Look what I found! Link Galvanic seperation with capacitors! Now we are talking this would cost a standard driver chip and a few cents more.
But with a 10 lower frequency would mean a lot more phase difference and with capacitors on both sides of the cable would that mean doubling the capacitor...
The ethernet idea would be a possibility however the chip is .80$ but also there is a 2 to 3$ pulse transformer used. (HX1198FNL). Also the ethernet is full duplex and I was thinking more like half duplex. I'll have a look if a re-design to full duplex would make sense. I'll also have a look at...
Sorry took me a while to grasp the abbreviations no infrared and bluetooth isn't really an option. Really need to use good old copper. Also had a look at plastic fiber what might be a potential solution but is also too expensive and too fragile at the connector sides. Main use is machine building.
Hi I'm trying to find a cheap solution for a galvanic separated point to point RS485 bus. I need to send data between these 2 points in 1/2 duplex. There are full solutions for it like the www.linear.com/product/LTM2881 however these are very expensive and I would blow my complete budget on...
Hi,
I have the following challenge. I need to seal 3 to 6 mm cables in a 6.5 mm hole. There can be different jacketing materials on the cable PVC, PUR or Low smoke non halogen jackets. The seal has to meet IP65 (dust and water resistant) . be as chemical resistant as possible and should act as...

Have been there however the problem is that as soon as you mention positioning the mind set is servo motor.
Had long discusions with Siemens on the subject they can do it but total KW is around 5* the amount I put in the hyrdaulic application making it too expensive to go electrical. I haved...
Need some help:
Problem; high torque positioning application (2000N/M) but need high dynamics (5rad/sec(2)). Only need the high dynamics at low torque.
Standard servomotors get way too big to reach the above or with a high ratio gearbox not dynamic enough.
In principal a traditional serial...
