EA170-52100 by Danaher

The Danaher EA170-52100 is a robust limit switch from the Snaplock Limit Switches series, engineered for precision in industrial automation and safety interlocks. It features an IP55 protection rating to guard against dust and water spray, and operates on an operating voltage of 110-240 VAC at 50/60 Hz. Weighing 7.5 kg, this flange-mounted switch offers a durable cast aluminum enclosure and stainless steel components for reliable performance in demanding environments. Designed for applications such as motion detection systems, emergency shutdown circuits, and machine guarding, it provides accurate actuation and dependable repeatability.

This model employs a forced air cooling method and delivers a power rating of 500 W at an efficiency of 92%, ensuring stable thermal management under continuous operation. The stainless steel actuator lever can be adjusted in 7.5° increments up to 173° total travel, with a recommended actuation angle of 13° for precise switching action. The flange mount design simplifies installation and alignment, while the use of 8-32 SEMS screws streamlines wiring connections. The reverse shaft configuration offers flexible mounting orientations, and the heavy-duty internal latching mechanism holds the lever securely once actuated, preventing unintended resets in high-vibration settings.

Built to withstand temperatures from 0°C to 50°C and rated for currents up to 20 A at voltages ranging from 125 V to 600 V AC, the EA170-52100 meets rigorous industrial standards including IEEE 344-1975, IEEE 323-1974, and IEEE 382-1972 for seismic qualification and nuclear environment readiness outside containment areas. Its IP55-rated cast aluminum housing and stainless steel construction provide exceptional resistance to environmental hazards, while the forced air cooling system maintains optimal internal temperatures for long-term durability. Ideal for process control, conveyors, and safety interlock panels, this switch enhances operational reliability and extends maintenance intervals, making it an invaluable component in modern automated systems.
