Note: 1.Through-beam Photoelectric Sensors are used in a combination with an emitter and receiver, and so the model for each is given for discontinued models. If either the emitter or receiver of Through-beam Photoelectric Sensors are damaged, receivers and emitters for other series cannot be used together.
2.For recommended substitute products, the model numbers are given only for combinations of emitter and receiver.
3.The dimensions and other factors depend on Sensors. Refer to the following comparison overview.
2.Comparison Overview for OA-5/OA-5N and E3JK/E3JM
E3JK: Pre-wired (standard length: 2 m)
E3JM: Terminal block
Sensor dimensions
OA-5: 72 x 51 x 72 (H x W x D)
OA-5N: 72 x 51 x 75 (H x W x D)
E3JK: 50 x 18 x 50 (H x W x D)
E3JM: 65 x 25 x 75 (H x W x D)
See note 1.
L bracket mounting
hole pitch
OA-5: 42 mm
OA-5N: 32 mm (or 42 mm)
E3JK: 42 mm
E3JM: 42 mm
Power supply voltage
100/200 VAC
24 to 240 VAC
Control output
(R load)
Regular load: 200 AC, 0.3 to 1.5 A
Microload: 200 AC, 0.01 to 0.3 A
5 VDC, 10 mA to 250 AC, 3A
Operation mode
Dark-ON
E3JK: Depends on the model (relay output)
E3JM: Switch selectable
See note 2.
Note: 1.The mounting hole for the L bracket may be used as is for some models. In other cases, however, the mounting hole may need to be changed to adjust the light axis because of Sensors dimensions, in particular, narrowed width of the light emitting/receiving surface, which will misalign the light axis. 2.The operation mode refers to whether Sensors turn ON when light is received or when light is interrupted. A dark-ON E3JK-5M2 has been selected, but for E3JK Sensors with relay output, the operation mode depends on the model. E3JM is used with the internal switch set to dark-ON.
