UNSPSC 32111601: Photo sensitive transistors

UNSPSC 32111601 Photo sensitive transistors is a Commodity code that encompasses electrical components and control system parts procured by state and local governments for utility infrastructure, facility management, and transportation systems. Recent solicitations under this code reflect procurement of specialized electrical components including protection relays, control panels, motor control centers, solenoids, ballasts, capacitors, and Schneider Electric components — parts that state and local buyers source for SCADA systems, pump station controls, water treatment facilities, utility distribution networks, and facility maintenance. The code draws solicitations from county utility authorities, municipal water departments, transit authorities, school districts, and county procurement offices across multiple states. Kissimmee Utility Authority in Florida, Hillsborough County Board of County Commissioners in Florida, Gwinnett County in Georgia, Trinity Metro in Texas, and Northside Independent School District in Texas have all posted recent opportunities under or aligned with this code's scope.

Recent activity spans Florida, Georgia, and Texas, with Florida showing the heaviest concentration.
