What SSI Control Technologies does
SSI Technologies, LLC (doing business as SSI Control Technologies) is a privately held sensor and gauge manufacturer founded in 1982 and headquartered in Janesville, Wisconsin. The company designs, develops, and manufactures three primary product families: ultrasonic liquid level sensors, piezoresistive pressure sensors, and magnetic speed/position sensors (using Variable Reluctance, Hall Effect, and Magneto-Resistive technologies), complemented by digital gauges, DEF/Urea heater modules, and integrated tank systems. Its proprietary technology includes custom ASICs for signal conditioning and temperature compensation, and combination sensors (notably the TULC sensor for SCR Diesel Exhaust Fluid applications) that consolidate multiple measurement functions into a single device.
The company operates exclusively in a B2B enterprise field sales motion, targeting large OEM customers with high-volume production contracts — minimum order quantities for speed and position sensors start at 100,000 units — while reaching mid-market and lower-volume buyers through a network of 12+ authorized distribution partners including Allied Electronics, Arrow, Avnet, Digi-Key, Mouser, TTI, and exclusive distributors Kodiak Controls and Heilind Electronics. Revenue is generated primarily through hardware sales of physical sensor products, with custom sensor development and manufacturing services for automotive and industrial OEMs representing a significant incremental revenue stream. SSI holds IATF 16949 automotive quality certification and reports cumulative deliveries of more than 100 million sensor units to automotive OEM customers.
SSI operates across five countries with wholly-owned subsidiaries in the United States (Wisconsin headquarters and Michigan technical center), Germany (European sales), Czech Republic (manufacturing facility opened 2015 in Přestanov with ~250 planned employees and over $24 million in technology investment), and China (Amphenol Changzhou Connector Systems). The company serves six vertical markets — automotive OEM, heavy truck and commercial vehicle, mass transit, motorcycle, material handling, and HVAC/industrial — with automotive OEM and heavy truck as primary segments driven by emissions compliance mandates for DEF/Urea sensing.
