Klixon® 11041 (M1) extreme temperature probes are designed to provide reliable, consistent performance over a long cycle life in the harshest environments. These probes provide excellent shock and vibration resistance and have a wide operating temperature range or -65°F to +550°F. These characteristics enable protection or indication of extreme high or low temperatures in systems like aircraft hydraulic systems, aircraft refrigeration systems, constant speed drives, food processing equipment, and hydraulic systems for military equipment.
