ALCO Switch ALCO 164TL

Core Features Reinforced Toggle Lever Design for High-Impact Use: Functions as a heavy-duty limit switch engineered to withstand rigorous industrial conditions, featuring a forged steel toggle lever (150mm length) with a 30mm hardened steel roller. This robust actuator handles repeated high-force contact with large moving components (e.g., steel machine slides, industrial door panels, or conveyor rollers) without deformation, making it ideal for mining, steel production, and heavy manufacturing. Positive Break Mechanism for Reliable Switching: Equipped with a positive break contact system that ensures contacts open/close with absolute certainty, even under vibration or partial actuation. This design eliminates "false safe" signals, critical for safety-critical applications like emergency stop circuits or overtravel protection. The switch features a double-pole double-throw (DPDT) configuration (2 NO + 2 NC), providing redundant contacts for enhanced system reliability. Broad Electrical Compatibility: Rated for AC 125V/250V/480V (50/60Hz) and DC 30V/60V, with a maximum switching current of 20A (resistive) and 10A (inductive). This range enables direct control of: Heavy-duty motors, pumps, or hydraulic valves in industrial machinery. Safety relays and interlock systems in high-risk equipment. High-power auxiliary systems (e.g., industrial lighting, ventilation fans). IP67/IP69K Protection for Extreme Conditions: Housed in a cast stainless steel housing (316 grade) with a hermetically sealed chamber, providing exceptional resistance to corrosion, high-pressure water, and chemical exposure. It meets IP67 (submersion to 1m) and IP69K (high-pressure, high-temperature washdown) ratings, suitable for food processing, offshore platforms, or environments with aggressive cleaning agents. Adjustable Actuation Parameters: The toggle lever offers 360° rotation and adjustable trip points, allowing customization to specific machine geometries. A heavy-duty return spring (12N force) ensures reliable reset even after repeated high-impact actuations, while the steel roller minimizes friction and wear on both the switch and target components. Global Safety Compliance: Meets IEC 60947-5-1, UL 508, and CSA C22.2 No. 14 standards, with additional certifications for hazardous locations (ATEX Zone 2). It operates in extreme temperatures ranging from -50°C to +120°C (-58°F to 248°F) and resists vibration (10–500Hz, 20G) and shock (150G peak), ensuring reliability in the harshest industrial settings. Typical Applications The ALCO Switch 164TL is engineered for heavy-duty position sensing in extreme environments, with core use cases including: Steel Mill Equipment: Installed on rolling mills, furnaces, or coil handling systems to detect workpiece positions or equipment travel limits. The stainless steel housing resists molten metal splatters and high ambient temperatures. Offshore/Marine Systems: Deployed on offshore platforms or ships to monitor valve positions, crane movements, or hatch closures. The corrosion-resistant 316 stainless steel housing withstands saltwater exposure and harsh weather. Food Processing Lines: Used in meatpacking, dairy, or beverage plants to monitor conveyor positions or door interlocks. The IP69K rating withstands high-pressure, high-temperature washdowns with caustic cleaners, complying with FDA and EHEDG standards. Mining Machinery: Integrated into mining equipment (e.g., crushers, conveyor belts, or drilling rigs) to detect jams, overtravel, or component misalignment. The rugged design resists dust, vibration, and impact from rock debris. Wastewater Treatment: Installed in wastewater plants to monitor gate positions, pump strokes, or filter status. The corrosion-resistant housing withstands exposure to chemicals and moisture.
