EQ-500 Series – Adjustable Range Reflective Photoelectric Sensor – Panasonic Photoelectric Sensors
USD $ 101.01 – USD $ 192.99
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. |
 |
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!
|
|
– 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. |
