Industrial FS4312BX-3 Light Curtain Transmitter

The STI FS4312BX-3 is a 12-inch light curtain transmitter (emitter) in STI’s FlexSafe FS4300 safety line, designed to pair with a matching receiver to form a two-piece safeguarding system for machine guarding. This transmitter-only module sends infrared beams across a guarded gap and triggers the safety control when the beam is interrupted, with a 12" form factor and a sensing range specified as 1 to 30 feet, making it suitable for compact guard zones on a range of industrial equipment. As part of the FS4300 family, the FS4312BX-3 requires a compatible STI receiver to complete the light curtain and provide the full protective function, a common configuration for environments where automatic safeguarding of access points is required in manufacturing or fabrication settings. Ensure you verify exact receiver compatibility for your system to confirm proper performance and safety compliance.
