PSC 5945

Overview

The Product Service Code (PSC) system is a governmentwide taxonomy that standardizes how agencies classify what the U.S. government buys, supporting consistent entry, analysis, and reporting of contract actions in the Federal Procurement Data System (FPDS). The PSC Manual, maintained by GSA and published on Acquisition.gov, provides the official code set, definitions, and guidance for coding contract actions. ¹

PSC 5945 is the product class for Relays and Solenoids within Federal Supply Group 59, Electrical and Electronic Equipment Components. The manual defines 5945 as “Relays and Solenoids,” explicitly includes electromagnetic actuators, and specifies that the code is used when these items are the predominant products on the action. Agencies should select PSC 5945 when the principal deliverables are relays, solenoids, or electromagnetic actuators rather than broader electrical control equipment. ¹

  • PSC 6110

What this PSC covers

• Relays used to switch electrical or electronic circuits across defense, aerospace, industrial, and commercial applications. ¹
• Solenoids that provide linear or rotary motion for actuation and control functions in mechanical systems. ¹
• Electromagnetic actuators explicitly included under this class. ¹

Related NAICS and PSC codes

Type	Code	Descriptor
PSC	5940	Lugs, Terminals, and Terminal Strips
PSC	5950	Coils and Transformers
PSC	6110	Electrical Control Equipment
PSC	5999	Miscellaneous Electrical and Electronic Components

Key inclusions and exclusions

• Includes: Electromagnetic actuators, along with relays and solenoids as the primary items. ¹
• Excludes: Contactors and other electrical control equipment; classify those items under PSC 6110. ¹
• Group 59 note: Specially designed mounting hardware (e.g., brackets, holders, retainers) for Group 59 items may be included within Group 59 classes; general-purpose screws, bolts, studs, washers, rivets, and other common hardware are excluded and classified in Group 53. ¹

Reporting tips from official guidance

• In FPDS, the PSC is recorded in data element 8A at the CLIN level; applicable environmental attributes are recorded in element 8L. Select the PSC that reflects the predominant product on the action to ensure accurate reporting and analytics. ¹
• DFARS PGI guidance requires PSCs to be included for separately identifiable contract line items as part of the Uniform Contract Line Item Numbering System. Align CLIN structures so the PSC corresponds to the specific supply deliverables. ³

Frequently asked questions

• What is PSC 5945?

  • PSC 5945 is the product classification for Relays and Solenoids. The official entry includes electromagnetic actuators and directs use of this code when these items are the predominant deliverables on the contract action. It is part of Federal Supply Group 59 for electrical and electronic components. ¹

• How is PSC 5945 different from PSC 6110?

  • PSC 6110 covers electrical control equipment such as contactors, motor controllers, switchgear, and voltage regulators, and it explicitly excludes relays. Use PSC 5945 for relays, solenoids, and electromagnetic actuators; use 6110 for contactors and broader control assemblies. ¹

• Is PSC 5945 a product or a service code?

  • It is a product code listed in Section D (Product Codes) of the PSC Manual under Group 59, which encompasses electrical and electronic equipment components. Agencies should not use it to classify services or installation activities. ¹

• Are specific relay or solenoid subtypes (e.g., time-delay, latching) enumerated for 5945?

  • Not specified by official sources. The manual provides the class-level description and examples (relays, solenoids, electromagnetic actuators) without enumerating a detailed subtype list for 5945. Agencies should rely on the predominant-item rule when selecting the PSC. ²

• Where is PSC 5945 recorded in procurement systems?

  • Agencies record PSCs in FPDS at the CLIN level (element 8A). Environmental attributes, when relevant, are captured in element 8L. Ensure the CLIN structure and PSC align so reporting accurately reflects the supply deliverables. See also on G2X: PSC 5945. ¹
