Product Description:

The EA170-41100 is a Snaplock limit switch from the Danaher series. It offers reliable position sensing by detecting the movement of mechanical components and ensuring that equipment operates within predefined limits. With its durable construction and simple installation process, the switch is designed to support efficient automation and control in industrial environments. This module features two normally open contacts that ensure that the circuit remains open (off) until the switch is triggered. This provides a clear indication that the component has reached its desired position. It also features two normally closed contacts that ensure that the circuit is continuously energized until the switch interrupts it.

The EA170-41100 is built to NEMA 1, 4, and 13 standards, ensuring its durability and protection in a variety of industrial environments. NEMA 1 provides basic protection against dust and accidental contact with the electrical components, making it suitable for indoor applications. NEMA 4 ensures that the switch is protected against splashing water, rain, and hose-directed water, offering greater versatility for use in outdoor or wet environments. The NEMA 13 compliance means the switch is resistant to dust and can withstand the cleaning procedures common in industrial settings. Together, these NEMA ratings guarantee that the EA170-41100 operates reliably across diverse conditions, making it ideal for manufacturing, material handling and machinery applications.

This limit switch features an adjustable lever with increments of 7°30' over a total range of 173°. This design allows for precise positioning of the lever, offering flexibility in fine-tuning the switch’s activation point. The lever can be adjusted in small, consistent increments to meet specific operational needs. This allows it to be used in a variety of applications, ensuring easy customization for different mechanical movements.
