預(yù)計(jì)采購(gòu)數(shù)量：

5,000-10,000 PCB (150,000-300,000 傳感器）in 2017. 每個(gè)pcb 上鑲嵌30個(gè)接近霍爾傳感器

2017 年以后的采購(gòu)量50,000-100,000PCB system, ( 1500,000-3000,000 傳感器）每年。

設(shè)計(jì)定制：

多通道磁霍爾效應(yīng)接近傳感器（有很強(qiáng)的接近檢測(cè)穩(wěn)定性）

要求：

1. 分辨率： 1微米

2. 量程（測(cè)量范圍）：0-200微米

3. 傳感器尺寸： 3-4 mm，

4. PCB尺寸： 總長(zhǎng) 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(gè)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(gè)磁霍爾傳感器鑲嵌在PCB上，另一面是electronics。 每個(gè)磁霍爾傳感器裝在一個(gè)金屬球軸承旁，每 個(gè)球軸承可以移動(dòng)， 最多可以移動(dòng)0.2mm(200微米）， 總共有30個(gè)球軸承，每個(gè)磁霍爾磁性傳感器可以感覺到球軸承的運(yùn)動(dòng)，用1微米的精度來測(cè)量運(yùn)動(dòng)。30個(gè)信號(hào)從30個(gè)磁霍爾傳感器發(fā)送到電子板，這30個(gè)信號(hào)需序列化成一行。每行到達(dá)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(shù)不同，這是一個(gè)磁阻傳感器, 很精確但是很貴，對(duì)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.
