You should set the photoelectric sensor's temperature to -20°C~55°C for reliable performance. This electronic component must have a voltage of 0 in order to function in a circuit or system. It is generally considered that photoelectric sensors have a response time of 3ms. Photoelectric sensors need 100mA at their outputs to work. The photoelectric sensor can withstand a maximum voltage of 30V in a DC circuit without sustaining damage. Photoelectric sensors work at as low a voltage as possible, for example 10V.
