To maintain reliable performance, the photoelectric sensor should have a temperature of -10°C~55°C. In order for these electronic components to function, the voltage should be set to 24VDC within the circuit or system. When it comes to photoelectric sensors, a response time of 4ms is ideal. For photoelectric sensors to work, they have to be at -10°C. Reliability is ensured by operating at a temperature of 55°C maximum.
