Miniature inductive rotary encoder works with gear teeth
Posic is launching a highly miniaturised inductive rotary encoder, known as the ID1101G, for gear-wheel scanning. The encoder head measures only 9.0 x 6.8mm, with a thickness of 0.9mm, and provides A and B pulses in quadrature. The pulse-frequency ranges from zero up to 200kHz. The extremely small dimensions enable the encoder to be integrated inside spindles, drives and electric motors. The encoder scans gear teeth of different materials with modules 0.4 to 0.7. In order to achieve the best possible resolution, a pulse-multiplication factor ranging from x1 to x64 can be selected.The main features of this encoder are said to be its extremely small dimensions and its insensitivity to dust, water, oil, grease and even magnetic fields.
OSIC says the ID1101G encoders will typically be used in applications such as machine-tools, assembly equipment, industrial robots and welding equipment.
Evaluation kits containing two cabled encoders, a gear and an interface board are available from stock.
