The OHD1-105M is a mechanical thermostat that functions as a temperature sensor for applications such as controls, automation, residential-commercial HVAC, and industry. It contains a bimetallic element that changes shape in response to temperature. This change of shape opens or closes a pair of contacts, allowing current to pass depending on the current temperature.

The OHD1-105M can be used in several different applications. One example of this is as a control for lighting systems. The OHD1-105M can be used to sense the ambient temperature and activate designated lighting accordingly. For instance, if the temperature in a room exceeds a certain level, the thermostat can turn on the air conditioning or lights, as necessary. Additionally, the thermostat can be utilized as a temperature limiter in certain products such as heated blankets, water heaters, refrigerators, and air conditioners.

The OHD1-105M also has multiple features that are designed to make the temperature sensor even more effective in its application. One of these features is its adjustable switch position, which allows the user to set the desired temperature limit and, in turn, determine when the switch will be opened or closed. This feature is especially beneficial in HVAC systems, as it gives the user more precise control over the temperature.

The design of the OHD1-105M makes it very reliable in its intended application. It is constructed with a bimetallic element, which is composed of two different metal alloys bonded together. When the temperature changes, the two alloys respond at different rates, resulting in the metal expanding or contracting. This expansion or contraction is then converted into an action that accesses the contacts, allowing current to pass or not pass depending on the current temperature.

The OHD1-105M is an excellent choice for control applications. It is inherently reliable, as it contains no electronic or digital components. This makes it much more resistant to failure, and it provides the user with the assurance of a long working life. Furthermore, its adjustable switch position feature allows for more precise temperature control, which is beneficial for a wide range of applications.
