Features

基本性能向上

Response frequency of 5 kHz* allows the use of high-speed application

* In the case of GX-303S

The GX-303S boasts a response frequency of 5 kHz and realizes high speed response.
The response frequency of other sensor models has been also improved by up to 4 times as compared to our conventional models.
Since the GX-300 series responds quickly to sensor ON/OFF judgement, it works well with a high-speed application and contributes to the reduction of equipment cycle time.

応答周波数

What is response frequency?

応答周波数とは？

A rotating plate having the standard sensing object pasted at constant intervals is placed in front of the proximity sensor. The plate is rotated while observing the sensing output. The maximum number of times per second at which sensing can be done, for which the corresponding sensing output can be obtained, is the maximum response frequency.

In other words, the larger the numeric value of the response frequency is, the faster the response is.
Example) Conversion of response frequency to response speed
1 kHz → 1-ms cycle
5 kHz → 0.2-ms cycle

Enhanced a degree of the detection margin

Sensing over long distance
The M8 / M12 / M18 / M30 threaded type sensors are available in standard sensing range type or long sensing range type ("K" at the end of model No.).
The long sensing range means reliable detection with plenty of performance margin to spare.

 

検出距離比較

Minimum risk of collision or sensing error even if the distance to the sensing object changes due to equipment vibration
If the distance to the sensing object changes due to equipment vibration or time-related degradation, the sensor may generate sensing errors including sensing failure in some cases.
If the sensor is set up very close to the sensing object for the purpose of preventing detecting failures, the sensor may contact the sensing object and cause damage.

The long sensing range models facilitate the sensor setup for reliable sensing since they detect the sensing object at a long distance.

装置の振動により検出物体との距離が変動しても衝突や検出ミスが起きにくい

Reduced variation in maximum operation distance
With the GX-300 series, variation in maximum operation distance is kept within ±10%
* ±15% in the case of the previous GX series.
Variation in the maximum operation distance of the ø3 / ø4 / ø5.4 mm ø0.118 / ø0.157 / ø0.213 in, M5 / M8 threaded type models has been also reduced as compared to the conventional models.

ユーザビリティ向上

Indicator with significantly improved visibility

The indicator is conveniently visible from any direction, thus facilitating installation check and operation confirmation.

従来
If the operation indicator position is adjusted to make the indicator visible, the sensor distance changes.
GX-300
In the small-diameter type sensors, the indicator light is visible at 4 locations. In the M8 and larger threaded type sensors, the high-brightness indicator and the resin containing dispersing agent provide clear and highly visible light to facilitate the cumbersome adjustment of installation position.

* The indicator light may appear differently depending on ambient environments and brightness.
* On the M8 and larger threaded type sensors, the indicator light is visible at 2 locations on one side.
* The operation indicators of the M8 and larger threaded type sensors flash in green during IO-Link communication.

Further reduction of the size of small-diameter type sensors for easier embedment

The small-diameter type sensors are 25.1 mm 0.988 in in depth while the conventional models measured 30 mm 1.181 in.
(GX-303S measures 27.1 mm 1.067 in in depth.)
The reduced unit size enables the installation of the sensor in a smaller space.

IoT化に貢献

IO-Link compatibility

Evolution from ON/OFF judgment sensors to sensors capable of transmitting the detection level and sensor status information
* Only the M8 / M12 / M18 / M30 threaded type, PNP output, normally open type models are compatible with IO-Link.

◆     IO-Link compatible sensors can also be used as ordinary sensors (PNP output type).

◆ When IO-Link compatible sensors are connected to the IO-Link master, they can transmit not only ON/OFF signal but also sensor level information and operation mode switching information in both ways. So, the sensors can be utilized for the visualization of manufacturing operations or for the incorporation of IoT technology.

Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73 ℉.

2) The sensors with "N" indicated instead of □ in their model Nos. are NPN output type. The sensors with "P" are PNP output type.

3) The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object. The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation.

4) When used at a power of 12 V, the product is less susceptible to the effects of internal self-heat generation and therefore a more stable repeat accuracy can be obtained.

5) When the output is 20 mA or less, the product is less susceptible to the effects of internal self-heat generation and therefore a more stable repeat accuracy can be obtained.

6) When the cable length is 2 m 6.562 ft.

7) The response frequency is an average value.

8) The bending-resistant cable type models come with a 0.15 mm2 3-core bending-resistant ø2.9 mm ø0.114 in cabtyre cable.

Installing small-diameter sensor

  • Please use the sensor after confirming the installation distance by following (a) and (b) with an actual detection object when you install.

(a) The detection distance receives the influence by the material of the detection object, thickness, shape, and the size. So, the detection object is brought close to the front side of the sensor and detection distance (S) is measured. For the effect of the material, see the graph, "Correlation between sensing object size and sensing range".

(b) Please decide installation distance (Sa) with S × 70% or less after measuring sensing distance(S).

  • Please use the sensor after confirming the installation distance by following (a) and (b) with an actual detection object when you install.
  • Please install the sensor to come within the range of (Sa) when the detection object moves from vertical direction.
  • Please install the sensor to pass within the range of (Sa) when the detection object moves from horizontal direction.
  • When using the sensor, refer to the "Standard sensing object" specified in the specifications and the graph, "Correlation between sensing object size and sensing range".
