Technical Bulletin

Eaton E47 precision limit switches are an ideal cost-
effective solution for applications requiring high
switching accuracy. The switches have high-performance
specifications for current capacity, operating force and
travel characteristics. Output is rated up to 20A, so a direct
circuit without relays can be designed. This allows less
wiring and quicker installation, and reduces the number of
components that could fail over time. The E47 is available
with a wide variety of operator actuators, including lever,
plunger and roller combination styles. For applications
requiring actuator protection, the E47 is available enclosed
in a rugged metal housing. With so many options, E47
precision limit switches are perfect for interacting with
or customizing to your application, while providing an
industry-leading service life.
Designed for highly accurate switching
Precise problem solver
With many different switch
configurations, Eaton can
provide solutions to the most
demanding applications. The E47
offers operating forces from as
low as 0.35 ounces to as high
as 28.22 ounces and pre-travel
limits as low as 0.016 of an inch.
The E47 has a wide variety of
operating styles available to meet
the application’s requirements.
