MICROTHERM T11A Thermal Switch, NC, 150°C

The MICROTHERM T11A Thermal Switch is a high-performance, temperature-sensitive safety device featuring a normally closed (NC) contact. Designed for reliability and silence, it offers a high power rating and operates with no vibration noise, making it ideal for precision applications. Its construction is tightly sealed against ordinary resins and lacquers, ensuring excellent resistance to impregnation during manufacturing processes.

This switch is engineered to automatically open the circuit when the ambient temperature reaches its calibrated switching point of 150°C, providing critical thermal protection. With its compact dimensions (33mm x 22mm x 2mm) and lightweight build, it is perfectly suited for integration into space-constrained assemblies. The sensor features practical wire leads for straightforward electrical connection.
