STI MS46-30-1215-Q1-X Light Curtain Transmitter

STI MS46-30-1215-Q1-X Light Curtain Transmitter is a Mini Safe 4600 Series safety device from STI (Omron Automation & Safety) that acts as the transmitter half of a two-beam safety light curtain used for machine guarding in industrial automation. Designed to pair with the MS46-30-1215-R-FP-CX1 receiver (sold separately), this transmitter carries the MS46-30-1215-Q1-X part number and is described by distributors as a SPARE TRANSMITTER for the MS46-30-1215 family. The unit’s compact footprint measures 2.0 in × 1.5 in × 2.0 in (5.1 cm × 3.8 cm × 5.1 cm) and it is manufactured in the United States as part of the Mini Safe 4600 series. Distributors list the MS46-30-1215-Q1-X as a SPARE TRANSMITTER for this line, and major catalogs note that the model is obsolete, indicating it is no longer in production. This transmitter works with the corresponding MS46 receiver to deliver rapid safety signaling in perimeter guarding, robot cells, and other industrial automation applications that rely on a 30-mm beam array for protective sensing.
