Industrial MS4328B-2 Light Curtain Receiver Module

The STI MS4328B-2 MINISAFE-B 28" light curtain receiver is the receiver component of the MINISAFE-B MS4300B-2 safety light curtain family, designed for machine guarding in industrial automation. It provides 28 inches of coverage height and a sensing range up to 30 feet, enabling reliable detection of beam interruptions across the curtain when paired with the corresponding transmitter, MS4328B-2-T. The MS4328B-2 is part of the MS4300B-2 series, a two-piece light curtain setup commonly used to guard automated equipment such as presses, robotic cells, conveyors, and packaging lines. The receiver interprets beam breaks and feeds the signal into the machine’s safety logic, supporting straightforward retrofit applications while helping maintain continuous workflow in busy manufacturing environments. The beam spacing for this family is 0.5 inches, which supports precise detection across the 28-inch curtain and consistent performance across the sensing area. In typical installations, it pairs with the MS4328B-2 transmitter to form a complete 28-inch safety curtain, delivering a practical solution for upgrading machine guarding to modern safety standards.
