| EXTREME TEMPERATURE SERIES (M24236/2)

Extreme Temperature Protection Probe–Type Thermal Switches

Introduction

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.
