Limit Switch LX4 - Reliable Travel Control Mechanism from China Suppliers and Factory

,

The LX4 limit switch is designed for use with AC 50~60Hz; AC380V; DC220V control circuits with a current capacity of 20A. This essential component is ideal for operating and limiting the travel of various mechanical systems. Each type of limit switch in the LX4 series is tailored for specific application conditions based on its unique structure. For instance, the LX4-11 and LX4-12 limit switches are particularly suitable for translation mechanisms with small inertia travel.

,

On the other hand, the LX4-21 and LX4-22 limit switches excel in situations requiring large inertial travel. For lifting mechanisms, the LX4-31 and LX4-32 limit switches are the preferred choices. Furthermore, the LX4-12S limit switch is specially crafted for translation mechanisms with large inertial travel in environments that demand waterproofing.

,

These limit switches are designed to operate in conditions with an altitude of no more than 1000 meters, ambient temperatures ranging from -30℃ to +40℃, and a relative humidity not exceeding 85%. They also boast a protection level of IP44, in compliance with the GB/T14048.5-2017 standard.

,

As a leading product from China, the LX4 limit switch is vital for controlling the travel of mechanical equipment and ensuring limit protection. Commonly known as a travel limit switch, it is strategically installed at designated positions on mechanical equipment. When moving parts engage the limit switch, the contact mechanism triggers to switch the circuit, thereby controlling the travel of mechanical systems and providing essential limit protection. Trust China suppliers and factories for reliable and high-quality LX4 limit switches to enhance the efficiency and safety of your operations.
