E3S-BT81 Overview
For reliable performance, set the temperature of the photoelectric sensor to -25°C~55°C. To make these electronic components function, they should receive a voltage of 12V~24V. An ideal response time for photoelectric sensors is 500μs. Sensors need to work at -25°C to be reliable. For reliable operation, the maximum operating temperature is 55°C. Photoelectric sensors should have their supply voltage set to 0.
