power consumption of 8 mA at 3 VDC, making it suitable for battery-operated applications that require miniature motors with high precision positioning.
