1/2″ Automatic Reset Snap Disc Thermostats

Senasys tests our snap disc thermostats through air, fluid, hot plate and other testing standards. Learn more about our quality inspection here.

For small quantities, we can build anything from 0°F to 350°F. Contact us for higher temperatures.

For these types of switches 10ºF is about the smallest range they can maintain cost effectively and consistently.

For complex systems actual testing is usually pretty important. We support this process by making it easy to test multiple package styles and disc temps in sequence or all at once just give us a call. Learn more about temperature differentials here.

Yes! Senasys can cross reference most Thermodisc and other manufacturers on the market today with our extensive catalog. Send us more details such as drawing, part number and/or description for quote.

We have the ability to produce most metal component parts in house, and have an extensive supplier catalog that allows us to meet most application requirements. Contact us with your specifications.

One of the standout characteristics of an exposed cap is its’ use of a black exposed disc. This disc serves as a crucial element in sensing temperature fluctuations swiftly, enabling the switch to respond rapidly to environmental changes. This quick thermal response is especially important in applications where precise temperature control is paramount, such as in thermostats, industrial control systems, and appliances. The exposed caps are available for all non-epoxied snap disc thermostats within the Senasys catalog.

One of the key advantages of gold contacts is their significantly lower contact resistance when compared to high-current silver contacts. This low resistance translates into improved electrical conductivity, allowing for smoother and more reliable signal transmission. This is especially important in applications where even the slightest interruption or distortion in the signal could lead to critical errors or malfunctions.

When it comes to temperature monitoring, precision is key. The standard flange mount plays a vital role in achieving this precision by minimizing the distance between the sensor and the area being measured. This reduced gap ensures that temperature fluctuations are detected and recorded with remarkable accuracy, making it an indispensable tool in industries where temperature control is critical.

Continuity! Whether you have a hot or cold temperature thermostat, this test is easy and one of the first things we ask customers. Learn how to do so here.

Our standard tolerance is between 5°F to 10°F, but tighter tolerance options are available. We also offer a min/max type. Click here to learn more, or contact us with your requirements.

The location of the temperature switch inside your heating element should be well thought through. Temperature will change in various locations within the system depending on the heating element location. The further you distance from the heating element, the lower the temperature. Where a temperature switch is located will determine how accurate it can measure and control the system. Senasys typically recommends with all of our temperature switches the closer you can get to the heating element the better for the most accurate reading and fastest response time.
