The 3SG series safety light curtains are designed with independent dual-loop output mode, featuring self-check function of output circuits and over current protection function. We use unique optical lens design, enabling the maximum distance of photoelectric sensor reflection to reach over 30 meters. The working voltage of the safety light curtains is DC 10V - 30V, with a wide voltage supply range. The output is in the form of transistor, which can be directly connected and used with PLC or relays. The housing use double-sided sliding slot installation design, facilitating the diverse installation of the safety light curtains. The beam range is maximum reaching up to 30M. Use dual-loop self-check output design,High safety and reliability. It has strong anti-electromagnetic interference capability. The aluminum alloy shell structure design has good seismic resistance. It adopts line synchronization technology and has strong anti-light interference ability. It is suitable for installation and use in various environments.
