EA080-21100 by Danaher

The EA080-21100 from Danaher is a precision-engineered limit switch in the renowned Snaplock Limit Switches series, designed for demanding industrial environments. It features a robust Die-cast zinc housing that provides exceptional corrosion resistance and mechanical strength. The switch employs a rocker-type SNAP-LOCK® operating mechanism for rapid make-and-break action, and its 1NO/1NC SPDT contact configuration delivers reliable switching performance. Rated for a wide Standard Temperature Range of –20°C to +90°C and an extended High Temperature Range up to +150°C, this switch offers versatility where temperature extremes are encountered. It also meets stringent NEMA Ratings 1, 4, and 13 for protection against dust, water, and oil spray.

Technical capabilities of the EA080-21100 include a Continuous Current Rating (AC) up to 125 VAC at 20 A (250 VAC at 15 A, 480 VAC at 10 A, and 600 VAC at 5 A) and a Continuous Current Rating (DC) of up to 125 VDC at 5 A (250 VDC at 1.5 A). The Contact Material of silver alloy ensures low contact resistance and high conductivity, minimizing voltage drop and contact wear. With a precise Mechanical Travel of 10° trip travel and a Power Factor range from 75–100%, this limit switch guarantees accurate actuation with minimal bounce. The Housing Material of die-cast zinc complements its Operating Mechanism by resisting deformation under mechanical stress. Installers can choose between Standard and Wide mounting options to accommodate various panel thicknesses and chassis configurations.

Operational features of the EA080-21100 promote maximum uptime and minimal servicing. The quick make-and-break FORM Z contact design reduces contact chatter and increases switch life under heavy cycling. Its dual temperature rating (–40°C to +90°C low range, 0°C to +150°C high range) enables deployment in freezers, ovens, and other extreme settings without sacrificing performance. The sealed die-cast housing combined with NEMA 1, 4, and 13 compliance shields internal components from contaminants, moisture, and mechanical impact. End users benefit from the switch’s maintenance-free operation and consistent actuation threshold, ensuring predictable machine control.

Integration of the EA080-21100 into industrial automation systems is straightforward: the SPDT contacts interface seamlessly with PLC inputs and relay logic, while the SNAP-LOCK® mechanism simplifies mechanical linkage to actuator levers or arms. Its compact footprint and multiple Mounting Options allow retrofit into existing control panels or OEM machinery. Common applications include conveyor end-of-travel detection, safety interlocks on packaging lines, and position sensing in robotic assemblies. With its proven reliability, the EA080-21100 limit switch is an ideal solution for engineers specifying high-quality components in automotive, food and beverage, material handling, and process control environments.
