Industrial MS4300B-2 Light Curtain Transmitter

The MS4300B-2 Light Curtain Transmitter is STI’s Minisafe-B component that pairs with the MS4320B-2 Receiver to form a two-piece safety light curtain for guarding machine access in automated cells. This transmitter, part of the MS4300B-2 series, works together with the MS4320B-2 to monitor a safety beam and halt equipment when the beam is interrupted. Distributor listings describe the unit as an 8-inch module with a 120 VAC input at 50/60 Hz and a weight around 11.67 lb; the product is noted as discontinued by the manufacturer. Known as a DUOSAFE safety device, the MS4300B-2 is designed for industrial environments where reliable beam sensing helps protect operators around machinery such as presses, conveyors, and robotic work cells. Use this transmitter in conjunction with the MS4320B-2 receiver to complete the safety circuit and enable coordinated stop/guard functions.
