5003 | SERIES
1/2” BIMETAL DISC THERMOSTAT
Introduction
The 5003 series is a RoHS compliant, positive snap action, single pole / single throw, bimetallic thermostat which provides accurate
and reliable sensing and switching in a single device. It is ideal for applications when space is at a premium with overall depth, without
projecting terminals, being only 0.250 in.
The basic switch assembly is operated by a bimetal disc with positive, reinforced snap-action, which is known for its reliable repeatability.
With several terminal and mounting options, the 5003 series offers excellent shock and vibration resistance due to the robust construction
of its switch assembly. For high humidity and contaminating atmosphere applications, the device is sealed with a non-volatile resin.
Narrow differential devices are ideal for control, while standard differentials can be used for high or low temperature limit switches.

Note
• Select any temperature in the range of 35°F to 325°F. Standard choices fall on the 5°F increments, for example 140°F, 145°F, 150°F, 155° F... up to 320°F or 325°F
• Specify the °F temperature in the part numbering scheme as a three digit code without the ‘°F’ in the part numbe r. For example, for 200°F, put in code ‘200’
• Bottom Temperature in °F” equals the “Top Temperature in °F” minus “Nominal Differential in °F”. For example 310°F - 30°F = 280°F

Note
• The standard tolerance for the top temperature is based on the temperature range the top temperature falls in, please refer to the temperature setting chart, and
select the appropriate code for a standard top temperature tolerance
• For bottom temperature tolerance a “Y” = minimum trip, which indicates the “reset” trip occurs at or above the lower temperature set point.
