E2A-S08LS02-WP-B1-2M - Omron

E2A Cylindrical Proximity Sensor 1

Cylindrical Proximity Sensor

E2A

Safe Mounting with Greater

Sensing Distance

• Ensures a sensing distance approximately 1.5 to 2

times larger than that of any conventional OMRON

Sensor.

• Problems such as the collision of workpieces are

eliminated.

• Full range of standard sizes (M8, M12, M18 and

M30; both long and short barrels)

• Modular construction simplifies customization.

Please read and understand this catalog before purchasing

the products. Please consult your OMRON representative if

you have any questions or comments.

the surrounding metal. Standard sensing models are thus available.

■DC 3-wire Models

Note 1. The response frequency is an average value. Measurement conditions are as follows: standard target, a distance of twice the standard

target distance between targets, and a setting distance of half the sensing distance.

2. When using any model at an ambient temperature between −40°C and −25°C and a power voltage between 30 and 32 VDC, use a load

current of 100 mA max.,

3. For USA and CANADA : use class 2 circuit only.

14 E2A Cylindrical Proximity Sensor

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.

Wiring

Be sure to wire the E2A and load correctly, otherwise it may be dam-

aged.

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 ele-

ments.

Do not expose the product to flammable or explo-

sive gases.

Do not disassemble, repair, or modify the product.

■Correct Use

Designing

Power Reset Time

The Proximity Sensor is ready to operate within 100 ms after power

is supplied. If power supplies are connected to the Proximity Sensor

and load respectively, be sure to supply power to the Proximity Sen-

sor before supplying power to the load.

Effects of Surrounding Metal

When mounting the E2A within a metal panel, ensure that the clear-

ances given in the following table are maintained.

(Unit: mm)

Note 1. In the case of using the supplied nuts.

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.

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 sup-

ply 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.

E2A Cylindrical Proximity Sensor 15

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 pre-

vent against Proximity Sensor damage or malfunctioning.

Cable Extension

Standard cable length is less than 200 m.

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.

Maintenance and Inspection

Periodically perform the following checks to ensure stable operation

of the Proximity Sensor over a long period of time.

1. Check for mounting position, dislocation, looseness, or distortion

of the Proximity Sensor and sensing objects.

2. Check for loose wiring and connections, improper contacts, and

line breakage.

3. Check for attachment or accumulation of metal powder or dust.

4. Check for abnormal temperature conditions and other environ-

mental conditions.

5. Check for proper lighting of indicators (for models with a set indi-

cator.)

Never disassemble or repair the Sensor.

Environment

Water Resistivity

Do not use the Proximity Sensor underwater, outdoors, or in the rain.

Operating Environment

Be sure to use the Proximity Sensor within its operating ambient

temperature range and do not use the Proximity Sensor outdoors so

that its reliability and life expectancy can be maintained. Although

the Proximity Sensor is water resistive, a cover to protect the Prox-

imity Sensor from water or water-soluble machining oil is recom-

mended so that its reliability and life expectancy can be maintained.

Do not use the Proximity Sensor in an environment with chemical

gas (e.g., strong alkaline or acid gasses including nitric, chromic,

and concentrated sulfuric acid gases).

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.
