Product Description:

The Danaher EA180-12302 is a high-performance limit switch designed to convert mechanical motion into electrical control signals. The switch operates through a mechanical actuator that detects movement and transmits electrical signals, ensuring precise system control. This switch is an essential component in automation systems, enhancing the accuracy and efficiency of industrial processes by providing feedback for machine operations. Its flexible electrical circuit control is facilitated by versatile open and closed contacts that deliver different switching options to suit a wide range of application requirements.

The use of silver alloy enhances the overall longevity and efficiency of the EA180-12302, ensuring high reliability and an extended service life. This alloy makes the contacts highly conductive and minimizes resistance for reliable operation. This material also provides superior resistance to corrosion and oxidation, helping maintain consistent performance over time. This switch allows precise positioning across a 167° range allowing users to tune the switch’s activation point based on their particular application requirements. The incremental adjustment provides a high level of precision in control, making it easy to adapt the switch to different operational needs.

The EA180-12302 measures 6.58 inches in height, 2.25 inches in width, and 4.12 inches in depth. This streamlined size is compact yet robust enough to maintain powerful performance in a wide range of setups. The switch is built for durability and comes with a durable housing that is resistant to dust, moisture and other types of contaminants in adherence to NEMA environmental protection standards. This unit offers broad flexibility in operating conditions and can perform optimally within an ambient range of -20°C to +90°C. This allows the switch to handle a wide range of operating conditions without compromising accuracy or durability.
