Global PTC Heater and Hall Effect Sensor Markets Projected to Grow Through 2032

LP Information’s market research projects the worldwide PTC heater market to reach roughly US$3.3 billion by 2032, growing at an average annual rate of 6.9% from 2026. Demand is driven primarily by electric‑vehicle thermal management, with the sector accounting for over 60% of projected sales. Major manufacturers such as MAHLE and Webasto are expanding high‑voltage, modular heater solutions for vehicle cabins, batteries and coolant pre‑heating.

The firm also forecasts the global Hall‑effect sensor market to expand to about US$3.5 billion by 2032, at a 5.1% CAGR. Growth is fueled by the same electric‑vehicle boom, as sensors are used for motor position detection, current measurement and safety functions. Leading players include Allegro MicroSystems, Infineon, TDK, and Chinese firms expanding into automotive applications. Both reports highlight the broader shift toward high‑performance, integrated components in the fast‑growing electric‑vehicle and smart‑manufacturing sectors.
