The cross limit switch from Yueqing Huilong Industrial Control Electrical Co., Ltd. is a precision - engineered safety device designed to prevent over - travel in industrial machinery by detecting when a moving component crosses a pre - defined boundary. Constructed with a rugged aluminum alloy housing, this switch withstands harsh environments, featuring IP67 waterproof and dustproof ratings. Its internal microswitch mechanism ensures rapid response times within 5ms, while the adjustable triggering distance (10 - 50mm) allows customization for diverse applications. The switch incorporates a double - layer contact design with silver - alloy terminals, enhancing electrical conductivity and extending service life to over 1 million operations. Ideal for conveyor systems, robotic arms, and CNC machines, it integrates seamlessly with PLC control systems, providing real - time position feedback and emergency stop functions. The cross limit switch undergoes rigorous testing, including 1000V dielectric withstand and 50G vibration resistance, ensuring reliability in heavy - duty manufacturing environments.
