Product Description:
Danaher manufactures the EA700-55000. The Danaher EA700-55000 Snaplock limit switch has 19.5 inch-pounds of actuation torque. Torque is the rotational force required to move the actuator through its switching sequence in electromechanical systems. This device has a high torque threshold to prevent false triggering from accidental contact, mechanical drift and ambient vibration. In high-load industrial automation applications where devices are exposed to dynamic pressure, this mechanical resistance is key. The switch supports system accuracy and integrity in complex electromechanical applications by requiring a lot of torque to change the contact state. This ensures consistent performance in tough operating conditions.
The angular displacement of the EA700-55000 provides better motion control and fine mechanical feedback. Although the recommended operating range is 45 degrees to prevent over-extension and internal mechanical stress, the actuator can sweep a large arc with its 90-degree travel. The trip and reset angular thresholds of 11 and 9 degrees, respectively, are set within this range. The internal calibration points mark the exact times of electrical state changes. In applications where time and position are critical, like synchronized manufacturing lines or robotic arm end effectors, this granularity allows for predictable behavior. By not having excessive or irregular actuation cycles, this angular precision not only improves the switch’s response but also its mechanical life.
The EA700-55000 can interface with power-dense components in industrial circuits as it can handle 20 amps continuous at 125V AC. The conductive path design and internal contact metallurgy are shown by its current carrying capacity, which allows for continuous power transfer without resistive loss, contact pitting, or thermal degradation over time. The word “continuous” means the switch is suitable for long-term load applications like load control panels, relay-driven solenoid actuators and motor starters. The enclosure meets NEMA Type 1, 4, and 13 requirements, meaning it’s resistant to dust, water intrusion, and noncorrosive contaminants and electrical durability. The switch can operate in various climatic conditions as it’s made of zinc-aluminum alloy and rated for -20°C to 90°C. Its rugged construction is further backed up by its 4-pound weight, which means it’s suitable for mission-critical industrial applications that require both electrical and mechanical durability.
