Snap action, limit switches are electrical devices used in manual or automated control systems to indicate a physical limit to a range of motion. In industrial applications, a limit switch is used to detect the motion of a machine part, machine tool or electrical device. 25EN59-6 is an example of this type of limit switch and this article outlines the application fields and working principle of this device.

25EN59-6 is a heavy-duty limit switch suitable for outdoor environments. It has an EN60947-5-5 standard type 16A contact system and is available with a 2NC/2NO contact specification. The device has a long travel complete with end stops, making it suitable for applications where a large distance must be detected. This makes 25EN59-6 suitable for controlling the movement of large industrial machinery or other large devices. The time required to complete a full movement is around 16 milliseconds and this makes 25EN59-6 ideal for applications where fast responses are required.

The 25EN59-6 works using the lever principle. The device consists of a lever connected to an electrical sensor, which is operated by a mechanical spring-loaded mechanism. The lever is connected to a lever shaft, which moves when the lever is actuated. This motion is then detected by the sensor which in turn activates a switch that opens or closes, depending on whether the lever has hit the end stop or not. The lever shaft can be adjusted to detect different levels of motion and the sensitivity of the lever can also be adjusted depending on the application.

25EN59-6 is suitable for controlling a wide variety of applications including conveyor belt systems, press brakes, lathes and welding systems. The device can also be used to detect the presence of objects or to monitor the movement of heavy machinery. The versatility of 25EN59-6 makes it an ideal device for many industrial applications.

The working principle of 25EN59-6 is relatively simple but effective. When the lever is actuated, the lever shaft will rotate, causing the sensor to detect the movement of the lever. The sensor then triggers the switch and this will either open or close the contacts, depending on whether the lever fell within the predefined limits or not. The sensitivity of the device can be adjusted by increasing the spring tension of the lever mechanism, allowing the device to be used to detect small and large amounts of motion.

In summary, 25EN59-6 is an effective and reliable limit switch suitable for many applications. The device is well suited to controlling large machinery and other industrial applications. The working principle of 25EN59-6 is relatively simple, making it suitable for use in a variety of environments. The versatility of the device makes it an ideal choice for many applications requiring the detection of physical limits.
