Industrial FS4324BX-3 Light Transmitter 24 Inch

STI FS4324BX-3 FlexSafe-B FS4300 Series Light Transmitter is a 24-inch light curtain transmitter from Scientific Technologies Inc., designed for use in FS4300 safety light curtain systems. This used-surplus unit is listed under 42675-0240 with the USNP configuration and is marketed as a working transmitter within the FlexSafe-B family, intended to pair with a compatible receiver to form a complete safety light curtain for industrial guarding. The 24-inch length aligns with FS4300 installations on equipment such as conveyors, presses, and other automated machinery, where beam interruption triggers a safety response and the transmitter provides the beam path to the receiving segment. The FS4300 family uses specific cabling; for example, documentation notes 4.6 m transmitter cables and 1.5 m receiver cables to connect transmitter and receiver segments, with 24-inch segments standard for this family, and when selecting this model you should verify compatibility with your FS4300 receiver segment and follow STI FS4300 installation guidelines to ensure proper alignment and guarding performance.
