High-quality safety light curtains provide reliable protection for workers operating heavy machinery, effectively preventing workplace accidents. Therefore, partnering with a professional and reputable safety light curtain manufacturer is crucial.
In this blog post, based on our extensive experience, we will recommend 13 trustworthy, top-tier global safety light curtain manufacturers. (We previously wrote a blog post focusing solely on Chinese safety light curtain manufacturers and suppliers, but we now believe that article had limitations and didn’t provide comprehensive information if you’re looking to source locally, so we’ve written this new post for your reference.).
All these manufacturers not only offer reliable products but also provide detailed solutions tailored to your specific needs.
Now, let’s delve deeper!

Allen-Bradley was acquired by Rockwell Automation in 1985. Allen-Bradley offers as many as 52 different models of safety light curtains. They primarily produce safety light curtains with two resolutions: 14mm and 30mm. The 14mm resolution safety light curtains are used for finger protection, while the 30mm resolution safety light curtains are used for hand and body protection.
Furthermore, Allen-Bradley safety light curtains range in protection height from 150 mm to a maximum of 1950 mm, making them suitable for most types of machinery on the market.
6. Reer safety light curtain (Italy)
- Address: 10153 Torino, Italy
- Certificate: CE, UL, CSA, UKCA, RoHS, REACH
- Website: https://www.reersafety.com
Reer is a Italian safety light curtain manufacturer, they provide 7 different series safety light curtains, namely EOS2, EOS4, SAFEREADY, Admiral, Janus and MXL series.
If you are confused with their safety light curtains, here are the 7 different series differences:
- Entry-level economy model: EOS2,
- Mid-range compact and practical model: EOS4,
- High-end smart Bluetooth model: SAFEREADY,
- Long-range high-risk mainstay model: Admiral,
- Highly integrated blanking-specific model: Janus,
- Class II security universal model: MXL.
Therefore, if you want to easily adjust and monitor the safety light curtain remotely by a mobile phone, Reer’s newly developed SAFEREADY is a good choice, which other brands do not offer.
7. IFM light curtain (Germany)
- Address: 45128 Essen, Germany
- Certificate: CE, cULus, TÜV, RoHS, REACH
- Website: https://www.ifm.com
IFM is a German manufacturer of safety light curtains, providing high-quality, highly reliable finger, hand, and body protection products. Their finger safety light curtains have a resolution of 14 mm, their hand protection products have a resolution of 20 mm, and their body protection products can be configured with resolutions of 300 mm, 400 mm, or 500 mm.
I was particularly impressed with their safety light curtains featuring a floating blocking function. When this function is enabled, workpieces of preset sizes and continuity can pass smoothly through the protected area without triggering an emergency stop. Simultaneously, if an unexpected object (such as a hand or arm) enters the safe area beyond the permissible blocking range, the machine will still stop immediately.
We can think of it as a fishing net: it allows workpieces within a set maximum size range to pass through smoothly, but any object larger than the allowed size, or any discontinuous object entering the protected area, will trigger a safety stop. It’s important to note that this function only reacts to the size and continuity of the object, not its properties; therefore, it can only be used in fully automated applications.
8. Orbital safety light curtain (India)
- Address: Nashik, Maharashtra, India
- Certificate: CE, RoHS, REACH
- Website: https://orbitalmekatronik.com
Orbital is an Indian manufacturer and supplier of safety light curtains, offering Type 2 and Type 4 safety light curtain sensors.

Depending on resolution, their safety light curtain sensors are available in four sizes: 10.0 mm, 18.25 mm, 18.37 mm, and 36.75 mm.
In addition, Orbital also supplies incremental rotary encoders. However, according to our customs investigation, their incremental rotary encoders are not manufactured in-house, but rather sourced from Chinese suppliers and resold to customers in India.
9. Banner safety light curtain (United States)
- Address: Plymouth, MN 55441, USA
- Certificate: CE, cULus, UKCA, RoHS, REACH

Banner, a company with a long history in security, began its business in 1991.
Banner’s finger protection safety light curtain has a resolution of 14 mm, while its hand protection products have resolutions of 23 mm, 25 mm, and 30 mm, and its arm protection products have a resolution of 40 mm. In comparison, Lorentzzi’s finger protection has a resolution of 10 mm, and its hand protection has a resolution of 20 mm. Banner’s optical axis spacing is slightly larger, which may be because its products are mainly targeted at the European and American markets.
