What Microtherm does
Microtherm Sentronic GmbH is a German-based manufacturer of thermal measurement, protection, and control sensors, founded in 1965 and headquartered in Pforzheim, Germany. The company operates as a wholly-owned subsidiary of the Prettl Group following the 2020 transfer of Microtherm GmbH's business operations and global production companies. Its product portfolio centers on three categories: temperature switches (bimetallic snap-disc thermostats with high precision and narrow tolerances), temperature sensors (PTC, NTC, STS, and PT1000 thermistor-based devices with PT-series ranging from -40 to 180°C), and temperature fuses (one-shot thermal cutoffs rated up to 25A and 240°C). It also produces contactless Hall-effect position and angle sensors primarily for automotive air-flap management and has expanded into miniaturized F-series mini-switches and a flexible mini-sensor platform compatible with 0603 chips for confined-space installations such as stator slots in small electric motors.
Microtherm serves five primary end markets: automotive (IATF 16949-certified series supplier to international vehicle brands and Tier-1s for motion and temperature sensing), e-mobility/New Mobility (sensors for EV drive motors, charging plugs, and battery systems), industrial motors and heaters (overheating protection for pumps, compressors, transformers, and automation hardware), sensoric/general industrial and household (protection for appliances, HVAC fire dampers, and medical equipment), and renewable energy/medical technology (precision thermal management for photovoltaic, wind, and laboratory devices). The company runs four production sites in Germany, Czech Republic, China, and India, plus sales offices in Italy, Brazil, the USA, and Canada (Cantherm), and holds DIN-ISO, IATF 16949, VDE, UL, CSA, CCC, ENEC, and RCM certifications across all production facilities.
The revenue model combines direct enterprise field sales to large customers with multi-year supply contracts, a proprietary online shop (temperaturschalter-24h.de) with a €750 minimum order value for small-quantity buyers, and two distribution channels — Bürklin for the German mid-market (€750 minimum) and Mouser Electronics globally (no minimum) for NPI-driven volume. Revenue streams include standardized hardware sales, customer-specific sensor development from feasibility study through series production, and professional development services supporting 2D/3D design verification. The company reports over 250 employees and revenue exceeding €20 million, and is participating in the cross-company sens2act technology cluster established by Prettl Holding in 2025 to market integrated intelligent sensor solutions for electric drive applications.
