*1. Material specifications for stainless steel housing case: 1.4305 (W.-No.), SUS 303 (AISI), 2346 (SS). Please contact your OMRON representative for other stainless steel materials.
2. Please contact your OMRON representative for DC 2-wire models.
3. Stainless steel models are also available. Please contact your OMRON representative.
Note:M30 non-shielded Models with double sensing distance and short barrels cannot be mounted due to the necessary separation distance from the surrounding metal. Standard sensing models are thus available.
The E2A sensors are available with the following connectors and cable materials:
Pre-wired models

Standard cable lengths are 2m and 5m.
For other cable lengths please contact your OMRON representative.
Standard cable material: PVC (dia 4mm) -WP

Precautions
Safety Precautions
Power Supply
Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC model, otherwise it may be damaged.
Load Short-circuit
Do not short-circuit the load, or the E2A may be damaged.
The E2A's short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage range.
Correct Use
Designing
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms (160ms for NO+NC -B3 / -C3 types) after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load.
Effects of Surrounding Metal
When mounting the E2A within a metal panel, ensure that the clearances given in the following table are maintained.

Note 1. In the case of using the supplied nuts.
If true flash mounting is necessary, apply a free zone of 1.5mm
2. In the case of using the supplied nuts.
If true flush mounting is necessary, apply a free zone of 4mm
If true flash mounting is necessary, apply a free zone of 1.5 mm.
2. In the case of using the supplied nuts. If true flush mounting is necessary, apply a free zone of 4 mm.
Wiring
Be sure to wire the E2A and load correctly, otherwise it may be damaged.
Connection with No Load
Be sure to insert loads when wiring. Make sure to connect a proper load to the E2A in operation, otherwise it may damage internal elements.
Do not expose the product to flammable or explosive gases.
Do not disassemble, repair, or modify the product.
Power OFF
The Proximity Sensor may output a pulse signal when it is turned OFF. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor.
Power Supply Transformer
When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer.
Mutual Interference
When installing two or more Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.

| B | 60 | 100 | 120 | 200 | 300 | |
Wiring
High-tension Lines
Wiring through Metal Conduit:
If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning.
Cable Extension
Standard cable length is less than 200m
The tractive force is 50 N.
Mounting
The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity.
Do not tighten the nut with excessive force. A washer must be used with the nut.

| Type | Torque | |
| M8 | Stainless steel type | 9 Nm |
| Brass type | 4 Nm | |
| M12 | 30 Nm | |
| M18 | 70 Nm | |
| M30 | 180 Nm | |
Maintenance and Inspection
Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time.
- Check for mounting position, dislocation, looseness, or distortion of the Proximity Sensor and sensing objects.
- Check for loose wiring and connections, improper contacts, and line breakage.
- Check for attachment or accumulation of metal powder or dust.
- Check for abnormal temperature conditions and other environmental conditions.
- Check for proper lighting of indicators (for models with a set indicator.)
Never disassemble or repair the Sensor.
Environment
Water Resistivity
The Proximity Sensors are tested intensively on water resistance, but in order to ensure maximum performance and life expectancy avoid immersion in water and provide protection from rain or snow.
Operating Environment
Ensure storage and operation of the Proximity Sensor within the given specifications.
Inrush Current
A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor, in which case connect the load to the Proximity Sensor through a relay.
