設計定制：
多通道磁霍爾效應接近傳感器（有很強的接近檢測穩(wěn)定性）
要求：
1. 分辨率： 1微米
2. 量程（測量范圍）：0-200微米
3. 傳感器尺寸： 3-4 mm，
4. PCB尺寸： 總長 180mm, 寬10-15mm
5. 輸出：串行輸出（通過SPI接口傳輸數(shù)據(jù)）1 serial output. Every 250 microsecond we need to send a string:(Channel1[12 Bit], Channel2[12 Bit],…..., Channel30[12Bit])
6. 通道： 30個通道，
7. 抽樣：30通道，總共250微秒 （Sampling -250 microsecond for all 30 channels together）
8. 成品：PCB(印刷電路板）。 We need the PCB. From one side – Hall Sensors. From another side – the electronics. Probably, we will need a small additional PCB to be connected to OUR OWN electronic board: the RECEIVER.
解釋：
一面有30個磁霍爾傳感器鑲嵌在PCB上，另一面是electronics。 每個磁霍爾傳感器裝在一個金屬球軸承旁，每 個球軸承可以移動， 最多可以移動0.2mm(200微米）， 總共有30個球軸承，每個磁霍爾磁性傳感器可以感覺到球軸承的運動，用1微米的精度來測量運動。30個信號從30個磁霍爾傳感器發(fā)送到電子板，這30個信號需序列化成一行。每行到達250 微秒, 可以通過SPI接口傳輸數(shù)據(jù)

以下是適合的系統(tǒng)，但是技術不同，這是一個磁阻傳感器, 很精確但是很貴，對于我們來說霍爾傳感器就夠了

Predict Purchase quantity
5,000-10,000 PCB (150,000-300,000 sensors) in 2017, then up to 50,000-100,000 PCB per year.
Partners
The Manufacturer that offer customization service.
The company offer electronic design services.
The person who can offer electronic design services.
The partners should offer drawings, working prototype, elevation sample for factory, cost for the customization. if produce, better to offer unit price, time , payment term.
Customization:
Multichannel magnetic Hall effect proximity sensor( have superior proximity stability )
Specification as follow
Resolution : 1 micrometer
Measurement range： 0-200 micrometers
Size for the sensor： 3-4 mm，
PCB Size： Totally, the PCB is 180mm, width is 10-15mm
Output： Serial output ( SPI interface to transmit the data ) 1 serial output. Every 250 microsecond we need to send a string:(Channel1[12 Bit], Channel2[12 Bit],…..., Channel30[12Bit])
channels： 30 channels
Sampling ： 30 channel, totally 250 microsecond（Sampling -250 microsecond for all 30 channels together）
Completed product： PCB( printed circuit board） We need the PCB. From one side – Hall Sensors. From another side – the electronics. Probably, we will need a small additional PCB to be connected to OUR OWN electronic board: the RECEIVER.
Explanation:
（this PCB should contain 30 sensors from one side and the electronics from another side.The sensor should be mounted on PCB, each sensor is placed near a metal ball bearing,Each ball bearing can move a little, maximum 0.2mm, which is 200 micrometers.There are 30 ball bearings. Each magnetic sensor can feel the movement of the ball bearing.We need to measure this movement with the precision of 1 micrometer.It should be magnetic hall effect sensors. Then we need 30 signal ( from 30 sensors) to send to our electronic board. These 30 signals should be serialized into one line. Each line should come every 250 microsecond.The data can be transmitted through an SPI interface.）

Th following is a suitable system, but different technology, This is a magneto resistive sensor, it is very precise but very expensive. For us , the hall effect sensor is enough.
