Light Curtains
Protect personnel from hazardous machines by creating a "curtain" of light energy between a transmitting and receiving pylon. If the curtain of light is penetrated, the receiving unit sends an electrical signal to stop the machine. Light curtains are available in a variety of sizes and resolutions (spacing betweent the beams of light).
