XUSL Type 4 light curtains provide point of operation protection for large areas without the need for gates or guards. They allow excellent visibility of the machine or process and free access to the machine while providing protection for personnel. Light curtains are made up of an array of infrared light beams to form a protected area. Whenever one or more of the light beams is broken, the light curtain sends a stop signal to the machine safety control circuit.
XUSLT and XUSLM light curtains for point of operation safeguarding are available in two box and three box systems. Choose the one that best meets your application requirements. These versions are available in either 14 mm or 30 mm minimum object sensitivity (MOS). Fixed and floating blanking is standard on all devices as well.
Two box light curtains are ideal for installations where it is desirable to mount and wire only two components, transmitter and receiver. These devices are self-contained and the receiver provides the safety outputs. A separate control box is not required, reducing installation time and hardware.
Three box light curtains are used in installations that require the smallest possible footprint for the transmitter and receiver. The footprint can be smaller because much of the logic and all outputs for the light curtain are housed in a third box (or controller). The third box provides power to both the transmitter and receiver.
Perimeter guarding light curtains are used around work cells and for guarding around the perimeter of machinery. They are also used in place of gates or doors. These two box systems simplify installation, since no inter-wiring is required between the emitter and receiver. Installation is further simplified with the passive receiver version, which only needs to have the emitter wired. No wiring is required for the receiver.
