TMC Sensortechnik

What TMC Sensortechnik does

TMC Sensortechnik GmbH is a privately held German manufacturer of thermal protection solutions for electric windings, founded in 1995 and headquartered in Bretten, Germany. The company designs and produces miniaturized bimetal switches (Series C, R, F, and H), platinum and PTC/NTC temperature sensors (Series S, M, and the wire-free MR "Rocket" series), positioning technologies (PI-Sensor, Latching Aid), and an integrated Click & Play system that enables fully automated assembly of motor protection components. Products are specified into electric motors, transformers, generators, charging infrastructure, industrial lasers, batteries, and fuel cells, with named end-users spanning drive and control (Bosch Rexroth, SEW-Eurodrive, Schunk), HVAC and pumps (EBM-Papst, Ziehl-Abegg, Wilo, Rosenberg), industrial lasers (Trumpf, Nvidia for AI chip manufacturing), EV charging (Juice Technology), and automotive (MAHLE).

The company operates two production sites — Bretten (Germany) and Police nad Metují (Czech Republic, opened June 2023) — and runs a vertically integrated value chain through its 2022-founded sister company BGF Enztech GmbH in Pforzheim, which supplies precision metal stamping and high-performance plastic injection molding for positioning components and the Click & Play system. The business model is hardware sales with project-based, quote-driven pricing, direct-to-customer distribution through a 4-person sales and consulting team, and revenue is generated from individual components, pre-assembled sensor chains, and complete systems. The company has produced more than 200 million temperature monitors since 1995, serves over 200 active customers from more than 20 nationalities across its ~80-person workforce, and holds over 20 active patent families with global certifications (VDE, TÜV, KEMA, UL/ETL, CQC, CRUUS, DEKRA, INTERTEK) plus ISO 9001 and ISO 14001.

Core offering

TMC Sensortechnik GmbH designs, manufactures, and sells thermal protection components and systems for electric windings. Its portfolio includes miniaturized, self-holding, and flat bimetal switches (Series C, R, F, H), platinum and PTC/NTC temperature sensors (Series S, M, MR), positioning technologies (PI-Sensor, Latching Aid), and fully integrated Click & Play wire-free sensor systems for automated motor assembly. These products protect electric motors, transformers, generators, charging infrastructure, lasers, batteries, and fuel cells from overheating in industrial, automotive, HVAC, and e-mobility applications.

Product overview

TMC Sensortechnik is a German manufacturer of thermal protection solutions consisting of temperature sensors and bimetal switches. The product portfolio centers on three main categories: (1) Sensors including Pt1000/Pt100 platinum elements (Series S), PTC ceramic sensors (Series M), and cable-free MR Rocket sensors; (2) Bimetal switches in Series C (miniaturized), R (self-holding), F (world's flattest at 2.3mm), and H (high-performance up to 12A); and (3) Positioning technologies including PI-Sensor and Latching Aid for precise sensor placement. The Click & Play system integrates these components into complete wire-free solutions with automated assembly capabilities. Products protect electric motors, transformers, charging infrastructure, lasers, and batteries from overheating across industrial applications.
