ALCO Switch ALCO TE3-S1

Core Features Heavy-Duty Roller Lever for Versatile Sensing: Functions as a robust limit switch with a reinforced steel roller lever (100mm length) and 20mm nylon roller, engineered for reliable position detection in medium-duty industrial applications. The lever’s 360° rotatable design allows flexible alignment with moving components (e.g., conveyor belts, machine slides, or door panels), making it suitable for diverse machinery in manufacturing, logistics, and material handling. Snap-Action Contacts for Consistent Switching: Equipped with a positive snap-action mechanism that ensures instantaneous contact opening/closing (≤8ms response time), minimizing contact bounce and preventing false signals in control circuits. The switch features a single-pole double-throw (SPDT) configuration (1 NO + 1 NC), supporting integration into both primary control systems and auxiliary monitoring circuits. Broad Electrical Compatibility: Rated for AC 125V/250V (50/60Hz) and DC 30V, with a maximum switching current of 10A (resistive) and 2A (inductive). This range enables direct control of: Medium-power devices (e.g., small motors, solenoid valves, or indicator lights). PLC input modules (e.g., Allen-Bradley Micro800, Siemens S7-1200) for automated process monitoring. Alarm systems in industrial safety circuits. Durable Housing with IP65 Protection: Housed in a die-cast zinc alloy housing with a corrosion-resistant plating, providing durability in harsh environments. It meets IP65 protection (IEC 60529)—dust-tight and water-jet resistant—suitable for exposed installations on factory floors, outdoor equipment, or washdown areas (e.g., food processing facilities). Adjustable Actuation Parameters: The lever arm features a tool-free rotation and adjustable trip point, allowing customization to specific machine geometries. A reliable return spring (6N force) ensures consistent reset after actuation, while the nylon roller reduces friction and wear on both the switch and target components. Simplified Installation & Wiring: Designed for surface mounting via two M4 screws, with a compact footprint (55mm × 40mm × 30mm) that fits in dense control setups. The rear terminal block uses screw-type connections with captive washers, accepting 0.5–2.5mm² solid/stranded wires for vibration-resistant wiring. Clear labeling (NO/NC/Common) prevents wiring errors. Typical Applications The ALCO Switch TE3-S1 is engineered for versatile position sensing in medium-duty industrial systems, with core use cases including: Conveyor Systems: Installed along material handling lines to detect product presence, belt alignment, or end-of-travel positions, triggering stops or diverters to prevent jams. Industrial Door Control: Used to monitor the open/closed status of warehouse doors, loading bay gates, or machine enclosures, ensuring safe operation and preventing collisions. Packaging Machinery: Deployed in filling, sealing, or labeling machines to verify container positioning, ensuring accurate processing and reducing product waste. Material Handling Equipment: Integrated into forklifts, palletizers, or automated guided vehicles (AGVs) to detect load positions or travel limits, enhancing operational safety. HVAC Systems: Installed in large industrial air handlers or damper controls to monitor component positions, ensuring efficient airflow and temperature regulation.
