Snap action, limit switches are tools used in automation applications in order to detect a parameter or to measure a certain condition. The 311SM717-T is a type of limit switch designed for high accuracy positioning, providing speed control for the device or the mechanism. This device offers excellent repeatability, with a repeatability accuracy of +/- 0.02 millimeters per revolution. It is also one of the most reliable limit switches available in the market. It is available in two-wire and three-wire configurations.

The 311SM717-T utilizes a progressive contact system, where each contact is operated independently. This design results in greater accuracy and repeatability, and also ensures that the contacts remain at the highest level of reliability. In addition, the switch contains a self-aligning switching element with adjustable force-closed operation for greater stability. This ensures that the switch remains at the highest level of accuracy even over time.

The 311SM717-T is designed for a wide range of automation applications such as industrial control, process control, and robotic control. It is also suitable for applications in the automotive, aerospace, or medical industries. Additionally, it can be used for applications in hazardous areas, since it is rated to UL 508C standard. This rating ensures that the switch is safe to use in these hazardous environments.

The working principle of the 311SM717-T is based on its progressive contact system. When the switch is moved, a switching plunger is engaged, which activates the contacts. The contacts move in relation to the motion of the switch and the plunger, creating an electrical signal. As the switch is moved further, the contacts move until they reach the desired settings and the electrical signal is triggered. This signal can then be used to control the device or the mechanisms connected to it.

The 311SM717-T is also designed for durability and reliability. It is rated to an IP67 ingress protection rating, making it suitable for operation in harsh and hazardous environments. Additionally, it is constructed from corrosion resistant aluminum alloy and stainless steel components. This ensures that the switch remains at the highest level of reliability and accuracy even after long-term use.

The 311SM717-T is an extremely versatile and reliable limit switch designed for a wide range of industrial applications. Its progressive contact system, self-aligning switching element, and adjustable force-closed operation provide excellent accuracy and repeatability. This, combined with its durability and IP67 rating makes it an ideal choice for many automation applications, including hazardous environment applications.
