Industrial MS4320B-2 Light Curtain Transmitter

The STI MS4320B-2 Light Curtain Transmitter is a 20-inch Minisafe-B safety beam element designed to be paired with a matching MS4320B-2 receiver to form a protective optical curtain around hazardous machinery. It operates on standard 115 VAC input at 50/60 Hz and draws about 0.25 A, aligning with typical Minisafe-B components for reliable guarding in industrial automation. Used as the transmitting half of STI’s Minisafe-B light curtain system, the MS4320B-2 transmitter guards access points on equipment such as robotic cells, presses, and conveyors, enabling immediate shutdown when the beam is interrupted along the guarded zone.
