Eaton E50AT1 Plunger Limit Switch

The Eaton E50AT1 is a heavy-duty industrial limit switch with a top-mounted plunger actuator. It provides one normally closed and one normally open contact rated at 10 amps at 600 volts AC. The standard body carries NEMA 3, 3S, 4X and 6P ratings for surface mounting in harsh environments.

Suits control panels needing top actuation

This switch suits automation systems where a vertical plunger movement triggers the circuit. It is not for applications requiring a lever, roller or wobble actuator style. Buyers needing a boot-sealed plunger or a DC contact rating should look at other models.

10A 600V AC contact rating decides fit

The single specification that determines compatibility is the 10 amp at 600 volt AC contact rating. The DC contact rating is not rated, so the switch cannot switch DC loads. Verify the control circuit voltage and current match this AC rating before installation.

Questions about this item

Will the 1.44 in plunger actuator on this Eaton E50AT1 line up with the cam on my existing machine?

The plunger actuator extends 1.44 in from the top of the switch body, so measure your cam travel against that length before mounting.

How can I confirm the 1NC/1NO contacts are switching correctly at 10A 600V AC after installation?

With power off, use a multimeter on each contact pair; the normally closed circuit should open and the normally open circuit should close when the plunger is depressed 1.44 in.

Does the switch include mounting hardware or a wiring connector in the box?

The switch body measures 3.13 in high, 1.54 in wide and 1.78 in deep with surface-mount holes; mounting screws and wire terminals are not supplied.
