UNSPSC 32121610: Thermistor

A type of resistor used to measure temperature changes, relying on the change in resistance with changing temperature.

UNSPSC 32121610 Thermistor is a Commodity code that encompasses temperature-sensing components and related electrical control devices used in industrial and utility infrastructure. Recent state and local procurement activity under this code shows minimal direct thermistor sourcing but substantial activity in electrical components and control systems that incorporate or require thermistor-level sensors and controls. The issuing bodies soliciting under related electrical component and control codes include utility authorities, county governments, school districts, and transit authorities. Kissimmee Utility Authority (KUA) in Florida solicited SEL 451 and SEL 751 protection relays for electrical system upgrades under a sole-source procurement (RFQ SS26054SH, due August 24, 2026), with relays integrating temperature and overcurrent protection functionality. Hillsborough County, Florida issued an ITB (ITB2600277, due June 18, 2026) for ongoing Schneider brand electrical components valued at $519,787.19 over two years, and a separate ITB (ITB2600393, due September 29, 2026) for pump station control panels estimated at $3.66 million over two years, where embedded thermal and control sensors are core to panel functionality. Northside Independent School District (San Antonio, Texas) solicited electronic equipment, parts, repairs, and services through an IFB (IFB2026118, due September 24, 2026) that explicitly includes electrical component sourcing.

Geographic activity concentrates in Florida and Texas, with secondary presence in Georgia and broader multistate activity through cooperative purchasing vehicles. Hillsborough County and Kissimmee Utility Authority represent repeat buyers of electrical control and sensing infrastructure in Florida. Gwinnett County, Georgia solicited ballasts and capacitors on an annual contract (PA028-26, due June 12, 2026) for approximately 200 units annually, and Trinity Metro (Tarrant County, Texas) sought to establish an IDIQ electrical parts supplier contract (IFB26T035, due August 20, 2026) for maintenance and emergency operations. The City of Tampa issued a same-day RFQ (26P00389, due June 19, 2026) for supply and installation of a surplus solenoid for a Zenith Automatic Transfer Switch, and the City of Fort Worth sought proposals for elevator and escalator maintenance (RFP 260225, due July 30, 2026). Sourcewell's cooperative purchasing RFP #061626 (due June 16, 2026) for law enforcement equipment represents a multistate initiative available to public entities across the United States and Canada. The code shows activity primarily among utility, county infrastructure, and school district buyers pursuing electrical control and sensing components as part of broader system upgrades and maintenance programs rather than standalone thermistor procurement.
