Safety light curtains are opto-electronic safety devices used for machine safeguarding. Light curtains protect plant personnel by guarding the dangerous point of operation and nip points of industrial machinery.
Our safety light curtain products offer:
- Low cost
- More features than the competition
- Long product warranties
- Quick delivery
Pinnacle Systems light curtains are Type 4 / Category 4, SIL 3, PLe, control reliable, and proudly made in USA.
Designed, Manufactured, and Supported by Pinnacle Systems
Pinnacle Systems designs, manufactures, and provides service after the sale of our family/series of safety light curtains.
When properly installed, a safety light curtain protects the machine operator and passerby by sending a series of invisible infrared light beams across an area to be guarded, determining whether or not the light beam(s) are blocked.
Our safety light curtains have been time-tested to be:
- Extremely dependable
- Feature intensive
- Cost-effective for complex machine safeguarding projects
All while protecting your most valuable resource — the employee.

Protecting Operators While Improving Production
Our light curtains provide assurance to both employers and machine operators that hazardous areas and dangerous points of operation can be safely guarded. Common applications include:

Power press guarding and controls

Press brake guarding

Robot guarding

Automation guarding
Operator safety is our priority while effectively maintaining product quality, backed by our long product warranties.
Properly designed and interfaced light curtains can have an extremely positive impact on production throughput.
We have also blended artificial intelligence (AI) into our light curtain system diagnostics to identify system faults that may arise over time. This saves time and enhances overall equipment efficiency (OEE) for front-line supervisors.
