Snap action, limit switches are widely used in various industrial automation and process control applications. The main characteristics of a limit switch are its reliable operation, high repeatability and its low cost. The most popular type of limit switch is the standard type, which is suitable for most applications. However, in certain applications, the requirements are more complex, and the use of an alternate type is necessary. One such type is the LSD7L limit switch.

LSD7L Application Field:

The LSD7L is a precision, two-stage actuated limit switch designed for operations involving harsh environments, higher frequency actuation, and long-term reliability. The LSD7L is perfect for applications including moving parts, and is used in the automotive industry for door, hood, and trunk lid open/close detection, in machine tools for detecting the position of machine slides, and in robotics for precision sensing of actuators. It is also ideal for hazardous areas where long-term use in explosive environments is required.

LSD7L Working Principle:

The LSD7L is a two-stage limit switch, consisting of two microswitches which are in a series. The first microswitch, called the inactive switch, is the one which will be momentarily actuated when the plunger of the limit switch is contacted by the activating part. The second microswitch, the active switch, is the one which will be always actuated when the plunger is in its activated state. This provides a more reliable operation as well as higher precision.

When the two-stage limit switch is actuated, the active switch will be activated first, followed by the inactive switch. This is done by the plunger being pushed forwards by the activating part, until it eventually reaches the end set by the user. This in turn will cause the inactive switch to be activated, and the active switch to remain activated until the plunger is released. This ensures repeatable and long-term operations, and is perfect for applications requiring higher levels of precision and reliability.

Another advantage of the LSD7L limit switch is its ability to operate in multiple directions. This means that the same switch can be used for operations in different directions, allowing for greater flexibility and increased reliability. This makes it ideal for applications with multiple levels of operation, such as robotics and machine tools.

The LSD7L is also highly resistant to electrical and mechanical wear, making it ideal for long-term applications. Additionally, the LSD7L features a sealed plunger, which helps prevent moisture and dust from entering the switch, increasing its reliability and service life.

By using the LSD7L, users can benefit from reliable and inexpensive solutions that can be used in a variety of applications. With its two-stage actuation and its ability to operate in multiple directions, the LSD7L can provide reliable operation, improved safety, and increased efficiency.
