Allen-Bradley OP-AR1611 Splash Proof Limit Switch

The MICRO SWITCH OP-AR1611 Splash Proof Switch is a heavy‑duty electromechanical limit switch designed to detect position, presence, or end‑of‑travel in industrial control systems. Its splash‑proof, die‑cast metal housing supports panel or machine mounting and is built for industrial indoor and wet environments, making it suitable for conveyors, packaging machines, machine tools, and other factory automation equipment exposed to moisture, coolant, oil mist, or washdown conditions. Key specifications include a rated voltage of 480 VAC or 250 VDC, a motor rating of 1/8 HP, and a current rating of 1/2 A, with SPDT or DPDT contact configurations (configuration dependent). The actuator options include roller lever or plunger (application dependent), and electrical connections are via screw terminals. The part is manufactured by MICRO SWITCH (Honeywell) with the MPN OP-AR1611. Common replacements include the Honeywell MICRO SWITCH BZE6-2RN and LS Series splash‑proof switches, reflecting its role as a retrofit or upgrade in automation control systems.
