Description
Description
Description: Cat components make certain that your equipment is operating at an optimal level. Cat temperature switch assemblies are actuated when the temperature range exceeds the limits in Cat engine components.
Attributes: • Temperature switch with screw terminals • Brass body and tube • Actuation Temperature: 129° C (264° F) • Operating Temperature: -40° to 150° C (-40° to 302° F) • Contact Position: Normally closed below deactuation temperature • Voltage: 8-28 VDC • Medium: Oil, fuel, air and coolant • Impervious to oil, fuel, water, dust, salt, glycol and engine cleaners • Connector Type: 2-screw terminal • Hex Size: 17.45 mm (0.687 in) • Thread Size: 3/8-18 NPTF • Accurate temperature sensing • Designed to work in unison with the rest of your Cat components to ensure maximum potential of your equipment
Application: Used in engines of Cat vehicles. Consult your owner's manual or contact your local Cat Dealer for more information. Cat components can operate in heavy-duty applications such as severe vibration, shock, extreme operating temperature ranges, thermal cycle, thermal shock, humidity, corrosion and excessive dust.
