Eaton E51SPL

File E51 Sensors are comprised of 

three modular components, easily assembled to form a complete 

device. The components consist of 

a sensor head, a solid state plug-in 

switch and a wiring receptacle.

Any E51 Inductive Proximity, Photoelectric Fiber Optic Sensor Head 

may be used with the E51SNL or 

E51SPL switch bodies, allowing 

easy installation and modification of 

switch function and sensing characteristics. The switch body plugs into the 

Eaton E51RN Wiring Receptacle, and 

connections to the line and loads are 

made according to the diagram below.

Description:

The resettable short circuit protection feature built into these 

switches will turn the output off if the load is shorted or the output 

is inadvertently applied across the DC power supply. When the protection feature operates, it causes the light emitting diode for that 

output to turn OFF, as a fault indication. The output can be reset by 

cycling power, or by moving a target in and out of the sensing range.

When power is first applied to the switch bodies, both N.O. and 

N.C. outputs will be open and both LEDs will be off. At the end of 

this “time before availability” period the outputs will be open or 

closed, as determined by the signal for the sensor head.

INSTALLATION

File E51 Switches may be wired into common conduit with wiring 

from other AC or DC control devices. Grounding by means of the 

grounding terminal provided in the wiring receptacle is optional or 

as required by the applicable electrical code.

Caution: E51SNL and E51SPL switches must always be connected 

with a suitable load. They should not be connected to 

relays whose pick-up currents exceed their maximum current 

rating. They should not be connected to incandescent 

lamp loads which exceed their incadescent steady state 

current rating. If the load current rating is exceeded, the 

short circuit protection feature may cause faulty operation.
