Industrial ER5018-021N Rope Pull Emergency Stop Switch

Omron's ER5018-021N Compact Rope Pull Emergency Stop Switch is a rugged remote-stop device for conveyors and other automated equipment, designed to halt machinery quickly through a pull cord. It fits a 40 mm mounting width, uses a die-cast enclosure with IP67 (NEMA 6) protection, and includes a stainless steel eye nut for durability in washdown or harsh environments. The unit employs a 3PST (three-pole, single-throw) contact arrangement with typical ratings around 6 A at 120 V and supports rope spans up to 40 m, aided by a tension indicator that helps installers set and verify proper rope tension while remaining vibration tolerant. An integrated blue reset button must be pressed to restore operation after actuation, ensuring a deliberate restart, and the device is commonly deployed on conveyors, packaging lines, and around hazardous areas where a remote emergency stop along the rope path is required.
