## **Long range sensing capability to 2.5 m 8.202 ft Stable sensing unaffected by color or material** 

## **Long sensing range** 

An adjustable range to 2.5 m 8.202 ft allows plenty of space for installation. 

1 m 3.281 ft sensing range type also available. Adjust the volume easily to suit your needs when using at close range. 

## **Hardly affected by background objects** 

## **Impervious to variations color or angle** 

The optical system has been optimized. Since the sensor is hardly influenced at all by angles or the gloss of objects compared to the previous model, it is possible to detect both white objects and black objects at almost 

a constant distance. The difference in sensing range between white non-glossy paper and gray non-glossy paper (lightness: 5) is approx 5% | when set at a distance of 2 m 6.562 ft. 

Because the sensor doesn’t detect objects outside the preset sensing field by using the 2-segment photodiode adjustable range system, it will not malfunction even if someone walks behind the sensing object or machines or conveyors are in the background. 

Note: Please note that malfunction may occur when there are specular objects or objects with a mirror-like surface in the background. Refer to p.7 “ **Mounting** ” of “ **PRECAUTIONS FOR PROPER USE** ” section. 

## ~~©~~ **MOUNTING OPERABILITY** 

## **Convenient terminal block type** 

Cabling enabled Terminal block by way of a terminal block that eliminates waste.

## ~~ee~~ **APPLICATIONS** 

**Level check within the hopper** The distance to the object can be set to enable residual amount sensing in the hopper regardless of color. 

**Confirmation of the passage of packages on a conveyor belt** Can accurately detect packages even if they vary in size and color. 

## ~~ee~~ **VARIETIES** 

## **Equipped with both NPN and PNP outputs EQ-51** □ 

We’ve added a DC-voltage type with NPN and PNP transistor outputs all in one sensor. Its BGS/FGS function controls any background effects for more stable sensing. 

**EQ-50** □ 

## **Multi-voltage** 

Because it can function with 24 to 240 V AC and 12 to 240 V DC, almost any power supply anywhere in the world will do. 

## **Convenient timer function models** 

Types with an ON-delay/OFF-delay timer available. OFF-delay, e.g. useful when the response of the connected device is slow, ON-delay, e.g. useful to detect objects that take a long time to move. 

- Operation: ON-delay, OFF-delay 

- Timer period:  0.1 to 5 sec. (individual setting possible) 

## ~~e~~ **FUNCTIONS** ~~e~~ 

**EQ-51** □ 

## **BGS/FGS functions make even the most challenging settings possible!** 

**The BGS function is best suited for background not present** 

**The FGS function is best suited for background present** 

**When object and background are separated BGS (Background suppression) function** The sensor judges that an object is present when light is received at position A of the light-receiving element (2-segment element). 

**When object and background are close together** 

**When the object is glossy or uneven FGS (Foreground suppression) function** The sensor judges that no object is present when light is received at position B of the light receiving element (2-segment element) (The conveyor is detected). This function is useful if the object and the background are close together or if the object is glossy or uneven. However, sensing is impossible if there is no background (conveyor, etc.). 

This is useful if the object and background are far apart. Not affected if the background color changes or someone passes behind the conveyor.

## ~~a~~ **ENVIRONMENTAL RESISTANCE** 

## **Little affected by contamination on lens** 

Even if the lens surface gets somewhat dirty from dust particles, there is very little change in the operation field, by usage adjustable range system. 

## **Waterproof** 

The sensors features an IP67 rating to allow their use in process lines where water is used or splashed. 

Note:  If water splashes on 

the sensor during sensing operation, 

it may sense water as an object.

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

- If a specular body is present in the background, faulty 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. 

- When a specular body is present below the sensor, use the sensor by tilting it slightly upwards to avoid faulty operation.

- This product is not easily affected by the reflected light intensity since this sensor is the adjustable range reflective type. When the reflected light intensity is remarkably low, the sensing range may be affected. In that case, mount the sensor, while checking light-up of the stable indicator (green). 

- The mounting screws of the terminal cover and VR cover should certainly be tightened to maintain water-resistance; the tightening torque of the screws should be 0.3 to 0.5 N·m. 

## **Automatic interference prevention function** 

- When the sensors are mounted closely, use them in the interference prevented area, as shown below.

## **PRECAUTIONS FOR PROPER USE** 

## **Wiring** 

- Check all wiring before applying power since incorrect wiring may damage the internal circuit. Also, carefully tighten the terminal screws so that the wires of adjacent terminals do not touch. 

- The mounting hole for the terminal cover fixing screws inclines 70 degrees to the terminal cover, as shown in the figure below. 

To avoid damaging this product or screw, take care when tightening or loosening a screw.

- To maintain water-resistance, the cable should have an outer diameter between ø9 to ø11 mm ø0.354 to ø0.433 in with a smooth covering material that allows the attached conduit connector to be securely tightened; the tightening torque of the screw should be of 1.5 to 2.0 N·m. 

- If an external surge voltage exceeding 4 kV is impressed (DC-voltage type: 1 kV), the internal circuit will be damaged, and a surge suppressing element should be used. 

- Prepare the cable end as shown below.

Note:  When assembling the conduit connector, pay attention to the direction of the gland packing. Furthermore, in order to maintain water-resistance, fit the gland packing such that the seating surface of the gland packing contacts the packing holder part of the terminal cover evenly. 

- The size of conduit is M20 × 1.5 mm 0.787 in. 

- If pressure terminals are to be used, affix the connected pressure terminals to a terminal (M3.5 screw).

## **BGS/FGS function (DC-voltage type only)** 

- DC-voltage type sensor incorporates BGS/FGS function. Select either the BGS or FGS function depending on the positions of the background and sensing object. 

- BGS/FGS function is set with the operation mode switch. 

- FGS function is used when the sensing object contacts the background (conveyor, etc). 

- Depends on a selection of either BGS or FGS function, the output operation changes as follows.

## **PRECAUTIONS FOR PROPER USE** 

## **Timer function (EQ-5□T only)** 

- **EQ-5□T** incorporates an OFF-delay timer, which is useful when the response of the connected device is slow, etc., and an ON-delay timer, which is useful for detecting objects that move slowly, for example. 

- The OFF-delay and ON-delay timers can be used simultaneously. 

- For DC-voltage type, set the DIP switch for the timer mode to ‘Timer ON’ side.

## **Stability indicator** 

- Since the **EQ-500** 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 (orange) operate according to the object distance. 

Furthermore, the stability indicator (green) shows the margin of the setting distance.

## **Others** 

- Do not use during the initial transient time (50 ms) after the power supply is switched on. 

- Its distance adjuster is mechanically operated. Do not drop; avoid other shocks. 

Timer period: T = 0.1 to 5 sec. (variable)
