Leveraging on each other’s industry-leading technologies, engineers at Avago and MicroMo Electronics, a FAULHABER affiliate in the US, collaborated to design the PA2-50, which is the smallest optical encoder in the industry. The PA2-50 was designed with the AEDR-8400 chip on a flex-circuit to produce a single compact package with a miniature footprint measuring 3.00mm (L) x 3.28mm (W) x 1.26mm (H). The motor connections were integrated into the flex circuit to ensure a compact solution. Additionally, with the miniature AEDR-8400 optical chip, higher resolution can be achieved to meet the design requirements for a wide range of applications that require miniature motors with high precision positioning
The 8 mA at 3 V DC power consumption enables battery-operated applications to operate longer than the conventional 5-Volt encoders that are used by most competing brands. The end result is an ultra miniature rotary encoder solution with higher resolution, a more consistent signal, and higher efficiency due to lighter codewheel material, while ensuring low current consumption for a longer lasting battery-assisted operation.
Avago’s AEDR-8400 series are reflective technology encoders that have been designed with a transmitter and emitter located on the same SMT surface with a reflective codewheel to reflect, thus enabling the encoder solution to be much smaller than conventional optical encoders that use transmissive technology.
