Reflective Object Sensor- Optical Proximity Switch Using PLL LM567 The simple circuit is based on LM567 PLL IC and optical sensor QRD1114 from Fairchild semiconductor. The QRD11114 reflective sensor consists of an infrared emitting diode and an NPN silicon photo Darlington mounted side by side in a black plastic housing. The on-axis radiation of the emitter and the on-axis responseRead more
Dual-Channel Quadrature Hall-Effect Bipolar Switch Module For Magnetic Encoder for Motion Control application.
Dual-Channel Quadrature Hall-Effect Bipolar Switch Module For Magnetic Encoder for Motion Control application. The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photolithographically aligned to better than 1 µm. Maintaining accurate mechanical location between the two active Hall elements eliminatesRead more
