Control your lighting costs with photocells and occupancy sensors.

Sensors are the smart solution for minimizing energy consumption and maximizing lighting system life. Utilizing state-of-the-art electronics and optics, Keystone’s line of occupancy and photocell sensors provide a cost-effective solution for dramatically improving your return on investment.

Our photocell sensors utilize an industry-leading compact design to enable installation into small enclosures and fixtures. Available in low (45VA) and high (80VA) power versions, Keystone’s photocells cover most application needs. These sensors are compatible for use with LEDs, fluorescent ballasts, and incandescent lamps.

Ensure your high bay lighting systems are only on when they need to be.

Keystone’s occupancy sensors intelligently signal when to turn the lights on and off. When someone enters the coverage area of the passive infrared sensor, the lights will turn on. You have the power to decide when they shut off after a designated amount of inactivity. After installing Keystone sensors, customers commonly save up to 80% on electricity usage and extend the system life over two years.

Keystone offers interchangeable fresnel lenses for even more control of your high bay lighting systems. The 360° lens view covers a circular area underneath the high bay fixture. The aisle-way lens view focuses the coverage on the open aisle, not where the racks are. This provides enhanced performance with less passive infrared sensors needed. Keystone also has you covered for outdoor sensor needs with our wet location high bay occupancy sensors.
