The SICK WSU 26-220 photoelectric sender is an optic electronic emitter used in industrial sensing systems to generate the light beam for photoelectric detection. It operates on 110–120 VAC at 48–62 Hz, delivering the required supply for compatible SICK receivers. As the emitter in a photoelectric sensing pair, this model is designed to be paired with a matching receiver to complete a sensing setup for object presence or absence in automation environments.
