Caution for Through-beam Type of E3JM/E3JK

In order to get CCC and CE marks of certification, a design change was made for E3JM/E3JK. The receivers and emitters of the former product and the redesigned product are not interchangeable. Using these products together could lead to operation failure. When either a receiver or an emitter needs replacement, please change both as a set.
Look for the "N" suffix on the product code to indicate the new, redesigned version. Consult the table below for use of the former and redesigned receivers and emitters.

Emitter	Receiver	Operation
Former emitter	Former receiver	OK
Redesigned emitter	Redesigned receiver	OK
Redesigned emitter	Former receiver	OK
Former emitter	Redesigned receiver	NG

Sensors

Connection method: Terminal block
Operation mode: Light-ON, Dark-ON (switch selectable)

Reflectors

(A Reflector is required for each Retro-reflective Sensor.)
The E39-R1 Reflector is provided with the Sensor. Order other Reflectors separately if required.

Name	Sensing distance		Model	Quantity	Remarks
Reflectors	E3JM-R4[]4(T)	4 m	E39-R1	1	Provided with the E3JM-R4[]4(T), E3JM-R4[]4(T)-G and E3JM-R4[]4(T)-US Models.

Note: Refer to Reflectors on E39-L/E39-S/E39-R on your OMRON website for details.

Mounting Bracket

Some Mounting Brackets are provided with the Sensor. Order other Mounting Brackets separately if required. (Refer to E39-L/E39-S/E39-R)
