Product Description:

The EA700-80001 is a limit switch which is designed and manufactured by Danaher. Categorized under the series of Snaplock Limit Switches it is well suited for industrial automation environments where precise actuation, high forces and robust electrical contacts are required.

The EA700-80001 limit switch needs 27 in-lbs amount of torque to operate or actuate the switch which means it may need more force to trigger. This model needs to rotate by 30 degrees for proper engagement which specifies the angular movement necessary for actuation. It comes in a physical height of 179.3 mm which is critical for installation and compatibility with different mounting spaces. This switch has a width of 66.8 mm which indicates that it follows standard mounting dimensions that makes it easier to integrate into existing systems. This module operates using a snap-lock mechanism that ensures a fast and reliable transition between on and off states which reduces arcing and increases durability. It comes with over travel feature which allows for extra movement beyond the actuation point and ensures that it activates reliably even if the motion overshoots slightly. The electrical contacts of this switch press against each other directly when actuated which ensures strong electrical conductivity.

The EA700-80001 limit switch contact configuration supports both normally open (NO) and normally closed (NC) operations. In this switch two normally open (NO) and two normally closed (NC) contacts which allows for multiple control options in electrical circuits. All materials used in the construction of this module are designed to withstand elevated temperatures. Also, in the manufacturing of this switch special lubricants that resist breakdown at high temperatures are used which reduces wear and friction for longer switch life.

Frequently Asked Questions about EA700-80001:

Q: Why does the EA700-80001 limit switch use silver alloy butt contacts?

A: Silver alloy butt contacts provide superior electrical conductivity and wear resistance. This ensures minimal voltage drop and reliable performance in high-load applications.

Q: How does the 30° travel angle of the EA700-80001 limit switch affect its precision?

A: The 30° travel angle ensures controlled actuation and minimizes accidental triggering. This feature is crucial for precision applications requiring consistent response and repeatability.

Q: What advantage does the over-travel feature in the EA700-80001 limit switch provide?

A: The over-travel feature allows extra movement beyond the actuation point, ensuring positive engagement. This prevents misalignment issues and enhances reliability in mechanical applications.

Q: Why is the EA700-80001 limit switch equipped with high-temperature lubricants?

A: High-temperature lubricants reduce wear and friction, ensuring smooth operation in extreme environments. This feature extends the switch’s operational life in demanding industrial settings.

Q: What makes the EA700-80001 limit switch suitable for industrial automation applications?

A: The EA700-80001 offers 2NO/2NC contacts and a snap-lock mechanism, making it ideal for automation control. Its high-temperature resistance ensures reliable operation in harsh environments.
