2 CAUTIONS

Make sure that the power supply is off while wiring.

Take care that wrong wiring will damage the sensor.

Verify that the supply voltage variation is within the rating.

If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.

Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. Extension up to total 100m, is possible with 0.3mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible. Do not use during the initial transient time (50ms) after the power supply is switched on.

Take care that the sensor is not directly exposed to fluorescent lamp from a rapid-starter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance.

Avoid dust, dirt, and steam. Do not use it in places having excessive vapor, dust, etc., or where it may come in direct contact with corrosive gas.

Take care that the sensor does not come in direct contact with water, oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.

Make sure that stress by forcible bend or pulling is not applied directly to the sensor cable joint. Since the cable end is not waterproof, do not use the sensor in the application where water may seep in from the cable end.

When connecting the mating cable to the connector type sensor, the tightening torque should be 0.4N m or less.

3 MOUNTING

The tightening torque should be 0.8N m or less.

(Optional)

Care must be taken regarding the sensor mounting direction with respect to the object's direction of movement.

Sensing object

Do not make the sensor detect an object in this direction because it may cause unstable operation.

When detecting a specular object (aluminum or copper foil, etc.) or an object having a glossy surface or coating, please take care that there are cases when the object may not be detected due to a small change in angle, wrinkles on the object surface, etc.

When a specular body is present below the sensor, use the sensor by tiling it slightly upwards to avoid wrong operation.

No good	Good
Specular face	Specular face

Tilt

If a specular body is present in the background, wrong operation may be caused due to a small change in the angle of the background body. In that case, install the sensor at an inclination and confirm the operation with the actual sensing object.

Some object may produce the dead zone right in front of the sensor.

5 AUTOMATIC INTERFERENCE PREVENTION FUNCTION

EQ-30 series is incorporated with automatic interference prevention function.

Up to two sets of sensors can be installed close together.

Close mounting of two sensors

6 STABILITY INDICATOR

Since the EQ-30 series uses a 2-segment photodiode as its receiving element, and sensing is done based on the difference in the incident beam angle of the reflected beam from the sensing object, the output and the operation indicator operate according to the object distance. Further, the stability indicator shows the margin of the incident light intensity and not that of the object distance.

Hence, the distance at which it lights up/off depends on the object reflectivity and is not at all related to the output operation. Do not use the sensor when the stability indicator is off (unstable light received condition), since the sensing will be unstable.

Notes: 1) Use the accessory adjuster screwdriver to turn the distance adjuster slowly. Turning with excessive force will cause damage the adjuster.

2)The Far (Main) distance adjustment should be done before the Near (Sub) distance adjustment. Take care that the Near (Sub) setting distance changes with change in the Far (Main) setting distance.
