* 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.

What is response frequency?

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

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.

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.

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.

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

If the operation indicator position is adjusted to make the indicator visible, the sensor distance changes.

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 allow the confirmation of the indicator from any angle to facilitate the cumbersome adjustment of installation position. * The operation indicator flashes in green during I/O-Link communication.

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.

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. * CC-Link IE Field and CC-Link are trademarks of Mitsubishi Electric Corporation, and are controlled by the CC-Link Partner Association.
