Re: [Emc-users] Possible lathe spindle encoder.
Andy, I read the datasheet and it looks really easy. The dual channel is the independent output of the two hall effect transducers (available only in the surface mount part.) The other two outputs are direction (simple binary pin) and speed. Speed is the XOR of the two transducers, so it produces a full square wave for each magnet pass under the device. You can then either time between edges of the square wave to get an instantaeous angular velocity or between square waves to get the rotation rate. Way easier that looking for a missing pulse. at $2.50 each, this is a cool part. The weird thing is the 26.5V supply voltage (clearly made for one customer...). That means an extra power supply and level converters on the outputs. It would be nicer if there was a 5V part (I didn't look for one.) Given that it's built for automotive, it is as close to indestructable as you can easily get for an electronics part. jerry On Wed, Jul 29, 2015 at 10:45 AM, andy pugh bodge...@gmail.com wrote: On 29 July 2015 at 18:41, andy pugh bodge...@gmail.com wrote: I can't find a source for the sensor in the US.

Does Ford buy them via Amazon ?? ;-) The price is right. http://www.amazon.co.uk/Febi-36070-Crankshaft-Timing-Wheel/dp/B00CD3DHXO I can't find a source for the sensor in the US. Dave On 7/28/2015 6:01 AM, andy pugh wrote: Now that many cars have automatic stop/start there is a requirement for bidirectional crank position sensors. (So that the PCM can track crank position if the crank rocks-back and still fire on the first TDC). The sensors are (often) a magnetic track on the outside of a wheel. The ones I have here a central boss with a 30mm bore, but this is pressed into a sensor ring with a 70mm bore, which would be adequate for quite large spindles. A typical encoder ring is Ford part number 7M5Q-6B319-BA which costs £50 inclusive of VAT. The sensor is DS7Q-9E731-BA and costs £23 The encoder protocol is a bit unusual. Index is indicated by a missing pulse, and direction is indicated by pulse length. So some changes would be needed to the encoder component to support this class of device. On the plus side you get index and direction for only one IO line. I don't actually know what sensor is the Ford package however I have found a direction-detecting sensor for ferrous targets such as gear wheels here: http://www.allegromicro.com/~/media/Files/Datasheets/ATS693-Datasheet.ashx?la=en It isn't clear if that one can use missing-tooth index, it looks like it might reject it as a vibration artefact. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

[Emc-users] Switches for home, limits
I bought a bag of small, roller tipped microswitches, and have a couple mounts laid out but not carved yet. Going thru searches on ebay just now, for both inductive, capacitative, and IR proximity switches, It sees like the majority of them are needing 6 volts or more, and around 300 ma each to function. Having seen some micropower capacitative switches in the textbooks of yore, it seems like the ball has been dropped in terms of being useful in a 5 volt logic circuit. Both the microswitch, and the inductive versions would seem to be sensitive to collecting swarf, particularly if its a rare earth magnet running a reed switch. My lathe seems to be relatively happy with a microswitch located under the back edge of the bed for Z homing where swarf tends to fall on past it, but x has to be kept swept clean because its actually on top of the carriage. I see a whole passel of stuff drilled onto GO704's in the hits I can get from google, but all of them preclude retaining the rubber swarf shields, which I'd say was not worth the tradeoff. There has to be a better way. So what sort of switches, and what swarf shielding to keep them relatively clean accurate are others using? PM's with pix appreciated if you have the time. Thanks.
