摘要： A photoelectric sensor includes: a first signal processing chain including a first amplifier configured to amplify an output signal from a preamplifier by a first amplification factor A1 and a first binarization circuit configured to binarize an output signal from the first amplifier by a first threshold Vthl; and a second signal processing chain including a second amplifier configured to amplify an output signal from the preamplifier by a second amplification factor A2 and a second binarization circuit configured to binarize an output signal from the second amplifier by a second threshold Vth2. The first threshold and the second threshold, and the first amplification factor and the second amplification factor satisfy the following relational expression: 1
