Basic Information
Long range sensing capability to 2.5 m 8.202 ft
Stable sensing unaffected by color or material
UL/C-UL,CE,GB,UKCA Approved
UL : Recognition
GB : Multi-voltege type only
Features
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.
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.)
Hardly affected by background objects
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.
Convenient terminal block type
Cabling enabled by way of a terminal block that eliminates waste.
An easy to set adjuster with indicator
Equipped with a 2-turn adjuster with indicator, making it easy to set for short or long distances.
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.

Multi-voltage [EQ-50□]
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)
BGS / FGS functions make even the most challenging settings possible!
＜The BGS function is best suited for background not 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).
This is useful if the object and background are far apart.
Not affected if the background color changes or someone passes behind the conveyor.
＜The FGS function is best suited for background present＞
- 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.).
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.

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.

Mounting
The tightening torque should be 0.8 N·m or less.
Care must be taken regarding the sensor mounting direction with respect to the object’s direction of movement.
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 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.
- Note that the detection may be unstable depending on the mounting conditions or the sensing object to be used.
In the state that this product is mounted, be sure to check the operation with the actual sensing object to be used.
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).
Note:
Use crimp terminals with insulating sleeves.
Recommended crimp terminal: Nominal size 1.25 × 3.5 0.049 × 0.138.
- The tightening torque for the terminal screws should be 0.3 to 0.5 N·m.
Part description
Notes:
1)The operation mode switch of the DC-voltage type is the DIP switch.
Refer to ‘DC-voltage type’ of ‘Operation mode switch’ for details.
2)Incorporated on EQ-5□T only.
Operation mode switch
Multi-voltage type (L-ON / D-ON mode only)
| Operation mode switch | Description |
|---|---|
 | Detection-ON mode is obtained when the switch is turned fully clockwise (L side). |
 | Detection-OFF mode is obtained when the switch is turned fully counterclockwise (D side). |
Note:
Turn the operation mode switch gradually and lightly with the attached screwdriver. Turning with excessive strength will cause damage to the adjuster.
DC-voltage type
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.
Timer function (EQ-5□T only)
- EQ-5□ 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.
Timer period: T = 0.1 to 5 sec. (variable)
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
- This product has been developed / produced for industrial use only.
- This product is suitable for indoor use only.
- 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.
