Omron E2A-M08KS02-M1-C1 Cylindrical proximity sensor Datasheet

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.

Precautions
■ Safety Precautions
Wiring
Power Supply
Be sure to wire the E2A and load correctly, otherwise it may be damaged.
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.
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.
■ Correct Use
Power OFF
Designing
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 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 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.
l
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.

Wiring
Maintenance and Inspection
High-tension Lines
Periodically perform the following checks to ensure stable operation
of the Proximity Sensor over a long period of time.
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 200 m.
The tractive force is 50 N.
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 environmental conditions.
5. Check for proper lighting of indicators (for models with a set indicator.)
Mounting
Never disassemble or repair the Sensor.
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.
Environment
Do not tighten the nut with excessive force. A washer must be used
with the nut.
Water Resistivity
Do not use the Proximity Sensor underwater, outdoors, or in the rain.

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 Proximity Sensor from water or water-soluble machining oil is recommended 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.
