Reviews for Safety Light Curtains (Category 4 / Type 4)

Outstanding light curtain. Easy to setup and use. Good documentation for device. Highly recommend. Does not come with cable. Don't forget to include when purchasing.

The instruction manual could use a better wiring diagram and a clearer explanation of what each wire's function is. Installed smoothly and aligned on the first try. Purchased these to replace IFM curtains that lasted almost 10 years...hopefully these will last as long!

Great product, ease of install. I combined this with recommended LG5925-48-900-61 Dold Safety Relay. Overall very easy setup and install. Two thumbs up

Used in application 30" apart, easy to align and set-up

Used in application 30" apart. Easy to align and set-up.

We use these light curtains to stop machine operation if operators reach into an area they should not, and the area not a good candidate for another type of guarding, such as a door. These are easy to set-up, and were paired with the Dold LG5925-48-900-61 safety relay. We used the relay in the Auto-restart mode, so you must be sure that both switches in the safety relay are in the up position.

These light curtains are a great value, however, if you do not have the alignment laser, part number YXL-0001-000, installation can be time consuming and difficult. The alignment tolerance is very tight compared to other light curtains I have used in the past. Also, if the light curtains are installed in an area where they are susceptible to being bumped, I recommend installing some type of guarding to protect them as they are thrown out of alignment very easily.
