應用程式提示

While a switching power supply is used, please be sure to ground the FG (Frame ground) and the G (Ground) terminal, if failure to do so, it may resulting malfunction of the sensor for the noise of the switching power supply. Meanwhile, the ripple of the DC power supply is required less than 20% to avoid resulting malfunction of the sensor.

基本定義

Target/標準檢測物
Whick is teel, 1mm thickness, square form with width equal to the diameter of the sensing surface, if the target is made of a different material, the sensing distance must be multiplied by the Correction factor.
標準檢測物是方型鐵片，厚度1mm，長寬等於感測器的感應面直徑。如果標準檢測物的材質不是鐵則感測距離須依右圖的修正係數修正。

Hysteresis /應差
Hysteresis is the different distance between the operating points that the target is approaching and leaving the sensing area of the sensor, the value is expressed as a percentage of the sensing distance (Ad/Sn%)
應差是感測器的動作點與復歸點的距離，一般是以動作點與復歸點的距離除以感應距離後以百分比表示。

Switch frequency/響應頻率
It is the maximum response frequency per second, based on a pulse ratio 1:2, the sketch shows the condition of test.
響應頻率是以ON/OFF比=1:2的條件所測得每秒最高響應頻率。測試條件如右圖所示。

Accuracy (Repetition) / 重複精度
Tolerance of operating position that sensor is certainly operated under the same condition.
在相同的條件下所測得的最大動作點與最小動作點的差值。

安裝注意事項

Flushed type / 埋入式
A proximity sensor can be flushed mounted in metal and surrounded by metal up to the level of the sensing face.
近接感測器可完全埋入金屬物即感應面四周可受金屬物包圍。

Non-flushed / 非埋入式
A proximity sensor cannot be mounted in metal, clear zone of 3 times of the diameter of the sensing surface must be keep.
近接感測器感應面四周不可受金屬物包圍，淨空範圍必須是近接感測器感應面直徑的三倍距離以上。

Mutual interference / 互相干擾
To install the inductive proximity sensors of the same model by face to face or side by side, please set the minimnm distance between the sensors larger than the diameter of sensor, to avoid the malfunction.
近接感測器不可以面對面或並排方式安裝，如果要以上數方式安裝務必保持近接感測器感應面直徑的一倍距離以上。

Clamping torque / 鎖緊扭力
Be sure to set a spring washer when fixing the sensor, Don't tighten the mounting screw of PM series with a clamping torque higher than the right value.
安裝近接感測器時務必使用止滑墊圈以防止鬆脫。安裝 Pm系列近接感測器時鎖緊扭力請勿超出最大扭力值以免損壞近接感測器。

Notice of Wiring / 配線注意事項
To avoid being influenced by noise, try best to separate the cable of the sensor from the power lines and high tension lines. if extend the sensor cable, please use a cable which diameter as same as that.
避免雜訊干擾，請盡量將感測器的電線與動力線或高壓線分離，不要綁在一起。如果要延長感測器的電線請盡量使用和感測器的電線相同規格的電線。
