EX-21A Overview

For reliable performance, the temperature of the photoelectric sensor should be set to -25°C~55°C. For these electronic components to function, a voltage of 12V~24V should be applied to a circuit or system. Photoelectric sensors are designed to operate with a current of 50mA at the output. The photoelectric sensor is not damaged by voltage of 24V applied in DC circuit. This photoelectric sensor can work at as low a voltage as possible, such as 12V.
