EA700-55000 by Danaher

The Danaher EA700-55000 from the Snaplock Limit Switches series by Danaher delivers reliable mechanical performance with a robust 19.5 inch-lbs actuation torque and a continuous current rating of 20A at 125VAC. This limit switch provides a total travel angle of 90° and a recommended operating travel of 45° to ensure precise actuation while protecting internal components from over-extension. Its primary application is in industrial automation systems where consistent, vibration-resistant switching is required for conveyor controls, motor starters, and safety interlocks.

In-depth technical specifications include a trip travel angle of 11° and a reset travel angle of 9°, giving fine mechanical feedback for synchronized operations. The device operates in a clockwise Direction Of Operation (CW) and uses a NP-4NO-CW-Solenoid3C-N-W switch configuration for four normally open contacts, ideal for redundant or multi-circuit designs. The housing is constructed from durable Zinc/Aluminum alloy, safeguarding internal contacts from mechanical wear and environmental stress. Mounting options include the standard EA700-25000 and wide EA700-55000 brackets, ensuring compatibility with various panel layouts.

Built for demanding environments, the EA700-55000 supports NEMA Type 1, 4, 13 enclosure ratings, offering dust, water spray, and non-corrosive contaminant protection. It operates reliably across a temperature range of -20°C to +90°C and weighs approximately 4 lbs, highlighting its sturdy design without excessive mass. Continuous current capability and specialized contact metallurgy minimize contact pitting and thermal degradation over prolonged duty cycles. By combining precision actuation angles, high torque thresholds, and versatile mounting, this limit switch enhances machine safety, accuracy, and uptime across industrial automation applications.
