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. Through-beam Sensors are normally sold in sets that include both the Emitter and Receiver.
Orders for individual Emitters and Receivers are accepted.
*2. Values in parentheses indicate the sensing distance when using E39-R2 Reflectors.
Accessories (Order Separately)
Slit (A Slit is not provided with the Sensor for through-beam. Order a Slit separately if required.) (Refer to Dimensions on page 12.)
Reflectors (A Reflector is required for Retroreflective Sensors.)
A Reflector is provided with the E39-R1 Sensor. For other Sensors, order a Reflector separately if required.
(Refer to Dimensions on E39-L/F39-L/E39-S/E39-R.)
Note: 1. When using any reflector other than the provided one, use a sensing distance of approximately 0.7 times the typical value as a guide.
2. Refer to Reflectors on E39-L/F39-L/E39-S/E39-R for details.
* Values in parentheses are the minimum required distance between the Sensor and Reflector.

Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use the product in atmospheres or environments that exceed
product ratings.
● Designing
Operation Note: The white part of the DIP switch indicates which setting is selected.
Output Relay Contact
If E3JM/E3JK is connected to a load with contacts that spark when the load is turned OFF (e.g., a contactor or valve), the normally-closed side
may be turned ON before the normally-open side is turned OFF or vice-versa. If both normally-open output and normally-closed output are used
simultaneously, apply an surge suppressor to the load.
Refer to OMRON’s PCB Relays Catalog (X33) for typical examples of surge suppressors.

E3JM/E3JK
● Wiring
Connecting and Wiring
•We recommend connecting a cable with a conductor cross-section
of 0.3 mm2 and an outer diameter of 6 to 8 mm.
•Be sure to firmly tighten the cover in order to maintain waterproof
and dustproof properties. The screw size of the conduit sockets is
shown in the following table.
Cable End Treatment
Recommended Crimp Terminal Dimensions (Unit: mm)
Note: Use terminals with insulation tube (recommended crimp terminal: 1.25 to
3.5).
● Others
Terminal Protection Cover (Provided)
The terminal protection cover is designed to improve safety by
maintaining the sensitivity properties of the product and by preventing
any contact with charged sections while it is being operated with the
mode set to the timer mode. Mount the product as shown in the
following diagram (mount the Through-beam Model on the Receiver
side).
● Designing
Power Reset Time
The Sensor is ready to detect within 200 ms after it is turned ON. If
the Sensor and load are connected to separate power supplies, be
sure to turn ON the Sensor first.
● Wiring
Connecting and Wiring DC SSR Output Models
When using the DC SSR output model, the total of the load current for
the Light-ON output (NO) and that for the Dark-ON (NC) should be
100 mA max. If the total exceeds 100 mA, the load short-circuit
protection function will be activated (this function will be reset when
the power of the Photoelectric Sensor is turned OFF).
● Others
Ambient Conditions (Installation Area)
The E3JM will malfunction if installed in the following places.
•Places where the E3JM is exposed to a dusty environment.
•Places where corrosive gases are produced.
•Places where the E3JM is directly exposed to water, oil, or
chemicals.
