Product Description:

The EA170-24100 Switch of Danaher is a durable, reliable and suitable for various industrial automation applications. It belongs to the Snaplock Limit Switches series and its materials and enclosure ratings allow it to withstand harsh conditions.

The EA170-24100 switch actual weight is 3.5 lbs which helps determine installation feasibility, handling and mechanical compatibility with other components in a system. It comes with NEMA ratings such as NEMA1 which provides protection against dust and light indoor contaminants, NEMA4 which is essential for protection against water splashes, hose-directed water and limited external conditions. It also has NEMA 13 rating which ensures its protection against oil, coolants and non corrosive liquids which makes it suitable for industrial applications. This module has die cast zinc housing which ensures structural strength and durability and the stainless steel top cover and fasteners provide resistance to corrosion and mechanical stress. It can accommodate multiple wires which allows for versatile wiring configurations and ease of installation in control circuits. It is featured with two normally open (N.O.) and two normally closed (N.C.) contacts that allows for multiple connection possibilities and this setup enables both activation and deactivation signals in control circuits.

The EA170-24100 Switch uses screw terminals which means wires are secured using screws and it is a common connection in industrial environments for reliability and ease of maintenance. This module supports multiple mounting styles which makes it adaptable to different machine setups and is suitable for applications that require broader installation bases. It does not include a built in indicator (such as an LED) to show activation status which means external monitoring may be needed.

Frequently Asked Questions about EA170-24100:

Q: How does the die-cast zinc housing of EA170-24100 improve durability?

A: The EA170-24100 switch features a die-cast zinc housing, which enhances structural strength and impact resistance. This design ensures longevity in harsh industrial environments.

Q: Why does the EA170-24100 Switch use gold-plated contacts instead of standard contacts?

A: Gold-plated contacts reduce oxidation and minimize electrical resistance. This ensures reliable signal transmission and long-term performance in high-demand automation systems.

Q: How do the screw terminals in EA170-24100 ensure secure electrical connections?

A: Screw terminals provide a firm grip on conductors, preventing accidental disconnections. They also allow for easy maintenance and rewiring in industrial applications.

Q: What makes the NEMA 13 rating important for EA170-24100 in industrial environments?

A: The NEMA 13 rating protects against oil, coolants, and non-corrosive liquids. This is crucial for machinery exposed to lubricants or cutting fluids.

Q: Why does the EA170-24100 Switch have 2 N.O. and 2 N.C. contacts?

A: This configuration enables simultaneous activation and deactivation in control circuits. It also provides redundancy for fail-safe switching in automation processes.
