STI Minisafe MS4328BX is a 28-inch light curtain transmitter that acts as the sending half of STI’s safety beam pair. It specifies a minimum detectable object size of 0.75 inches (19 mm) and a sensing range of #205672, supporting reliable detection along typical factory beam paths. Designed for industrial safety applications, it pairs with STI receivers to guard machinery such as presses, conveyors, and robotic cells, triggering safe-stop or interlock signals when the beam is interrupted. This transmitter is built for mounting in standard safety installations within STI’s Minisafe light curtain system.
