EZ-SCREEN® LS light curtains are intuitive, easy-to-use safety devices used for machine safeguarding. They are built to withstand challenges commonly found in manufacturing and packaging environments. Heavy-duty aluminum housing and recessed window ensure the emitter/receivers avoid damage in harsh environments. The no blind zone design provides end-to-end sensing to eliminate gaps in detection.

Trip Output for Safe Operation

LS-S models have trip output (auto power-up and automatic reset). In typical operation, if any part of an operator’s body, or any opaque object, of more than a pre-determined cross section is detected, the solid-state output signal switching device (OSSD) safety outputs turn off. These safety outputs are connected to the guarded machine’s final switching devices (FSDs) that control the machine primary control elements (MPCEs), which immediately stop the motion of the guarded machines.

Quick and Easy Configuration

LS-S models require no PC software, DIP switches, or other devices for quick, easy configuration. Highly visible alignment indicators and intuitive diagnostics simplify setup, facilitate troubleshooting, and minimize system downtime. LS-S models are extensively FMEA (Failure Mode and Effects Analysis) tested to establish an extremely high degree of confidence that when properly installed, no system component, even if it should ever fail, can cause a failure to danger. Because of the dual screen technology, EZ-SCREEN LS sensors are highly immune to EMI, RFI, ambient light, weld flash, and strobe light.


LS-S Models can be used for, but are not limited to, the following applications:

  • Automated production equipment
  • Robotic work cells
  • Molding and power presses
  • Assembly and packaging machines
  • Lean manufacturing systems
