Vibration Sensor

Safety Precautions

This Sensor is a precision device. Do not drop it or subject it to

excessive shock or force. Doing so could break it or change its

characteristics. Do not use the Sensor if it has been dropped.

 Operating Environment

• Do not use the Sensor in locations with volatile, flammable, or

corrosive gas (organic solvent vapor, sulfite gas, chlorine, sul-

fide gas, ammonia gas, etc.) or other toxic gases. They may

cause the Sensor to break down.

• Do not use the Sensor in locations subject to fresh water, salt

water, water drops, or splattering oil.

• Do not use the Sensor in an environment where condensation

or icing may occur. Moisture freezing on the Sensor may

cause output to fluctuate or may cause the Sensor to break

down.

• Do not use the Sensor in locations subject to direct sunlight.

Doing so may cause the Sensor to break down.

• Do not use the Sensor in locations subject to direct radiant

heat from heating equipment. Doing so may cause the Sensor

to break down.

• Do not use the Sensor in locations with severe temperature

changes. Doing so may cause the Sensor to break down.

• Do not use the Sensor in environments with excess mechani-

cal stress. Doing so may cause the Sensor to malfunction or

break down.

• Do not use the Sensor in locations with large vibration or

shock. These may cause the Sensor to break down.

• Do not use the Sensor in locations with strong electrical or

magnetic fields. These may cause the Sensor to break down.

 Countermeasures against Noise

• The Sensor does not contain any protective circuits. Never

allow the electrical load to exceed the absolute maximum rat-

ings. Such loads may damage the circuits. If required, install

protective circuits so that absolute maximum ratings are not

exceeded.

• Allow as much space as possible between the Sensor and

devices that generate surges or high frequencies (such as

high-frequency welders and high-frequency sewing

machines). Attach a surge protector or noise filter on nearby

noise-generating devices (in particular, motors, transformers,

solenoids, magnetic coils, or other devices that have an induc-

tance component).

• Wire the Sensor away from high-voltage and large-current

power lines in order to prevent inductance noise. It is also

helpful to separate conduits and ducts and to use shielded

cables.

• When using a switching regulator, power supply switching

noise may cause malfunctions, so check this before use.

 Handling

• Static electricity can destroy the Sensor. Take countermea-

sures including grounded work benches, floors, and other

charged objects and workers.

• Do not handle the Sensor in locations with excessive vapor,

dust, dirt, etc.

• Do not hold the Sensor with pliers, tweezers, or similar tools,

and do not subject components to damage or excessive shock

due to inadequate adjustment of the mounter.

• When placing components near the edge of the PCB or near a

connector, make sure that stress is not applied to the Sensor

when the device is assembled or when the connector is con-

nected or disconnected.

• Do not apply any external force to components after soldering

until everything has cooled off and do not allow mechanical

stress due to PCB warping or other factors.

• Under some usage conditions, ultrasound may cause the Sen-

sor to resonate and be destroyed. OMRON cannot specify the

detailed conditions under which the Sensor will be used, so we

assume no responsibility if the Sensor is used in environments

where ultrasound is used. If the Sensor must be used in an

environment with ultrasound, check its performance in the

actual environment beforehand.

• Stress due to plastic hardening may change Sensor character-

istics. Do not mold seal the Sensor after mounting.

• When applying a moisture preventing coating or other coating

after mounting the Sensor, select a coating with minimal stress

and check operation carefully.

• Do not attempt to disassemble or modify the Sensor.

• Do not use the Sensor in safety devices or for applications in

which Sensor operation would directly affect human life.

• Carefully read the precaution in the Instruction Manual before

using the Sensor.

• In addition, if you use the Sensor under conditions other than

those in these specifications, check Sensor operation under

those conditions beforehand.

 Shipping and Storage

• Do not store the Sensor in locations with harmful corrosive gas

(organic solvent vapor, sulfite gas, sulfide gas, etc.)

• The Sensor is not drip proof, so do not store it anywhere that

water might get on it.

• Store the Sensor within appropriate temperature and humidity

ranges.

* Before storing the Sensor in an environment other than the

environment recommended by OMRON, evaluate the results

in the actual storage environment and judge whether or not

storage there is appropriate.

• Do not store the Sensor in locations with excessive vapor,

dust, dirt, etc.
