UNSPSC 39122230: Proximity switch

UNSPSC 39122230 Proximity switch is a Commodity code that spans electrical switches, switching devices, and related control equipment used in infrastructure and operational systems, though recent state and local solicitations show activity heavily skewed toward network switches, power distribution components, and specialized switching hardware rather than proximity sensors per se. State and local governments are procuring network switch installations, replacement of end-of-life switching infrastructure at airports and transit facilities, electrical contact kits for motor control applications, mercury float switches for water system pump triggering, solenoid lock switches for transit access, and electrical switch supplies on master-agreement and as-needed bases. Issuing bodies span city departments (Atlanta Department of Aviation, City of Dallas, City of Charlotte), county water and transportation authorities (Hillsborough County Water Resources Department, Dallas Area Rapid Transit Authority), school districts (Northside Independent School District in Texas, Gordon County School System in Georgia, Bibb County Public Schools in Georgia, Eugene School District in Oregon), state departments (Texas Department of Criminal Justice), and special-purpose cooperatives (Sourcewell on behalf of multiple Washington counties). Repeat buyers include Hillsborough County (three solicitations for switches and electrical components in January–February 2026) and Dallas Area Rapid Transit Authority (multiple component procurements in February 2026).

Recent activity concentrates in Texas, Florida, Georgia, and the upper Midwest, with secondary activity in Connecticut, Oregon, and Washington. Representative recent opportunities include the City of Atlanta Department of Aviation's IFB PE66062NONST2026000000436 for NEMA switch upgrade labor and installation at Hartsfield-Jackson International Airport (due August 3, 2026); Hillsborough County Water Resources Department's ITB2600138 for mercury float switches (due March 2, 2026) with an estimated contract value of $60,000 over two years; Dallas Area Rapid Transit Authority's ITB 2099242 for a solenoid lock switch with controller transformer (due May 20, 2026); Northside Independent School District's IFB2026098 for electrical equipment, parts, supplies, and services (due July 1, 2026), replacing an expiring contract; and the City of Dallas's BE2600029715 for a sixty-month master agreement on electrical supplies (due March 13, 2026) with local preference provisions allowing up to 5 percent preference margin for Dallas-based firms.
