Joslyn Clark Controls

What Joslyn Clark Controls does

Joslyn Clark Controls is a product brand of Specialty Product Technologies (SPT, legal entity Dynapar Corporation), itself a subsidiary of Fortive Corporation, headquartered in Elizabethtown, North Carolina. The brand designs and manufactures vacuum contactors, starters, and motor controllers used to start and control electric motors in extreme industrial environments, including oil and gas operations, mining, cement production, utilities, water pumping, and mills. Products are positioned as mission-critical components where equipment failure is unacceptable, and the brand traces its heritage to the 1920s.

The company operates within a portfolio of six SPT brands (alongside Eagle Signal, Veeder-Root, Namco Controls, Superior Electric, and Thomson Nyliner) and sells primarily through SPT's direct global sales and support network into the industrial automation marketplace. Revenue is generated through product sales of electromechanical vacuum contactor hardware and motor starting solutions; no pricing model or software/recurring revenue layer is disclosed. The brand does not maintain its own standalone corporate site, presenting instead through the parent SPT platform at specialtyproducttechnologies.com/joslyn-clark.

Joslyn Clark is owned by Fortive Corporation, a diversified industrial conglomerate, after passing through the Danaher portfolio in 1986 and transitioning to Fortive when Fortive spun off from Danaher. Headcount across SPT is reported in the 251–500 employee band, and the brand operates with no disclosed product AI/ML or software component, functioning as a pure-play industrial hardware supplier.
