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
