What Substitute Products Are Recommended For OA-5 Or OA-5N Through-Beam Photoelectric Sensors With Built-In Power Supply?

1.They depend on the specific model of OA-5 or OA-5N. Check using the following table.

Connection method	Control output relay	Discontinued model (See note 1.)			Recommended substitute model (See note 2.)	Remarks
Connection method	Control output relay	Emitter	Receiver	Combination	Recommended substitute model (See note 2.)	Remarks
Pre-wired	General load	OA-5L	OA-5D	OA-5	E3JK-5M2	See note 3.
Terminal block	General load	OA-5LN	OA-5DN	OA-5N	E3JK-10M4
Terminal block	Microload	OA-5LN	OA-5DNC	OA-5NC	E3JK-10M4

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

Item	OA-5 or OA-5N	E3JK or E3JM	Remarks
Connection method	OA-5: Pre-wired (standard length: 30 cm) OA-5N: Terminal block	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	See note 1.
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.
