Product Description:
The EA700-50001 Switch is manufactured under strict quality assurance standards by Danaher. It is related to the Snaplock Limit Switches series that is designed for industrial automation and other control systems.
The EA700-50001 switch has a specific type of contact configuration where the electrical contacts can change states in a predefined manner. It has a 1/2-inch National Pipe Thread (NPT) fitting, which is a standard size for electrical conduit connections which allows secure attachment of electrical wiring enclosures. It is included with four mounting holes with a 1/4-20 thread size, each hole being 0.38 inches deep which provides standardized options for securely fastening the switch to a surface. It is designed to withstand environmental conditions and ensures protection against water, oil, dust and other contaminants. It is also able to withstand high levels of gamma radiation up to 204 megarads which makes it suitable for use in nuclear or high radiation environments. All of its electrical contacts are made from a silver alloy, which provides excellent conductivity and resistance to corrosion and electrical wear. It is featured with gold plated contacts which enhance durability and improves conductivity especially in low voltage or low current applications. It is able to move through a total angular displacement of 90 degrees from one end to the other.
This EA700-50001 limit switch implements a cam action mechanism, which likely provides precise control of contact engagement and disengagement. It is constructed to accommodate electrical wiring up to size 12 American Wire Gauge (AWG), with terminal screws that make installation and connection easy. It is produced under strict quality assurance standards and meets nuclear industry requirements (10CFR50) and ANSI N45.2.
Frequently Asked Questions about EA700-50001:
Q: How does the cam action mechanism improve the performance of the EA700-50001 switch?
A: The cam action mechanism ensures precise and reliable contact engagement and disengagement. This improves operational efficiency and extends the lifespan of the switch.
Q: Why does the EA700-50001 switch feature both silver alloy and gold-plated contacts?
A: Silver alloy provides excellent conductivity and wear resistance, while gold plating enhances performance in low-voltage or low-current applications by preventing oxidation.
Q: How does the 90-degree total travel benefit the EA700-50001 switch operation?
A: The 90-degree total travel ensures a well-defined switching range, reducing false activations and ensuring accurate switching in industrial automation applications.
Q: Why is the EA700-50001 switch designed to accommodate up to size 12 AWG wiring?
A: Supporting size 12 AWG wiring allows it to handle higher current loads, ensuring safe and reliable electrical connections in demanding applications.
Q: How does the NEMA-rated enclosure enhance the durability of the EA700-50001 switch?
A: The NEMA-rated enclosure protects against water, oil, and dust, making it ideal for harsh industrial environments where contamination could affect performance.
