• Fast time response for surface applications
compared to industry standard NTC lug sensors
Available
• Reduced thermal gradient, due to the use of
small dimensions and nickel conductor,
allowing for an accurate surface temperature
measurement
• The sensor is not suitable for being permanently
in contact with water or liquids
• Small size connector and small lug ring tongue terminal,
allowing for temperature sensing at locations where only
limited space is available
• Optional connector, rated +85 °C, tin plated (e3)
• AEC-Q200 qualified available (grade 1)
• cULus recognized, file E148885
(UL category XGPU2/XGPU8)
• Material categorization: for definitions of compliance
