Yueqing Huilong’s roller limit switch is designed for applications requiring direct mechanical interaction with moving parts. The switch features a heavy - duty rubber - coated roller (diameter 50mm) that withstands 300N of impact force, ideal for detecting large machinery movements. Its die - cast aluminum housing (with powder coating) resists corrosion, while the internal microswitch (10A/250V AC) offers long electrical life. The roller arm can be adjusted through 180°, allowing flexible positioning for optimal triggering. With an IP65 protection rating, it performs in dusty or wet environments, commonly used in woodworking machines, textile equipment, and material handling systems. The switch also includes a shock - absorbing mechanism, reducing noise and vibration during operation, enhancing workplace safety.
