Product Dimensions：

Customer connections to the sensor are made through the Catalog 

No. E51RN receptacle. Mechanical keying prevents other Eaton 

wiring receptacles from being used with the three-wire DC switch 

bodies. This will prevent the inadvertent installation of an AC switch 

body from being connected to a receptacle wired from a DC source, 

for example.

E51SNL and E51SPL Solid State Switches both have a normally 

open and normally closed (N.O. & N.C.) complementary output configuration (refer to “Wiring Diagrams” below).

Both devices have factory-installed light emitting diodes which signify 

switch closure for both N.O. and N.C. contacts. These devices are 

also protected from damage should reverse polarity DC voltage be 

applied to them

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.

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.
