Product Information

The iC-LSC sensor array, coming with 12 independent channels, is a general purpose optoelectronic scanner made to suit a variety of encoding applications, such as rotary and linear encoders used for motion control, robotics, brushless DC motor commutation, power tools etc.

The sensor array features monolithically integrated photosensors with active areas of 800μm x 300μm each in combination with fast on-chip photocurrent amplifiers, enabling an analog output at reasonable signal strength to the circuit board. The highside current source output construction avoids a ground referenced signal and permits the subsequent electronics to adjust the gain. In its simplest form this is done by load resistors, for instance.

The spectral sensitivity range includes visible to near infrared light, with the maximum sensitivity being close to a wavelength of 700 nm.

Output currents of up to 50 μA are supplied under low light conditions, for instance when illuminated at only 3μW/mm2 by an 850nm LED. The photocurrent gain is 46 dB typically.
