China LX4 Limit Switches - Reliable Suppliers & Factory for AC/DC Control Circuits and Mechanical Travel Limit Protection

, The LX4 limit switch is a highly versatile device designed for effective travel control in various mechanical systems. Operating seamlessly within AC 50~60Hz; AC380V; and DC220V environments with a current capacity of 20A, this limit switch is ideal for both translation and lifting mechanisms. As a leading product from reputable China suppliers, the LX4 series caters to specific applications: LX4-11 and LX4-12 are perfect for translation mechanisms with small inertia, while LX4-21 and LX4-22 are tailored for those with larger inertial travel. For lifting applications, LX4-31 and LX4-32 limit switches excel, ensuring precise movement control.

,

, Significantly, the LX4-12S model offers enhanced waterproof capabilities, making it suitable for translation mechanisms where moisture protection is critical. All LX4 limit switches function optimally at altitudes not exceeding 1000m and within a temperature range of -30℃ to +40℃, with a relative humidity level below 85%. They also adhere to the rigorous GB/T14048.5-2017 standard and feature an IP44 protection rating.

,

, These limit switches are essential components in controlling mechanical equipment travel and providing vital limit protection. Installed at predetermined locations on machinery, they activate when moving parts encounter limits, thereby switching the circuit and managing equipment mobility. Trustworthy and efficient, the LX4 limit switch is a must-have for factories seeking reliable travel control solutions. Choose our products from trusted China suppliers to ensure quality and performance for your mechanical applications.
