Optical Encoder Fits in Tight Spaces

The new QM22 series of incremental optical encoders from Quantum Devices Inc. measures just 22-mm in diameter and a 12.4-mm thick. It fits on a NEMA 11 BLDC servo motor and can replace the obsolete Heidenhain/Renco R22i encoder line. It is capable of high precision positioning and is available with line counts up to 2500. Commutation output options including 4, 6, or-8 pole configurations eliminate the necessity for additional external commutation peripherals such as Hall Boards. Immunity from EMI/RFI noise greatly extends the range of suitable applications in which the QM22 series can be incorporated. The QM22 uses a modular, bearingless design that features an easy to install Lock-n-Twist assembly method. It has a hermetically sealed LED and complies with REACH and RoHS.
