Snap action, limit switches are important components of automated processes where machines, robots and other systems need to detect the presence or absence of an object in a specific location. The GKLE40LXA2 is one of the most advanced and reliable of these switches.

Overview of the GKLE40LXA2

The GKLE40LXA2 is a subminiature snap action, limit switch designed for harsh and industrial environments. The device has a durable construction and comes with a long-life, dry reed contact rated for 1 million mechanical operations and 0.5 million electrical operations.

Measuring just 5.4mm wide x 4.4mm high x 19.6mm long, the device features gold-plated terminals, as well as an optional flood circuit for added protection from environmental influences. It is available in normally open, normally closed and changeover versions, with a choice of actuator direction and travel.

Application Fields

The GKLE40LXA2 is suitable for a wide range of applications, from medical equipment and office automation to industrial robots and power control systems. It is ideal for use in areas where a small, high-precision switch is needed, such as material-handling systems and in automated systems that require high levels of reliability.

It is also suitable for process automation, such as flow and level sensing, and for protecting motors and other high-voltage components from accidental overloads or reversing when energized. Additionally, it can be used in measuring systems, such as pressure, temperature, and fluids, and safety systems, such as lighting and construction zone detection.

Working Principle

The GKLE40LXA2 uses a snap action, a form of mechanical contact, which is activated when the lever is moved past its operating threshold. As the lever does so, it creates a sharp mechanical movement, which leads to an immediate change in the contact state from open to closed, or vice versa. This movement is then used to trigger an electrical signal, allowing the switch to control a variety of automated processes.

When the actuator is pushed, the lever of the switch rotates around an internal pivot, which is supported by a coil spring. As the lever is pulled, it again rotates until it triggers the contact mechanism. This same principle can be used to detect the presence (or absence) of objects in many automated systems.

The GKLE40LXA2 has been engineered with a snap action feature and is designed to meet the most stringent of safety requirements. It is also capable of operating in extreme temperatures, up to +70°C, so it can be used in a wide range of applications, including those in harsh industrial environments.

Conclusion

The GKLE40LXA2 is an advanced, rugged and reliable limit switch designed for industrial use. With a long-life, dry reed contact rated for 1 million mechanical and 0.5 million electrical operations, as well as a flood-proof construction, it is suitable for a variety of applications, including flow and level sensing, motor protection and areas where a small and precise switch is needed. The device uses a snap action mechanism which is activated when the lever moves past its operating threshold, triggering an immediate change in contact state.
