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 |

Note:UL-listed models have the -US suffix. Through-beam models have -US suffix instead of -N suffix. (Example: E3JM-10M4-US 2M). Tightening nuts, washers, and rubber bushings are not provided with these models.
Change: Shape of the E3JM conduit socket
Note, however, that DC-type E3JK SSR Output Models are not UL-listed.
*1.The model number of the Emitter is E3JK-5L-N 2M for all models. In order from the top of the model number of the Receivers are E3JK-5DM1-N 2M, E3JK-5DM2-N 2M, and E3JK-5DS3-N 2M. Orders for individual Emitters and Receivers are accepted.
*2.Values in parentheses indicate the sensing distance when using E39-R2 Reflectors.
