High-quality construction: durable plastic housing combined with metal components for a compact, long-lasting limit switch. Designed to be waterproof, dustproof and power resistant for reliable operation in demanding environments. Adjustable lever arm: freely change the length of the lever arm to match your required travel or actuation point. Simple mechanical adjustment lets you fine-tune travel without replacing parts. Rotatable actuator with automatic reset: the lever is rotatable and returns automatically after actuation. The device uses a double-spring mechanism and an integrated conversion mechanism to improve durability and extend service life. Versatile contact configuration: provides 2 normally closed (NC) and 2 normally open (NO) contacts to support multiple wiring options and control schemes. Electrical ratings: AC 250V, 5A / DC 115V, 0.4A. Please check the rated voltage and supply voltage at your site before purchase to ensure correct operation. Key benefits — why you need this limit switch Precise position detection: adjustable lever and clear NC/NO contacts let you set accurate end-of-travel or safety limits. Reduced downtime: robust materials and the double-spring automatic reset design provide longer life and fewer replacements. Flexible integration: compact size, rotatable actuator and multiple contacts make this switch easy to adapt into existing equipment and control systems. Typical applications Industrial machinery: end-of-travel detection on milling machines, presses or other automated equipment. Conveyor and material handling: position sensing and safety interlocks for conveyors, sorting lines and packaging machines. Door and gate systems or robotics: limit detection for garage doors, automated gates, pick-and-place robots and linear actuators.
